Answer:
2.821
Step-by-step explanation:
To find the point of intersection, you have to set them equal to each other.

To find the y-value, plug in 2 into one of the equations:
y = 2 - 5
y = -3
Point of intersection: (2, -3)
$169, you do 10% and times it 3 times to get 30 then add 9
Answer:
x = 23
Step-by-step explanation:
The marked angles are "corresponding," hence congruent:
8x -27 = 7x -4
x = 23 . . . . . . . . . add 27-7x to both sides
