Answer:
m+n=140
Step-by-step explanation:
So the angles in a triangle always add up to 180. We already know that the first angle in the triangle is 40 degrees because it's shown in the angle below the triangle. So we have 140 degrees left since 40 is taken up. That eans m+n=140

Answer:
<h2>
f(x) = -²/₅ x - ¹⁷/₅</h2>
Step-by-step explanation:
The equation of the linear function: f(x) = mx + b
f(-1) = -3 ⇒ -3 = m(-1) + b ⇒ m = b + 3
f(4)=-5 ⇒ -5 = m×4 + b
-5 = 4(b+3) + b
-5 = 4b + 12 + b
5b = -5 - 12
b = -¹⁷/₅
m = -¹⁷/₅ + 3 = -¹⁷/₅ + ¹⁵/₅ = -²/₅
Therefore the function:
<h3>
f(x) = -²/₅ x - ¹⁷/₅</h3>
