Answer:

Step-by-step explanation:
step 1
Find the equation of the solid line
Find the slope
we have
(0,0.2) and (3,2.2)

The y intercept b is equal to

so
the equation of the solid line in slope intercept form is equal to

step 2
Find the equation of the inequality
we know that
The solution of the inequality is the shaded area below the solid line
therefore

Answer:
d. √(1/(x+1))
Step-by-step explanation:
Just as operations can be performed on numbers and variables, so can operations be performed on functions. Here, you're asked to simplify the ratio of two functions.

At this point, you're supposed to know the factoring of the difference of squares:

Answer:
98, 317, 342
Step-by-step explanation:
Answer:
9x-8 is the simplified form
The radius is 11. I did 7599 divied by 3.14 =2,420. 2,420 divied by 20 and got 121. then i squared that to get 11
