Answer:
I think its 245 but i'm not sure
Step-by-step explanation:
Two angles are complementary when they add up to 90° ⇒
∠A + ∠B = 90°
3x + 5 + 2x - 15 = 90
5x - 10 = 90
5x = 90 + 10
5x = 100
x = 100/5
x = 20
<span>m∠A = 3x + 5 = 3*20 + 5 = 60 + 5 = 65</span>°<span>
</span><span>m∠B = 2x - 15 = 2*20 - 15 = 40 - 15 = 25</span>°<span>

Answer:
y = 7x +2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (- 1, - 5 )
m = = = 7
the line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = 7x + 2 ← equation of line
