Answer:
A. 2
Step-by-step explanation:
When you don't know if a number like 256 is a power of anything, it can work reasonably well to start by simply dividing by the factors you know.
- 256/2 = 128
- 128/2 = 64
- 64/2 = 32
- 32/2 = 16
- 16 = 2^4, so 256 = 2^4 · 2 · 2 · 2 · 2 = 2^8
The 8th root of 2^8 is 2, choice A.
The answer is greater than because
63.2 divided by 0.8 is 79
Solve each inequality by itself.
2x - 6 < -12 and 3x + 5 > -13
Add 6 to both sides Subtract 5 from both sides
2x < -6 and 3x > -18
Divide both sides by 2 Divide both sides by 3
x < -3 and x > - 6
You can write the solution as
x > - 6 and x < -3
To graph, draw a number line.
Place an open dot on -6.
Place an open dot on -3.
Draw a wide, dark line from one dot to the other dot.
