What they want here is the slope of the line through (1,7) and (-3,9)

Using the slope formula, we get...

m = (y2-y1)/(x2-x1)
m = (9-7)/(-3-(-1))
<span>m = (9-7)/(-3+1)</span>
m = 2/(-2)
m = -1

So the answer must be choice D) -1

If you draw a line through these two points, the line will slope downward (move from left to right). Each time you go down 1, you go to the right 1.

Answer:

The correct option is 4. The average rate of change from x = −1 to x = −3 is -1.

Step-by-step explanation:

It is given that the graph of parabola going through (-1,7) and (-3,9).

It means the value of at x=-1 is 7.

f(-1)=7

The value of at x=-3 is 9.

f(-3)=9

The slope of a function f(x) for the interval [a,b] is

m=\frac{f(b)-f(a)}{b-a}

We have to find the average rate of change from x = −1 to x = −3. Here a=-1 and b=-3. So the average rate of change from x = −1 to x = −3 is

m=\frac{f(-3)-f(-1)}{-3-(-1)}

m=\frac{9-7}{-3+1}

m=\frac{2}{-2}

m=-1

The average rate of change from x = −1 to x = −3 is -1. Therefore the correct option is 4.

The Quotient 250 divided by 5/8 tells about how far a sloth may move in one hour How far can a sloth go in 90 minutes?
Hunter-Best [27]

Given condition is:

A sloth moves in one hour = \frac{250}{5/8}

\frac{5}{8}=0.625

So, a sloth moves in one hour = \frac{250}{0.625}=400 units

Hence, in 60 minutes a sloth moves = 400

In 1 minute sloth will move = \frac{400}{60}

In 90 minutes it will  move = \frac{400}{60}\times90=600

The answer is 600 units.
