4x + y = 12
Get y by itself
Subtract 4x
y = -4x + 12
Since you know what y is, you can plug the value into the second equation
6x + 2(-4x + 12) = 18
6x - 8x + 24 = 18
-2x = -6
x = 3
Plug the value 3 into x for y = -4x + 12 in order to find y
-4(3) + 12 = y, y = 0
Solution: x = 3, y = 0
B is equal to 51 because angles in a right angle add up to 90
Answer:
Step-by-step explanation:
Answer:
y = 1/2x + 2
Step-by-step explanation:
y = mx+b, where m is the slope, b is y-int, and y and x are variables.
Step 1: find the y-int: 2. Using this you can out rule C and D.
Step 2: find the RISE/RUN: 1/2. This is your slope.
Step 3: fill in your equation.
Hope that helps
