9(m-2)=m+38
1. Distribute
9m-18=m+38
2. Add 18
9m=m+38+18
3. Simplify
9m=m+56
4. Subtract m from both sides
8m=56
5. Divide by 8 to both sides
m=7
Answer:
x = -25
Step-by-step explanation:
25 = -7(x + 5) + 5x
25 = -7x - 25 + 5x
5x - 7x - 25 = 25
5x - 7x - 25 + 25 = 25 + 25
5x - 7x = 50
-2x = 50
-2x/-2 = 50/-2
x = -25
20. Using absolute value, make (-10) turn into 10 and do 10 + 10 = 20
Answer:
x^2-3x=4
x^2-3x-4=0
x^2-4x+x-4=0
x(x-4)+1(x-4)=0
(x+1)(x-4)=0
x=-1,4
x- intercepts in the point (-1,0) and (4,0)
