Answer:
b or d
Step-by-step explanation:
Yes, so the Y intercept of the linear regression line is 250 ( it is on the y-axis at point [0,250]. You can also see that for every 2x the number on the y axis decreases by 50. This means that the slope is -25. Now put what we know into the equation for a line - y=mx+b
y = -25x +250
Two angles are complementary when they add up to 90 degrees<span>
</span>Two angles are supplementary when they add up to 180 degrees
angle = x
supplementary angle = (180-x)
complementary angle = (90-x)
180 - x - 40 = 2(90-x)
140 - x = 180 - 2x
-x + 2x = 180 - 140
x = 40°
The answer is an Equilateral Triangle. I believe.
