Find the point slope equation of the line through (0,7) with slope of 6.
Answer:
y-7= 6(x-0)
Step-by-step explanation:
y-y1=m(x-x1) is the point slope form. The slope is substituted by the m while (x1,y1) are any coordinate on the plane. As you already have to coordinates (0,7) and the slope of 6 substitute it into the equation, to get y-7=6(x-0). Hope this helps!

What is x, the distance across the lake?
Answer:
45.5
Step-by-step explanation:
You do the linear length multiplied by the longitudinal length
The distance across the lake is 320 ft.
Given is a scenario of a lake, a survey crew has laid out the concept of similar triangles to find the distance across the lake.
The figure shows the base of the larger triangles is the distance across the lake. [please refer to the figure attached]
The dimensions of the imaginary triangles are 30 ft, 30 ft, 40 ft and 240 ft, 240 ft, x ft.
Here, x is the distance across the lake which we are asked to find.
Using the definition of the similar triangles,
Two triangles are considered similar if their corresponding angles are equal, and the ratios of the lengths of their corresponding sides are equal.
So,
[tex]\frac{240}{30} = \frac{x}{40}[/tex]
[tex]x = \frac{240 \times 40}{30}[/tex]
x = 320
Hence the distance across the lake is 320 ft.

The concession stand at a football game sells hot dogs and drinks. It costs $4.25 for 2 hot dogs and 1 drink. It costs $7.00 for 3 hot dogs and 2 drinks. Which of the following systems of equations can be solved to determine the cost, h, of each hot dog and the cost, d, of each drink
Answer:
h = $1.50
d = $1.25
Step-by-step explanation:
$1.50 + $1.50 = $3 + $1.25 = $4.25
$1.50 + $1.50 + $1.50 = $4.50 + $1.25 + $1.25 = $7
Answer:
2h + 1d = 4.25
3h + 2d = 7.00
Step-by-step explanation:
-3(2h + 1d) = -3(4.25)
2 (3h + 2d) = 2(7.00)
-6h - 3d = -12.25
6h + 4d = 14
if we add them together we get D = 1.75
Checking:
2h + 1(1.75) = 4.25
2h + 1.75 = 4.25
2h = 2.5
h = 1.25
1.25 times 2 plus 1.75 = 4.25

Consider a cookie recipe in which 1 1/2 cups of chocolate chips are needed to make 25 cookies. Lara wants to double the number of cookies. How many cups of chocolate chips should she use?
Answer:
[tex]Cups = 3[/tex]
Step-by-step explanation:
Given
[tex]Cups = 1\frac{1}{2}[/tex]
[tex]Cookies = 25[/tex]
Required
Number of cups when the cookies is doubled
When [tex]Cookies = 25[/tex], [tex]Cups = 1\frac{1}{2}[/tex]
So, when the number of cookies is doubled, the number of cups will also be doubled.

Find the angles:
m∠A = 2/3x°
m∠P = 4/5x°
∠A and ∠P are supplementary.
9514 1404 393
Answer:
m∠A = 81 9/11°
m∠P = 98 2/11°
Step-by-step explanation:
Supplementary angles have a total of 180°, so we have ...
m∠A +m∠P = 180°
2/3x° +4/5x° = 180°
22/15x° = 180°
x = 122 8/11 . . . . . . multiply by 15/22
Then the angles are ...
m∠A = (2/3)(122 8/11)°
m∠A = 81 9/11°
m∠P = (4/5)(122 8/11)°
m∠P = 98 2/11°
_____
Alternate solution
The fraction of 180° that is ∠A is ...
(2/3x°)/(2/3x° +4/5x°) = (10/15)/(10/15 +12/15) = 10/22 = 5/11
m∠A = (5/11)(180°) = 81 9/11°
m∠P = 180° -m∠A = 98 2/11°
Answer:
m∡A = 81.8°
m∡P = 98.2°
Step-by-step explanation:
2/3x + 4/5x = 180
multiply each side by 15 to eliminate fractions
10x + 12x = 2700
22x = 2700
x = 122.7
∡A = 2/3 (122.7) = 81.8
∡P = 4/5 (122.7) = 98.2

Answer:
y = 8
Step-by-step explanation:
First substitute x with 6 in the equation
2y + 1/3(6) = 18
Multiple 1/3 with 6, which is 2
2y + 2 = 18
Solve the equation by subtracting 2 from both sides
2y + 2 = 18
- 2 - 2
You get 2y = 16, so you divide 2 frm both sides
You get y = 8

What is the criteria for similarity of two triangles?Two triangles are said to be similar when either the ratio of their corresponding sides are equal or all the corresponding angles are equal.
Two similar triangles are the same in shape but not in size.
The given diagram shows two similar triangles as ΔFGH and ΔKJH.
Since the ratios of the corresponding sides of the two triangles are equal, the following equation can be written for the given case as,
(x + 8)/32 = (4x - 25)/52
=> 52(x + 8) = 32(4x - 25)
=> 52x - 128x = -32 × 25 - 52 × 8
=> -76x = -1716
=> x = 22.42
Thus FH = 4x - 25 = 4 × 22.42 - 25 = 64.68
Hence, the length of FH for the given case is 64.68.

