21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6
Answer:
Step-by-step explanation:
4
Answer:
y = 4/3x - 2, B is your answer
Step-by-step explanation:
Y intercept is the number next to slope(b).
The co efficient of x will be your slope so therefore the co efficient of x will be 4/3
y is always there because it will always be the dependent variable on the left side.
Vertex is (-3 , 21 ) you can put <span>y=-2x^2-12x+3 in google and you will see the function</span>
Answer:
8
Step-by-step explanation:
3(8-m)=5m-40
you first distribute 3 through the parenthesis
24-3m=5m-40
Move the variable to the left and change sign
24-3m-5m=-40
now move the constant to the right
-3m-5m=-40-24
collect like terms
-8m=-40-24
-8m=-64
Divide both sides by -8 and negative divide negative number becomes positive
so m = 8
