What are the equations of lines m and q?
Equation of 'm'
(y - 6) = - ³/₅ (x - 2) [point-slope form]
y = - ³/₅ x + ³⁶/₅ [slope-intercept form]
Equation of 'q'
(y - 6) = ⁵/₃ (x - 2) [point-slope form]
y = ⁵/₃ x + ⁸/₃ [slope-intercept form]
How to find the equations of lines m and q?To find the equation for both 'm' and 'q' requires a bit of work. Because neither 'm' nor 'q' has two points to find the slopes of the line, we have to get creative.
The Line 'n' has two points [ (4, 4) & (1, -1) ], and as such we can find the slope of that line. The line 'n' is parallel with 'q' and perpendicular with m.
For finding the slope of 'n'
The slope of the 'n' = (y₂ - y₁) ÷ (x₂ - x₁)
= (4 - (- 1)) ÷ (4 - 1)
= 5 ÷ 3
= ⁵/₃
To estimate the slope of 'q' and 'm'
When two lines exists parallel, they contain the exact slope.
Since 'n' and 'q' exists parallel,
then the slope of q = ⁵/₃
When two lines exists perpendicular, the product of their slopes exists -1. This means that the slopes exists negative-reciprocals of each other.
Since 'n' and 'm' exists perpendicular
then the slope of m = - ³/₅
Write the equation for 'q' and 'm'
We can now utilize the point-slope form (y - y₁) = m(x - x₁)) to write the equation for the lines
For both 'q' and 'm' let (x₁, y₁) be (2, 6)
Equation of 'm'
(y - 6) = - ³/₅ (x - 2) [point-slope form]
y = - ³/₅ x + ³⁶/₅ [slope-intercept form]
Equation of 'q'
(y - 6) = ⁵/₃ (x - 2) [point-slope form]
y = ⁵/₃ x + ⁸/₃ [slope-intercept form]

How many adult patrons were there?
There were adult patrons.
In linear equation, No of Adults = 2,179, No of Children = 3,221 .
What in mathematics is a linear equation?
An x-y linear relationship, or two variables in which the value of one of them (often y) relies on the value of the other one, is what is known as a linear equation in two variables (usually x).The dependent variable in this scenario is y since it depends on the independent variable, x.Let Number of Adult admission be x
Number of children's admission be y
Total tickets were sold = 5400
so x+y= 5400 ....... eq 1
One adult ticket costs $5.50 ,so total Adult ticket costs = 5.50x
One Child ticket costs $ 3.50, so total Children tickets cost= 3.50 y
receipt totaled = $23,258
so 5.50x+3.50y= $23,258....... eq 2
multiply 5.50 to the eq 1, we get,
5.50x +5.50y = 29,700...... eq 3
subtract eq 2 from eq 3, we get,
5.50y-3.50y = 29,700- 23,258
2y= 6,442
divide by 2 both sides ,we get, y= 3,221
substitute the value of y in eq 1, we get,
x+ 3,221 =5400
x= 5400- 3221
x= 2,179
No of Adults = 2,179, No of Children = 3,221

