For an ordered pair to satisfy a function , it's a must that when you plug x , you get the value of y and vise versa :

y = -6x - 2

Check for pair ( -1,-8)

y = -6 * -1 -2 = 6 -2 = 4

y after substitution is not equal to given y ( 8 )

so refused ordered pair.

Check for pair (-3, 16)

y = -6 * -3 -2 = 18 -2 = 16

CORRECT , so this satisfy the function

and so on.

In attempting to solve the system of equations and , John graphed the two equations on his graphing calculator. Because he saw o

asambeis [7]

Answer:

The correct answer is NO.

Step-by-step explanation:

John is graphing two lines with equations say ax + by + c = 0 and dx + ey +f =0 on his graphing calculator.

For John to get a unique solution the coefficients should follow the following condition $\frac{a}{d} \neq \frac{b}{e}$ . So when he plots the lines he get an intersecting pair of lines.

For John to get no solution the coefficients should follow the following condition $\frac{a}{d} = \frac{b}{e} \neq \frac{c}{f}$ . When we plot in this case we get two parallel lines.

For John to get an infinite many solution the coefficients should follow the following condition $\frac{a}{d} = \frac{b}{e} = \frac{c}{f}$ . And when we plot the lines in this case we get one line superimposed on the other.

Since after graphing, John sees only one line, the lines must have superimposed on one another giving John an infinite number of solutions.

A triangular prism. The rectangular sides are 3 feet by 2 feet, 3 feet by 2.5 feet, and 3 feet by 1.5 feet. The 2 triangular sid

Brrunno [24]

The amount of plywood that he needs to buy will be 21 square feet.

<h3>What is the surface area of the triangular prism?</h3>

Let the prism with a length of L of the rectangular surface.

And the dimension of the triangle is A, B, and C. Then we have

SA = 2(area of triangle) + 3(area of rectangle surface)

A triangular prism.

The rectangular sides are 3 feet by 2 feet, 3 feet by 2.5 feet, and 3 feet by 1.5 feet.

The 2 triangular sides have a base of 2 feet and a height of 1.5 feet.

Then the area of the triangle will be

⇒ 1/2 x 2 x 1.5

⇒ 1.5 square feet

The area of the rectangles will be

⇒ 3 x 2 + 3 x 2.5 + 3 x 1.5

⇒ 18 square feet

Then the surface area of the triangular prism will be

Surface area = 2 x 1.5 + 18

Surface arae = 3 + 18

Surface area = 21 square feet

Answer:

5. A.

6. F

Step-by-step explanation:

5. Perpendicular lines have slopes that are negative reciprocals of one another, so slope is 3

y = 3x + b

using coordinates (-6,3)

3 = 3(-6) + b

b = 21

y = 3x + 21

6. I think F is the right answer
