Answer:
c. -17
Step-by-step explanation:
We have the function f(x) = -2t^2 + 1 and we need to solve for x if f(-3).
Substitute the x in the function with the x in the equation :
f(-3) = -2(-3)^2 + 1
Solve for the answer :
f(-3) = -2(9) + 1
f(-3) = -18 + 1
f(-3) = -17
Therefore, c. -17 is the answer.
Answer:
$105.25
Step-by-step explanation:
First we need to know to price of the blender after the sale, so we are going to pay the 88% of the blender's price so the final price without the sale tax is going to be
(1)
Knowing this price we need to calculate the 8% of the total price
(2)
We substract the result (2) from (1)

Rounding this number to nearest cent the final result is:
$105.25
Factoring the expression would be 6a(2a^2+4a-1)
