$y =f(x) = - 2x + 4$

_________________________________

$f( - 4) = - 2( - 4) + 4$

$f( - 4) = 8 + 4$

$f( - 4) = 12$

_________________________________

$f(0) = - 2(0) + 4$

$f(0) = 0 + 4$

$f(0) = 4$

_________________________________

$f(5) = - 2(5) + 4$

$f(5) = - 10 + 4$

$f(5) = - 6$

_________________________________

Range = { 12 , 4 , -6 }

Thus the correct answer is (( A )) .

a scale drawing of a bus has a scale of 1/2 inch to 5 feet. If the length of the school bus is 4 1/2 inches on the scale drawing

TEA [102]

Let x feet be the actual length of the school bus. You know that in a scale drawing

$\dfrac{1}{2} \text{ inch } - 5 \text{ feet},$

then

$4\dfrac{1}{2} \text{ inch } - x \text{ feet}.$

Write a proportion:

$\dfrac{\frac{1}{2}}{4\frac{1}{2}}=\dfrac{5}{x}\Rightarrow x=\dfrac{5\cdot 4\frac{1}{2}}{\frac{1}{2}}=\dfrac{5\cdot \frac{9}{2}}{\frac{1}{2}}=\dfrac{\frac{45}{2}}{\frac{1}{2}}=\dfrac{45}{2}\cdot \dfrac{2}{1}=45\text{ feet.}$

Answer: the actual length of the school bus is 45 feet.
