Answer:
Assuming that Janet spent an equal amount of time on each question, he would have spent 75 seconds on each question.
Step-by-step explanation:
10 minutes = 600 seconds
600 seconds / 8 questions = 75 seconds.
X is 38, y is 27.
This is because you are subtracting on the 90 degree angles.
gradient:
3x+2y=5
3(1)+2dy/dx=0
3+2dy/dx=0
2dy/dx=-3
dy/dx=-3/2.
y-intersect:
2y=5-3x
y=5-3x/2
8/9
The equation to find a slope is y2-y1/x2-x1=m. (m is the slope)
174-166/173-164
So the slope is 8/9.
≈5.61
