Answer:
4x − 30 = ≤12
Step-by-step explanation:
4x − 30 = ≤12
+30 on both sides
4x≤42
divided by 4 on both sides
x≤10.5
Answer:33
Step-by-step explanation: The expressions have equivalent values when x + 6
The expressions have equivalent values for any value of x.
When x=10 , both expressions have a value of 33.

Answer:
Center is (7,-6)
Our radius is 4
Step-by-step explanation:
Subtract 69 to both sides
Complete the square of the x terms and y terms.
(To complete the square divide the coefficient by 2 and square it).
Add those terms to the full equation. Add 36 and 49 to the right side as well
Simplify the x and y terms into a binomial.
Set the left side equal to zero separately to find the center and take the square root of the right side to find the radius.
So our center is (-7,6)
Our radius is 4.
