Answer:
Picture D
Step-by-step explanation:
Sum of angle 1 and angle 2 = 180 as it form a straight line
So, angle 1 and angle 2 are supplementary in picture D
(4x-8x)/2=-2x
4x -(8x/2)=zero
Fist put it in the triangle area formula: A = b * 1/2h
plug in your numbers:
120 = b * 15 or bc you didnt say if it was divided by 1/2 or not i will do both so it could be this too: 120 = b * 7.5 since 7.5 half of 15
solve:
120= b*15
b=8
OR
120=b*7.5
b=16
so 8 or 16 is your answer
depends if 15 was already in half or wasnt
The average rate of change is equivalent to the slope of the graph between the two points.slope = change in y / change in xdy/dx = (-5 - 3) / (2 - 0)dy/dx = -4
The average rate of change from x = 0 to x = 2 is -4.
hope this helps