Step-by-step explanation:
Solve for x:
(-2 x)/9 = 2/5
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (-2 x)/9 = 2/5 by -9/2:
(-9 (-2) x)/(2×9) = (-9)/2×2/5
Hint: | Express (-9)/2×(-2)/9 as a single fraction.
(-9)/2×(-2)/9 = (-9 (-2))/(2×9):

Hint: | Express (-9)/2×2/5 as a single fraction.

(-9 (-2) x)/(2×9) = (-9×2)/(2×5)
Hint: | In (-9 (-2) x)/(2×9), divide -9 in the numerator by 9 in the denominator.

Jasper is eating tacos at a constant rate. The amount of tacos depends on time.
y= 2.5x
y is the number of tacos eaten
x is the time in minutes
what is the rate of change of jaspers taco eating capabilities?
how many tacos will jasper consume in 9mins
Answer:
The rate of change, I believe, based on what you have given us in terms of information, would be 2.5. Because Jasper would eat 2.5 tacos per minute; thus, the rate would increase by 2.5 each time.
And for the second part, you would simply multiply 2.5 by 9 to get 22.5. Jasper would eat 22.5 tacos in 9 minutes.

bacteria
Answer:
y = 340e^0.0427276t ; 908
Step-by-step explanation:
Given that :
t = time in days since study began
Number of bacteria after 11 days = 544
y = number of bacteria at time t
Exponential growth model:
y = ae^rt
Where a = initial amount ; r = Growth rate
y = 544 ; t = 11 ; a = 340
544 = 340*e^11t
544/340 = e^11t
1.6 = e^11t
Take the In of both sides
In(1.6) = 11t
0.4700036 = 11t
t = 0.4700036 / 11
t = 0.0427276
y = 340e^0.0427276t
Number of bacteria after 23 days :
Using the formula above :
t = 23
y = 340e^0.0427276(23)
y = 340 * 2.6717529
y = 908.39600
y = 908
The required formula is [tex]y = 340e^{0.0427}[/tex]
908 bacteria are there 23 days after the beginning of the study .
Given that,
A certain culture of bacteria has a population of 340.
The population grows according to a continuous exponential growth model. After 11 days, there are 544 bacteria.
We have to find,
Write a formula relating y tot. Use exact expressions to fill in the missing parts of the formula.
How many bacteria are there 23 days after the beginning of the study.
According to the question,
Let t be the time (in days) since the beginning of the study,And let y be the number of bacteria at time,
t = time in days since study began
Number of bacteria after 11 days = 544
y = number of bacteria at time t
Then,
Exponential growth model:
[tex]y = a.e^{rt}[/tex]
Where, a = initial amount ; r = Growth rate
y = 544 ; t = 11 ; a = 340
Then,
[tex]544 = 340.e^{11t}\\\\\dfrac{544}{340} = e^{11t}\\\\1.6 = e^{11t}\\\\Taking \ log \ on \ both \ sides,\\\\ln(1.6) = 11t\\\\0.47 = 11t \\\\t = \dfrac{0.47}{11}\\\\t = 0.0427[/tex]
The required formula is [tex]y = 340e^{0.0427}[/tex]
There 23 days after the beginning of the study Number of bacteria after 23 days :
[tex]y = 340e^{0.0427}[/tex]
Where, t = 23
[tex]y = 340e^{0.0427276(23)}\\\\y = 340 \times 2.6717529\\\\y = 908.39600\\\\y = 908[/tex]

solve the iniquality 6x - 8 > 4x + 26
Answer:
x > 17
Step-by-step explanation:
Add 8 to both sides:
6x - 8 > 4x + 26
6x > 4x + 34
Subtract 4x from both sides:
2x > 34
Divide each side by 2:
x > 17
So, the solution is x > 17
⇢ 6x - 8 > 4x + 26
⇢ 6x > 4x + 26 + 8
⇢ 6x > 4x + 34
⇢ 6x - 4x > 34
⇢ 2x > 34
⇢ x > 34/2
⇢ x > 17
Hence, solution is x > 17.
4x + 3y = -5
-2x+2y = 6
Answer:
4x + 3y = -5
x = −3 /4 y + −5 /4
y = −4 /3 x + −5 /3
-2x+2y = 6
x = y - 3
y = x + 3
Step-by-step explanation:
Solving for x
4x + 3y = -5
4x + 3y + −3y = −5 + −3y
4x = −3y − 5
Then you will divide both sides by 4.
4x /4 = −3y − 5 /4
x= −3 /4 y + −5 /4
Solving for y
4x + 3y + −4x = −5 + −4x
3y = −4x −5
Then you will divide both sides by 3.
3y /3 = −4x −5 /3
y = −4 /3 x + −5 /3
-2x + 2y = 6
Solving for x
−2x+2y+−2y=6+−2y
−2x = −2y + 6
Then you will divide both sides by -2.
−2x/ −2 = −2y + 6/ −2
x = y − 3
Solving for y
−2x + 2y + 2x = 6 + 2x
2y = 2x + 6
Then you will divide both sides by 2.
2y /2 = 2x + 6 /2
y = x + 3
