Where you see x, you would substitute for -1. f(-1)= 2(-1) + 2. f(-1)= -2 + 2 =0
Answer:
percent: a specified amount in or for every hundred.
example of percent:
For example, 1 percent of 1,000 chickens equals 1/100 of 1,000, or 10 chickens; 20 percent of the quantity is 20/100 1,000, or 200.

Answer:
The radius is 5 in
Step-by-step explanation:
The area of a circle is given by the formula
A = pi *r^2
We know the area = 78.5 in^2 (volume would be in^3 area is in^2)
78.5 = 3.14*r^2
Divide each side by 3.14
78.5/3.14 = 3.14/3.14*r^2
25 = r^2
Take the square root of each side
sqrt(25) sqrt(r^2)
5 =r

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
0.8k - 20 = -60
<u>Step 2: Solve for </u><em><u>k</u></em>
- [Addition Property of Equality] Add 20 on both sides: 0.8k = -40
- [Division Property of Equality] Divide 0.8 on both sides: k = -50
Answer:
-2x + 6 8x or 5x + 3 < 9
Step-by-step explanation:
-2x + 6 8x -> x 3/5
5x + 3 < 9 -> x < 6/5
