Answer:
d) not proportional
Step-by-step explanation:
the rate of change between the first two pairs of x-and-y values is 12/3, between the second pair it is 21/3, and 15/3 between the last pair
4, 7, and 5 are all different values so there is not one constant of proportionality
Answer: 16x/75 - 12/35

Answer:
13/1*7/4
Step-by-step explanation:
The way you get this is by using the Keep, Change, Flip Method. 13 as a fraction would be 13/1, and this is the keep phase. The change phase is where you change division to multiplication. The flip phase is when we flip the numerator and denominator. Remember, this only works when dividing fractions.
Answer:
yep
Step-by-step explanation:
yes always
Answer: 
Step-by-step explanation:
f(x) = -3x² - 6x
<u>Requirements of the question</u>
Find the value of f(-9)
<u>Substitute values into the given function</u>
f(x) = -3x² - 6x
f(9) = -3 (-9)² - 6 (-9)
<u>Simplify the exponent</u>
f(9) = -3 (81) - 6 (-9)
<u>Simplify by multiplication</u>
f(-9) = (-243) - (-54)
<u>Simplify by subtraction</u>
