The y intercept is positive three because if you solve for y then you get y=-2x+3 and the positive three is the y intercept
Step-by-step explanation:
- m <a+m <b+m <c=180 {sum of angles in a straight line are 180}
- 3x+5+5x-18+7x-2=180
- 15x-15=180
- 15x=180-15
- 15x=165
- x=165/15
- x=11
- so, m<a=3x+5=3×11+5=33+5=38
m<b=5x-18=5×11-18=55-18=37
m <c=7x-2=7×11-2=77-2=75
part B: no bcuz their sum isn't 90 whereas to be complement it must be 90
The 8th term would be 8.25 because it decreases by .25 each term. 10,9.75, 9.5, 9.25, 9, 8.75, 8.5, 8.25
No picture was attached. Sorry.
Answer:
8mph
Step-by-step explanation:
Let call X is trip there speed
R x t = D
# to X 3 = 3X
# Return 6 4 = 24
Because the distance when we go to and back are the same, so we have:
3X = 24
<=> X = 8
So the avergage speed of the trip there is 8mph
