Find the value of r(q(4)), so first you need to find the value of q(4).
q(4), this means that x = 4, so substitute/plug it into the equation to find the value of q(x) when x = 4:
q(x) = -2x - 1 Plug in 4 into "x" since x = 4
q(4) = -2(4) - 1
q(4) = -8 - 1
q(4) = -9
Now that you know the value of q(4), you can find the value of r(x) when x = q(4)
r(x) = 2x² + 1
r(q(4)) = 2(q(4))² + 1 Plug in -9 into "q(4)" since q(4) = -9
r(q(4)) = 2(-9)² + 1
r(q(4)) = 2(81) + 1
r(q(4)) = 163 163 is the value of r(q(4))
Answer: The 8 pound bag
Step-by-step explanation: you divide 9.45 by 5 and you get the unit rate of 1.89 and then you divide 13.68 by 8 and you get the unit rate of 1.71 which means the 8 pound bag is cheaper.

Answer:
4 : 7
Step-by-step explanation:
The ratio of perimeters is exactly the same as the ratio of side lengths. Multiplying each side by 7/4 multiplies the sum of the sides by 7/4.
The ratio of perimeters is 4 : 7.
The best and most correct answer among the choices provided by your question is the third choice or letter C.
<span>If ST = 21, SP = 3b – 11, and PT = b + 4, the value of b would be 14.
