Answer:
x=18
Step-by-step explanation:
180=62+(7x-8)
solve
x=18
6x + 4x + 10 = 180
10x = 170
x = 17
mCA = 4(17) + 10 = 68 + 10 = 78
Answer:
mCA = 78°
Answer:
x = 2
Step-by-step explanation:
Multiply both sides by (x-5) and expand:
(x+4)/(x-5)*(x-5) = -2(x-5)
x+4 = -2x+10
Subtract 4 from both sides:
x+4-4 = -2x+10-4
x = -2x+6
Add 2x to both sides:
x+2x = -2x+6+2x
3x = 6
Divide both sides by 3:
3x/3 = 6/3
x = 2
Answer:
1/7.
Step-by-step explanation:
To solve this, we can simply use an equation to solve for the slope using two points:
We can substitute our points giving us:


The slope of the graph is 1/7!
