Answer:
Ummm ok?
Step-by-step explanation:
Where’s the question?
Answer:
x=21
Step-by-step explanation:
Following the vertical angles, we can assume that the equation that has x and 87 are equal to each other. From then, you set them equal to each other and solve for x.
87=4x+3
84=4x subtract 3 from both sides
21=x divide by 4 to get the x alone on both sides
The answer is 2
Because 2-3=-1
Answer:
(1/2)x - y = -2

Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Standard Form: Ax + By = C
Step-by-step explanation:
<u>Step 1: Define equation</u>
Slope-Intercept Form: 2 + (1/2)x = y
<u>Step 2: Find Standard Form</u>
- Rewrite: y = (1/2)x + 2
- Subtract 1/2x on both sides: y - 1/2x = 2
- Factor negative: -(1/2x - y) = 2
- Divide both sides by -1: 1/2x - y = -2
