The two angles are vertical angles so they are congruent.
3x+18=5x
2x=18
x=9
21+3x=-15
3x=-15-21
3x=-36
x=-36/3
x=-12
2/6 because 1×2=2 and 3×2=6 ...but whatever you multiply to one side you have to multiply to the other side
Answer:
14 7/12
Step-by-step explanation:
You take 6 3/4 and subtract 1/2 cup, which equals 6 1/4. Then you take 6 1/4 and divide that by 3. Then you multiply that answer (2 1/12) by seven.
X1=-2 and x2=0
We need to find y1 and y2 so
F(-2)=2^(-2+2)+1=2
The point(x1,y1)=(-2,2)
F(0)=2^(0+2)+1=5
The point(x2,y2)=(0,5)
Now, calculate the average rate of change (slope):
m = (y2 – y1) / (x2 – x1) =(5-2)/(0-(-2))
m=3/2
The answer is c
