1. -88 = -3(4m + 5) - (1 - 3m)
1 answer:
Answer:
m=8
Step-by-step explanation:
-88=-3(4m+5)-(1-3m)
-88=-12m-15-(1-3m) <- Distributive Property
-88=-12m-15-1+3m <- Open () if there is a negative negative the symbol equals positive
-88=-9m-16 <- Simplify
0=-9m+72 <- Add 88 to both sides
9m = 72 <- Add 9m to both sides
9m = 72
/9 /9
m=8

Step-by-step explanation:
Answer:
x=±9 and y=10
Step-by-step explanation:
so for x
we have
x²+(-4)=32
x²=36
x=±9
for y:
y+y-4=y+6
2y-4=y+6
y=10
Answer:
y+7=5/4(x-8)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-7)=5/4(x-8)
y+7=5/4(x-8)
The y intercept is (0,-5)
The maximum is at (3,4)
There are two real solutions (roots)
