I don’t know how to do this problem in math

Mathematics

Answer:

142

Step-by-step explanation:

Basically, in f (x) whatever x is will go in the parenthesis.

So,

-(-9)^{2}-7(-9)-2

The two negatives that are next together will turn positive.

9^{2}+63-2

When multiplying two negative numbers turn positive.

9 x 9= 81

81+63-2

144-2=142

Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?
boyakko [2]
Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286

And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)
