Answer:
wanna help, but please specify what the (2) means.
our take a picture of the problem and makes me post.
Answer:
y = 3x + 7
Step-by-step explanation:
Parallel lines have the same slope, so you can write the equation y = 3x + b and you have to figure out what b is.
plug in x = -3 and y = -2 into the equation y = 3x + b:
-2 = 3 * -3 + b
-2 = -9 + b
7 = b
So the equation is y = 3x + 7
Answer:
b=4a
Step-by-step explanation:
Answer:
x ≈ 73.3
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos39° = 
= 
( multiply both sides by x )
x × cos39° = 57 ( divide both sides by cos39° )
x = 
≈ 73.3 ( to the nearest tenth )
