Answer:
43y
Step-by-step explanation:
31y+12y
combine like terms
Factor out y
y( 31+12)
y (43)
43y
The attached image is the graph.
2 figures are congruent if at least 2 sides are the same length, there angles are the same, etc
Answer:
y = -2x + 5
Step-by-step explanation:
Assuming this is linear, the slope would be constant. For every 1 x, y decreases by 2. This means that the slope is -2.
y = -2x + b
Now all we need is the y-intercept.
If we plug in the first point (1,3), we get:
3 = -2*1+b
3 = -2+b
b = 5
This is the y-intercept.
y = -2x + 5
Alternate exterior angles(AEA).
Given their relationship the angles are congruent.
8x-71=5x+7
3x-71=7
3x=78
X=26
