Answer:
A
Step-by-step explanation:
1 divide by 15
Answer: x = 17
Step-by-step explanation: combine all of those numbers.
3x+x+22.
Combine like terms, so
4x + 22 = 90 (90 is the sum of 2 complementary angles)
Subtract 22 from both sides to get
4x = 68
Now divide by 4 to get x which is
x = 17
There would be two more Xs above the 3
Y = 4x - 19...slope here is 4...parallel lines will have the same slope
y = mx + b
slope(m) = 4
(0,7)...x = 0 and y = 7
now sub
7 = 4(0) + b
7 = b
so ur equation is : y = 4x + 7
