Answer:
8
Step-by-step explanation:
Because 16 is the diameter and to find the radius you need to divide by 2
The other endpoint is (1, -17).
The midpoint formula is:

Using our midpoint and endpoint, we have:

For the first equation (to find the x-coordinate) we will multiply both sides by 2:

Subtract 11 from both sides:
12 - 11 = 11+x₂ - 11
1 = x₂
For the second equation (the y-coordinate) we multiply both sides by 2:

Add 5 to both sides:
-22+5 = -5+y₂ + 5
-17 = y₂
This means that (x₂, y₂) is at (1, -17).
Answer:
(-4, -5)
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
both sides are equal
both sides have to match
therefore y is 90 and x is 30
it is a symmetry thing
The solution to the system of equation is x ≤ –4 and x > 4
<h3>Compound inequality</h3>
Given the inequality expression
2x ≤ –8 or 3x + 1 > 13
Solving individually
2x ≤ –8
Divide both sides by 2
2x/2 ≤ –8/2
x ≤ –4
For inequality 3x + 1 > 13
3x > 13 - 1
3x > 12
x > 12/3
x > 4
Hence the solution to the system of equation is x ≤ –4 and x > 4
