Accepted Answer

9x + 4y = 13

Accepted Answer

x + y = 10

Answer

3x - y = 6

Answer

3x - y = 2

Answer

4x + 9y = 36

Question 3

A customer paid a total of $6.00 for 68 copies at a print shop. Some of the copies were black-and-white copies, and the rest were color copies. Each black-and-white copy cost $0.08. Each color copy cost $0.15. Which system of equations can be used to find $ b $, the number of black-and-white copies, and $ c $, the number of color copies that the customer paid for at the print shop?

Choose TWO correct answers.

Accepted Answer

b + c = 68

Accepted Answer

0.08b + 0.15c = 6.00

Answer

b + c = 6.00

Answer

0.15b + 0.08c = 6.00

Answer

0.08b + 0.15c = 68

Question 4

The graph of linear function g passes through the points (-7, -4) and (7, 6), as shown. What are the slope and y-intercept of the graph of g?

Accepted Answer

The slope is $$\frac{5}{7}$$ , and the y-intercept is 1.

Answer

The slope is $$\frac{5}{7}$$ , and the y-intercept is -1.

Answer

The slope is $$\frac{7}{5}$$ , and the y-intercept is -1.

Answer

The slope is $$\frac{7}{5}$$ , and the y-intercept is 1.

Question 5

What is the equation in standard form of the line that passes through the point (6, -1) and is parallel to the line represented by 8x + 3y = 15?

Accepted Answer

8x + 3y = 45

Answer

8x + 3y = -45

Answer

8x - 3y = -51

Answer

8x - 3y = 51

Question 6

What is the equation in slope-intercept form of the line that passes through the point (2, -2) and is perpendicular to the line represented by $$y=\frac{2}{5}x+2$$ ?

Accepted Answer

$$y=-\frac{5}{2}x+3$$

Answer

$$y=\frac{5}{2}x-7$$

Answer

$$y=\frac{5}{2}x+7$$

Answer

$$y=-\frac{5}{2}x-3$$
