To find f(-7), just plug -7 in for all x
2(-7) + 8
-14 + 8
-6 is the answer!
The correct answer to this question is that the cheetah can run 369,000
feet per hour. We can work this out in the following way:
One mile equals 1760 yards
In feet that is 3 x 1760 or 5,280
So Feet per hour will be 5280 x 70 or
369,600 feet per hour.
Answer:

More than 6.8 yards per game.
Step-by-step explanation:
Let x be the possible number of yards per play for the winning team.
We have been given that the winning team had 80 offensive plays, so the number of possible yards in 80 offensive plays will be 80x.
We have been given that a winning football team more than doubled the offensive yards gained by its opponent.
We can represents this information in an inequality as:

Therefore, the inequality
can be used to find the possible number of x of yards per play for the winning team.
Let us solve for x.

Let us divide both sides of our inequality by 80.


Therefore, the winning team will score more than 6.8 yards per play.