Consumer Economics Each family in a neighborhood is contributing $20 worth of food to the neighborhood picnic. The Harlin family is bringing 12 packages of buns. The hamburger buns cost $2.00 per package. The hot-dog buns cost $1.50 per package. How many packages of each type of bun did they buy?Choose the correct equation that represents the number of buns purchased. [ Select ]Choose the correct equation that represents the cost of the buns. [ Select ][ Select ] packages of hamburger buns were bought.[ Select ] packages of hot dog buns were bought.
Explanation
In the question, we are given some important details to work with. Here is a list of them.
1) First, we must note that each family is contributing $20 worth of food.
2) Harlin's family brought 12 packages to the party.
3) The 12 packages consist of two types of buns namely hamburgers and hot dogs. The hamburger buns cost $2 per package while the hot-dog buns cost $1.50
Part A
Let's assume that the number of hamburger packages represents x and the number of hot dogs packages represents y. We can conclude that the sum of bought packages should be equal to 12. We can then translate this information into the equation below.
[tex]x+y=12[/tex]Answer A: x+y = 12
Part B
Now, we can figure out the equation that represents the cost of the buns. Since we know the cost of each buns package, we can multiply the cost of each buns package by the number of packages that were brought to the party by the Harlin family.
Also, we will add the resulting expressions and equate it to the cost of the worth of food each family will bring to the party.
Therefore,
[tex]\begin{gathered} Total\text{ cost of hamburgers = }2\times x=2x \\ Total\text{ cost of Hot dogs = 1.50 x y =1.5y} \\ \therefore\text{Tota cost of buns }\Rightarrow\text{ }2x+1.5y=20 \\ \\ \end{gathered}[/tex]Answer B: 2x+1.5y = 20
Part C And Part D
The above sections can be gotten by solving the previous systems of equations simultaneously. Therfore,
[tex]\begin{gathered} x+y=12\text{ -----1} \\ 2x+1.5y\text{ =20 -----2} \end{gathered}[/tex]Let's create equation three from equation 1
[tex]x=12-y-----3[/tex]Then we will substitute equation three into the untouched equation 2
[tex]\begin{gathered} 2(12-y)+1.5y=20 \\ 24-2y+1.5y=20 \\ 24-0.5y=20 \\ -0.5y=20-24 \\ -0.5y=-4 \\ y=\frac{-4}{-0.5} \\ y=8 \end{gathered}[/tex]
Use the graph of the exponential function to answer the following question.Which statements about the graph are TRUE? Select all that apply. A. The x-intercept is 2. B. The y-intercept is 3. C. The asymptote is y = -1D. The range is all real numbers E. The domain is all real numbers F. The function shows growth G. As x increases, y approaches, but never reaches, -1
The curve intersect the x axis at x = 1. So x-intercept is 1. Statement A is false.
The curve intersect the y-axis at y= 3. So y intercept is 3. Statement B is correct.
The curve tends toward infinity at y = -1. So y = -1 asysmptote of the function. Statement C is correct.
The range of function is y > -1. So range is not all real number. Thus statement D is incorrect.
The function is defined for x > -0.5. At x = 0.5 function tends toward infinity. Thus statement E is incorrect.
As we move from left to right on x-axis then function decreases. So function shows decay. The statement F is incorrect.
The value of function approaches -1 as value of x increase but does not cross -1 ot touch the value y = -1. So statement G is correct.
Thus correct statement are,
B, C and G.
100 students took an exam, the maximum score was 90. From the graph, 1.what was the median score?2.Also, find the lower quartile score. in reference to the first question. 3. what is the inter-quartile score range score?
0. From the given graph, the cumulative frequency value indicates the number of students, we have 100 total number of students .
• so,Median is half of the students = 100/2 = 50
the value of test score that corresponds with 50 = 55 test score
• This means that the median , 50 students scored 55 % in the exa,m.
2. Finding the lower quartile Q1 :
since we have 100 students , 100/4 = 25, so Q1 = 25
the value that corresponds with cumulative frequency of 25 = 45
• This means that 25 students scores 45 %
3. Finding the Interquartile range :
IQR = Upper Quartile -Lower Quartile
Upper quartile = Q3 = 75 students : 60 %
and lower quartile = 45%
So,
IQR = 60-45
= 15
• This means that 15 students got 35 %

