Because we're given two points on the line, we can apply the slope formula to find the answer:
-4 - 8 / 2 - (-1)
-12 / 3
-4
<h3>The slope of the line is -4.</h3>
The 3 angles of a triangle have to add up to 180 degrees. Since we are given 2 of the angles, all we have to do is add them up and then subtract from 180 to get the 3rd.
112 + 41 = 153
180 - 153 = 27
Angle 2 = 27 degrees.
A. this is not a function because x=1 has 2 outputs So does x=3
B . f(120) = 20 + 10*120 = 1220
This is the cost in dollars of renting a boat for 120 hours.
