Answer:
u^2 +7u -8=0 where u = 3x+2
Step-by-step explanation:
(3x+2)^2 + 7(3x+2) - 8=0
Let 3x+2 = u
u^2 +7u -8=0
If you would like to calculate 2/7 * 35, you can do this using the following steps:
2/7 * 35 = 2 * 35/7 = 2 * 5 = 10
The correct result would be 10.
M = (y2 - y1) / (x2 - x1)
1/4 = (5-3) / (r +4)
1/4 = 2/ (r + 4)
Cross multiply
2*4 = r + 4
8 = r + 4
Subtract 4 from both sides
4 = r
CHECK
(-4,3)(4,5)
m = (5-3)/(4--4) = 2/8 = 1/4