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]In this case you know that:
[tex]m=-8[/tex]Knowing the following point on the line:
[tex]\mleft(10,27\mright);(11,a)[/tex]You can set up the following (substituting the slope and the coordinates of those point into the formula)
[tex]-8=\frac{27-a}{10-11}[/tex]Now you can solve for "a":
[tex]\begin{gathered} (-8)(-1)=27-a \\ 8-27=a \\ -19=a \\ a=19 \end{gathered}[/tex]The answer is: Third option.
Simplify the expression to a + bi form:(12 – 6i)(3 – 10i)
Solution:
Given the expression:
[tex](12-6i)(3-10i)[/tex]To simplify in the form:
[tex]a+bi[/tex]step 1:
Multiply the terms in the second parenthesis by each term in the first parenthesis.
Thus,
[tex]\begin{gathered} 12(3-10i)-6i(3-10i) \\ \Rightarrow36-120i-18i+60i^2 \end{gathered}[/tex]step 2:
Collect like terms.
[tex]\begin{gathered} 36-120i-18i+60i^2 \\ \text{but } \\ i^2=-1 \\ \text{thus,} \\ 36+60(-1)-120i-18i \\ \Rightarrow36-60-120i-18i \\ =-24-138i \\ \Rightarrow-24+(-138)i \end{gathered}[/tex]Hence, the expression is simplified as
[tex]-24+(-138)i[/tex]Write an equation for a line perpendicular to 3 y − 6 x = − 15 and passing through the point (6,-4) y =
The equation of the line perpendicular to 3y-6x = -15 and passing through the point (6,-4) is y = (-1/2)x - 1
The equation of the line is
3y-6x = -15
Convert the equation to the slope intercept form of the line
3y-6x = -15
3y = 6x-15
y = (6x-15)/3
y = 2x-5
The slope intercept form of the line
y = mx+b
By comparing the result with slope intercept form
slope of the line m = 2
The slope of the line perpendicular will be the negative reciprocal of 2
m = -1/2
Therefore the slope of the line will be
y = (-1/2)x+b
The line is passing through the point (6,-4)
Substitute the values in the equation
-4 = (-1/2)×6+b
-4 = -3+b
b = -4+3
b = -1
Substitute the values in the slope intercept form
The equation of the line perpendicular to 3y-6x = -15 and passing through the point (6,-4)
y = (-1/2)x - 1
Hence, the equation of the line perpendicular to 3y-6x = -15 and passing through the point (6,-4) is y = (-1/2)x - 1
The complete question is

If the measure of angle 1 = 2x+3 and the measure of angle 2 = 3x+2, then what is the measure of angle 3?
Answer: 126°
Step-by-step explanation:
Step-by-step explanation: Since every triangle has 180 interior degrees, we can say 2x + 3x + 90° = 180°. Subtract 90° from each side and we get
2x + 3x = 90°
5x = 90°
x = 18°
Plug in x for Angle 2, giving us Angle 2 = 54°
Angle 1 and angle 2 must add up to 180°
Subtract 54° from 180° and we get 126°
Line a is parallel to line b. Which list shows accurate angle relationships?
Given:
Line a is parallel to line b.
As shown:
m∠1 = m∠5 ; the corresponding angles are congruent
m∠2 = m∠2 ; the corresponding angles are congruent

When solving an equation with one variable on both sides what are three types of solutions youcan obtain?
whenever you have an equation with one variable on both sides, you might end up with one of the following case:
1. You might end up with an inconsistent equation, therefore there is not solution. Example
x = x+3. If you subtract x on both sides, you get 0=3 which is impossible.
2. You might end up having infinite solutions. Example:
x+6 = x+6. If you subtract x on both sides you get 6 =6 which is true regardless of the value of x.
3. You might end up having only one solution. Example:
3x +2 = x +5
If you subtract x on both sides and subtract 2 on both sides, you get
2x = 3.
then if you divide by two on both sides, you find
x = 3/2. So this equation has one unique solution.

the yearly salary ($29,700) is the gross pay she gets.
the gross pay minus the taxes ($2,948 and $2,573) is then the net pay she receives.
in many cases the employer also withholds the health insurance premium (and then that has to be subtracted too before getting the net pay).
I just think your teacher means by "net pay" how much she will have left are all the monthly costs.

$29,700 - $2,948 - $2,573 = $24,179
the monthly net pay is $24,179/12 = $2,014.916666... ≈
≈ $2,014.92
she has to pay monthly
$140
$ 65
$300
$675
$130
$ 55
$278
$220
---------
$1,863
based on her monthly net pay she has left
2,014.916666...
- 1,863
---------------------------
151.9166667 ≈ $151.92
per month
please pick based on what you think your teacher means by net pay : the actual net pay by her employer, or how much money she has monthly left after paying all bills.
I need to write an explicit formula for this problem but I have not idea what I'm doing.
Given data:
The given series is -32, -25, -18, -11,....
The commo difference of the given series is,
[tex]\begin{gathered} d=-25-(-32) \\ =-25+32 \\ =7 \end{gathered}[/tex]The expression for the explicit formula for the given series is,
[tex]\begin{gathered} a_n=a+(n-1)d \\ =\text{ -32+(n-1)}(7) \\ =-32+7n-7 \\ =-39+7n \end{gathered}[/tex]The expression for recursive formula is,
[tex]\begin{gathered} a_n=a_{n-1}+d \\ =\lbrack-39+7(n-1)\rbrack+7 \end{gathered}[/tex]
