y = 3x + -9 + 8x
Reorder the terms:
y = -9 + 3x + 8x
Combine like terms: 3x + 8x = 11x
y = -9 + 11x
Solving
y = -9 + 11x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.

Answer:
145
Step-by-step explanation:
Because that angle(C) is sum of the A & B. ✌️
Answer:
Of two numbers, The largest whole number which is a factor of both.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
First create the equation that has slope of -1 in the form of y=mx+b. Because the slope is -1, m=-1, so the equation is y=-x+b. Now we see that we are given the point (-3, 8) as an intersection point. Substitute x and y for -3 and 8 in our equation. With this information, our equation becomes 8=3+b. Solving, b=5. Our equation is now y=-x+5.
Simplifying all of the answer choices, we have
A. y=-x-5
B. y=-x+5
C. y=-x-5
D. and E. as what they already show
The only answer that matches is B.
