Answer:
y/x = R
Step-by-step explanation:
The two quantities x and y are proportional means they have a relation.
The equation is;
y= Rx ------to find the proportional R you make R the subject of the formula;
y/ x = R
To find the answer you have to divide 5,631.72 by 71. the answer is 79.32, so she traveled 79.32 kl.
hope it helped ^-^
F(5) is like X is 5
you just do this
f(5)=-2x+1
=-2(5)+1
=-10+1
= -9

Answer:

Step-by-step explanation:
The given function are;
f(x) = x² - 3·x - 12, and g(x) = -x - 12

Therefore;

g(-8) = -(-8) - 12 = 8 - 12 = -4
∴ f(g(-8)) = f(-4) = (-4)² - 3×(-4) - 12 = 16
Therefore;
