Answer:

The average rate of change is 2.

Step-by-step explanation:

We are given the function:

g(x)=-x^2+x+5

And we want to find the average rate of change over the interval:

-4\leq x\leq 3

The average rate of change is synonymous with the slope. So, we will evaluate the function at its endpoints and find the slope between them.

Our first endpoint is given by:

g(-4)=-(-4)^2+(-4)+5=-15

And our second endpoint is given by:

g(3)=-(3)^2+(3)+5=-1

This gives us two points (-4, -15) and (3, -1). The average rate of change will be the slope between them. Thus:

\displaystyle ARC=\frac{-1-(-15)}{3-(-4)}=\frac{14}{7}=2

The average rate of change is 2.

Use the drop-down menus to complete each equation so the statement about its solution is true.
disa [49]

Answer:


Step-by-step explanation:

So,it would be easier to simplify the right equation, so when I say "the right equation", I mean the one I will make right now. It is 8x+9. So the first problem is 8x+9=x+?. Well, if there are no solutions, the slopes have to be the same, and the y-int doesn't matter. So the answer would be + 7x because that will make the x an 8x. If there is one solution, then the slope has to be different. So literally anything but 7x will work. Even constants. If there are infinitely many solutions, then the equations have to be the same. Meaning, you would have to add 7x and 9 to make the left equation the same as the right.

Find the distance between (5, -2) and (7, -2)
Nuetrik [128]

Answer:

The distance is (2, 0)

Step-by-step explanation:

The first number is on the X axis. You move forward two places to get 7. The second number is on the Y axis, and you don't need to move anything so it stays the same. Hence the answer is a distance of two on the X axis.
