G(x)=-f(x)-2
x=-2→g(-2)=-f(-2)-2=-(-1)-2=1-2→g(-2)=-1
x=-1→g(-1)=-f(-1)-2=-(1)-2=-1-2→g(-1)=-3
x=0→g(0)=-f(0)-2=-(3)-2=-3-2→g(0)=-5
x=1→g(1)=-f(1)-2=-(5)-2=-5-2→g(1)=-7
x -2 -1 0 1
g(x) -1 -3 -5 -7
Answer:
$60
Step-by-step explanation:
2 T-shirts = $15
Longer version
15/2 = $7.50
1 T- shirt = $7.50
7.50*8 = $60
Short version
2 T-shirts = $15
bought 8 so 8/2 = 4
4*15= 60
The answer to your question is 64.
Let x = the width
then
2x = the length
:
The box dimensions: 2x by x by 4
Given the surface area:
2(2x*x) + 2(2x*4) + 2(x*4) = 220
:
4x^2 + 16x + 8x = 220
A quadratic equation:
4x^2 + 24x - 220 = 0
simplify, divide by 4
x^2 + 6x - 55 = 0
Factor
(x+11)(x-5) = 0
The positive solution is what we want here:
x = 5 ft is the width
then
2(5) = 10 ft is the length
:
Find the volume
10 * 5 * 4 = 200 cu/ft is the volume
-1 would be your answer. f(0) = -4. f(1) = f(0)+3 so f(1) = -1
