Answer:
y = 3x + 4
Step-by-step explanation:
Turn the equation from standard form to slope intercept form. So, solve for y.
3x - y = 2
~Subtract 3x to both sides
-y = 2 - 3x
~Divide -1 to everything
y = -2 + 3x
~Reorder
y = 3x - 2
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = 3x - 2
-2 = 3(-2) + b
-2 = -6 + b
4 = b
y = 3x + 4
Best of Luck!
Answer:
x + x+12 + 3(x+12) = 123
x = 15
Step-by-step explanation:
Jamil : x
Kiera : x+12
Luther : 3 ( x+12)
x + x+12 + 3(x+12) = 123
Distribute
x + x+12 + 3x+36 = 123
Combine like terms
5x+ 48 = 123
Subtract 48 from each side
5x+48-48 = 123-48
5x =75
Divide by 5
5x/5 = 75/5
x = 15
