Answer: It’s A y > x^2-4
Y < x^2+3
Step-by-step explanation:
Answer:
for the first one, simply add g(x) and h(x) :
x+3 + 4x+1 = 5x + 4
the second one, you would multiply them :
(x+3)(4x+1) = 4x^2 + 13x + 3
the last one, you would subtract :
(x+3)-(4x+1) = -3x + 2
and then substitute 2 for 'x' :
-3*2 + 2 = -6 + 2 = -4
Unfortunately, you haven't shared the instructions for this problem. My guess is that you are to evaluate <span>P(x)= x^3+4x^2-8x-6 for x = a = -2.
If that's the case, then
P(-2) = (-2)^3 + 4(-2)^2 - 8(-2) - 6. This simplifies to:
= -8 + 16 + 16 - 6 = 18 (answer)</span>
Let's think about what happens when you find the price after tax. Let the price before tax be
. The tax rate is
, so the tax part of the total price is
. Adding that onto the original price, we see that
So, we can just divide each side by
to get the original price, which rounded to two decimal places is
.
