Answer:
Simplifying 9m + -3 + -7m = 0
Reorder the terms: -3 + 9m + -7m = 0
Combine like terms: 9m + -7m = 2m -3 + 2m = 0 Solving -3 + 2m = 0
Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right.
Add '3' to each side of the equation. -3 + 3 + 2m = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2m = 0 + 3 2m = 0 + 3 Combine like terms: 0 + 3 = 3 2m = 3
Divide each side by '2'. m = 1.5

Answer:
X=5
Step-by-step explanation:
You want to factor the left side of the equation
(X-5)(x-5)=0
Set factors that will equal to 0
X-5=0
X=5 is the answer
Answer:
Y-intercept
Step-by-step explanation:
3 if by the x axis 4 if by the y axis
Use the data in the given table for #4 to find the slope of the line through these four points. I did this this way:
5-3 2
m = -------- = ---- = 1/2
12-8 4
Now use y = mx + b to determine the y-intercept:
Borrowing the coefficients (0,0) from the table,
0 = (1/2)(0) + b. Thus, b = 0, and y = (1/2)x (answer)
