The inver of given function will be (1,-3).
Answer:
4
Step-by-step explanation:
So we know that RT is 36.
Note that RT is the combined length of RS and ST. Therefore:

Substitute. RT is 36, RS is 6x+1 and ST is x+7:

Combine like terms and add:

Subtract 8 from both sides:

Divide by 7:

So, our answer is 4 :)
Answer: There were 89 retail stores in 1997.
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the number of years since 1990(x).
1997-1990 = 7 years
Now, we simply substitute x=7 (years) in the equation given
y=11x+12
y=11(7)+12
y=77+12
y = 89 retail stores
There were 89 retail stores in 1997.

Answer:
-2 < x < 4
Step-by-step explanation:
This inequality has 3 sides.
Lets ADD 4 to all sides:
-8 < 2x - 4 < 4
+4 +4 +4
-4 < 2x < 8
Now we divide all sides by 2, to get:
-4 < 2x < 8
-4/2 < 2x/2 < 8/2
-2 < x < 4
The inequality is solved. To the value of x ranges from x = -2 to x = 4. This is the answer.
