This is a square root meaning whatever number multiplied by itself equals it’s square root. The answer would be 4 on the outside and 3 on the inside
-2x + 5 < 7
-2x + 5 < 7
<u> -5 -5 </u> deduct 5 from both sides
-2x < 2
<u>÷ -2 ÷ -2 </u> divide both sides by negative 2. Because of the division
x > -1 using a negative number, the sign is then reversed.
from < it becomes >.
The value of x should be greater than -1. It can be 0, 1, 2, so on...
To check: Revert back to the original sign which is <.
x = 1
-2x + 5 < 7
-2(1) + 5 < 7
-2 + 5 < 7
3 < 7

Answer: 1.5
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
- Find a point on the line where it touches a gridpoint and start from there. Slope is defined as rise/run, so from that point you either go up or down for rise, and left or right for run to find another point closest where the line touches a gridpoint.
- A graph with a slope that looks like \ will be negative and a slope that looks like / will be positive
5. 3/2
6. Undefined
7. 7/2
8. 3/6 simplifes to 1/2
9. -1/3
10. -2/3
