What best describes the relationship between line 6x - 2y = 1 and the line x + 3y = 12?
is it parallel, perpendicular, or neither?
Answers
Both the lines are perpendicular lines.
What is Equation of line?The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation of lines are,
⇒ 6x - 2y = 1 and x + 3y = 12.
Now,
Since, The equation of lines are,
⇒ 6x - 2y = 1 and x + 3y = 12.
Hence, Find the slopes of the lines as;
⇒ 6x - 2y = 1
⇒ 2y = 6x - 1
⇒ y = 3x - 1/2
⇒ m₁ = dy/dx = 3
And, From second line,
⇒ x + 3y = 12.
⇒ 3y = - x + 12
⇒ y = - 1/3x + 4
⇒ m₂ = dy/dx = - 1/3
Clearly, We get;
⇒ m₁ m₂ = 3 × - 1/3
= - 1
Thus, Both the lines are perpendicular lines.

Answer:

Step-by-step explanation:
We see that x represents the number of 10-oz boxes sold. Then y=24-x is the number of 16-oz boxes sold. Substituting for y in the second equation gives ...
3.50x +5.00(24 -x) = 97.50
-1.50x +120 = 97.50
22.50 = 1.50x . . . . . . . add 1.50x -97.50

Step-by-step explanation:
A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). The one-time fixed costs will total $53,150. The variable costs will be $12 per book. The publisher will sell the finished product to bookstores at a price of $24.50 per book. How many books must the publisher produce and sell so that the production costs will equal the money from sales?
Answers
Answer:
12x +53,150 = 24.5x (production cost = revenue )
53,150 = 12.5x (subtract 12x from both sides and then divide 53,150 by 12.5)
x= 4,252 books

Answer: The first and last table.
As the x increases by 2, the y goes down by 1, so both tables have the same rate of change which means they are the same function.
Tables 1 and 5 are equal.
Given are 5 tables in x and y with two values each.
We are to find out which two represent the same function.
As for every function, two points are given.
Let us compare the slopes of each function.
Slope=change in y coordinate/change in x coordinate
Table Slope
I -0.5
2 -0.5
3 -0.5
4 1
5 -0.5
Table 4 is eliminated now.
Though slopes are the same for 1 and 2,f(4) =8 and 5 different . Hence I and II cannot be the same. Similarly for 2 different values are there in table 3,4,5. Hence 3,4,5 cannot be pairwise equal.
We find that table I and table 5 have the same slope. Also when pairwise taken, (4,8) and (2,9) slope = -0.5
So table I = table 5

In the figure above, AB = AD, BC = CD, BE = 2, BC = 4, and AC = 10. What is the area of triangle ABD?
Answers
The properties of items in a question can be used to simplify the solution to the questions
The area of triangle ΔABD is 20 - 4·√3
The reason the above value for the area of ΔABD is correct is as follows:
The given parameters are;
AB = AD, BC = CD, BE = 2, BC = 4, AC = 10
Given that AB = AD, and BC = CD, we have that the figure ABCD is a kite
∴ AC is perpendicular to BD by properties of the diagonals of a kite
ΔBCE is a right triangle
By Pythagoras' theorem, [tex]\overline{CE}[/tex]² = [tex]\overline{BC}[/tex]² - [tex]\overline{BE}[/tex]²
Which gives;
[tex]\overline{CE}[/tex]² = 4² - 2² = 12
[tex]\overline{CE}[/tex] = 2·√3
Given that AC is the perpendicular bisector of BD, by the properties of a kite, we have;
BD = BE + DE, where BE = DE definition of bisected line
∴ BD = BE + BE = 2·BE
Area of a triangle = (1/2) × Base length × Height
AE = The altitude (height) of the ΔABD = AC - CE
∴ AE = 10 - 2·√3
BD = The base length of ΔABD = 2·BE (Length of BE = 2)
∴ BD = 2 × 2 = 4
The area of triangle ΔABD = (1/2) × BD × AE
∴ The area of triangle ΔABD = (1/2) × 4 × (10 - 2·√3) = 20 - 4·√3
The area of triangle ΔABD = 20 - 4·√3

Answers
Answer:
k = 0
Step-by-step explanation:

Step-by-step explanation:
We can find the answer to this question by using the slope equation:
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's define some variables:
[tex]\frac{k - 7}{-7-(-8)} = \frac{k-7}{1} = k- 7[/tex]
We know the slope is -7 so we can put k-7 equal to it and solve
[tex]k-7 = -7\\k = 0[/tex]
We find that k is equal to 0.

b. maximum at x = 1.25
c. minimum at x = -1.25
d. minimum at x = 1.25

Answer: D
Explanation:
Use the vertex formula, -b/2a. Because the quadratic formula is ax^2+bx+c, -b would be 5 in this case and a would be 2 in this case. Plug the numbers in and you get 5/4. The AOS or vertex would be 5/4 or 1.25. Because the a-value is a positive in this equation, the parabola would have a minimum.
