add all the numbers until u left with no numbers left except the number left over and then add xs and then subtract the number from 23 to isolate x. then divide x by the number left over from the right side.
-6+9-19=-16
x+2x=3x
so -16+3x= 23
+16 +16
3x=39
(3/3)x=39/3
x=13
hope it helps!
Y<-60
hope this helps and good luck;)
For this case we have the following function:

For each of the domains we will choose a value.
We have then:
For −5 ≤ x ≤ −1
Let's choose the value of x = -3
Evaluating the function we have:
Answer:
g(-3) = 1
For −1 < x ≤ 5:
Let's choose the value of x = 0
Evaluating the function we have:
Answer:
g(0) = 2
1 mile is equal to 1.6 kilometers, so 8 miles (using a direct proportion) should be equal to 8 * 1.6 = 12.8 kilometers. The cyclist rides at 12.8 kilometers per hour. In four hours, the cyclist would have rode 12.8 * 4 = 48 + 3.2 = 51.2 kilometers.
