Answer:
1.2
Step-by-step explanation:
1.2 is answer but you can simplify to 1 1/5
<span>Equation at the end of step 1 :</span> (8x + 2 • (x - 7)) - (10x - 14) = 0
<span>Step 2 :</span>Pulling out like terms :
<span> 2.1 </span> Pull out 10x-14
After pulling out, we are left with :
(10x-14) • ( 1 +( (-1) ))
<span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
10x - 14 = 2 • (5x - 7)
<span>Equation at the end of step 3 :</span> 0 = 0
Answer:
a. -2 b. -2 c. -1 d. 4 e. -3 f. 0
Step-by-step explanation:
The average rate of change formula is:

a.
We need to find the rate of change for x = -3 to x = -2 so we look on the graph to find y.
At x = -3 it look like y = 0 so


At x = -2 it looks like y = 2


Now we can just plug everything in to the rate of change formula.
= -2
So for a. our rate of chage for the given interval is -2
b.
Now that you have the formula we don't need to explain each time.
-2
2
1
- 4
= -2
c.
0
-3
1
- 4
= -1
d.
1
-4
2
0
= 4
e.
-1
0
0
-3
= -3
f.
-1
0
2
0
= 0
Radius = 3 units
Using pi as 3.132
Area of circle =

= 3.142 x 3 x 3 = 28.278 square units ≈ 28.28 square units
OR if you use the calculator and press pi x 3 x 3 = 28.27square units
