Answer:
Choice A.
Step-by-step explanation:
Slope intercept form of equation is y = mx + b where m is slope and b is y intercept. You can see from diagram that y intercept is -3, and if you count rise/run for slope you go up 2 over 1 so the slope is 2.
Answer:
28
Step-by-step explanation:
Mikhail's age:x

3x=84
x=84÷3
x=28
Answer:
B. 7y - 15
Step-by-step explanation:
Simplifying
10y + -3(y + 5) = 0
Reorder the terms:
10y + -3(5 + y) = 0
10y + (5 * -3 + y * -3) = 0
10y + (-15 + -3y) = 0
Reorder the terms:
-15 + 10y + -3y = 0
Combine like terms: 10y + -3y = 7y
-15 + 7y = 0
Solving
-15 + 7y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 7y = 0 + 15
Combine like terms: -15 + 15 = 0
0 + 7y = 0 + 15
7y = 0 + 15
Combine like terms: 0 + 15 = 15
7y = 15
Divide each side by '7'.
y = 2.142857143
Simplifying
y = 2.142857143
Answer:
m=8+3n
Step-by-step explanation:
Move all terms that don't contain m to the right side and solve.
Hope this helps <3
0.7 is 0.07 times ten, and 0.7 times 10 is 7 :)
