Answer:
-5 - h
Step-by-step explanation:
ƒ(x) = 1 + 5x - x²
[f(5 + h) -f(5)]/h
= [1 + 5(5 + h) - (5 + h)² - 1 - 5(5) +5²]/h
= (25 + 5h - 25 - 10h - h² - 25 + 25)/h
= (-5h - h²)/h
= -5 - h
The difference quotient is -5 - h.
Answer:
D. 2.
Step-by-step explanation:
Using the points (1,3) and (-1,-1):
The slope= (3 - -1) / (1 - -1)
= 4/2
= 2.
The two points are on the same line on the x-axis, so to find the length we need to find the distance between the points on the y-axis. Subtract one y from the other (it doesn't matter which) and take the absolute value. 18 - (-7) = 25. The absolute value of 25 is 25. The length of that side of the rectangle is 25.
