Question 7

A city employee paints curbs in parking lots and replaces road signs. It takes 0.5 hour to paint a parking lot curb and 2.5 hours to replace a road sign. The function below can be used to find c, the number of parking lot curbs the employee paints when he replaces r road signs in a 40-hour workweek.

c = $\frac{40 - 2.5r}{0.5}$

If the employee painted 20 curbs in one week, how many road signs did he replace that
week?

Question 10

Which statement about
k(x) = -x$^2$ - 2x + 15 
is true?

Accepted Answer

The zeros are -5 and 3, because k(x) = - (x + 5)(x - 3).

Answer

The zeros are 3 and 5, because k(x) = -(x - 3)(x - 5).

Answer

The zeros are -5 and -3, because k(x)= - (x + 5)(x + 3).

Answer

The zeros are -3 and 5, because k(x) = -(x + 3)(x - 5).

Question 11

Which statement about f(x) = 2x$^2$ - 3x - 5 is true?

Accepted Answer

The zeros are -1 and $\frac{5}{2}$, because f(x) = (x + 1)(2x - 5).

Answer

The zeros are -$\frac{5}{2}$ and -1, because f(x) = (x + 1)(2x + 5).

Answer

The zeros are 1 and $\frac{5}{2}$, because f(x) = (x - 1)(2x - 5).

Answer

The zeros are -$\frac{5}{2}$ and 1, because f(x) = (x - 1)(2x + 5).

Question 12

Which statement about $g(x) = x^2-576$ is true?

Accepted Answer

The zeros, $-24$ and $24$, can be found when $0 = (x + 24)(x-24)$.

Answer

The only zero, $24$, can be found when $0 = (x-24)^2$

Answer

The only zero, $288$, can be found when $0 = (x-288)^2$.

Answer

The zeros, $-288$ and $288$, can be found when $0$ = $(x+288)(x-288)$.
