28°
a triangle = 180°
180°-140°= 40°
180°-68°= 112°
180°-112°-40°= 28°
Answer:
x>-9
Step-by-step explanation:
The given inequality is :
-3x - 7 < 20
We need to find the solution of the inequality using graph.
-3x - 7 < 20
Add 7 to both sides
-3x-7+7 < 20+7
-3x <27
x>-9
Hence, the attatched graph shows the solution of the given inequality.
Answer:
D. 20%
Explain:
30-25=5
5/25= 20%
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
Please consider marking brainliest :) I can correct mistakes if needed.
18. The shape is only shifted to a different location and orientation but remains the same size so this is congruent.
19 and 20 are both scaled to a different size so they are both similar.
