I can help if I see the problem
Answer:
6
Step-by-step explanation:
Any circle in the form

Where r^2 is the radius squared, so


Answer: 122°
Step-by-step explanation:
When an angle is supplementary to each other , it means the angle measures to 180°.
Now since one of the two angles is 58°, therefore, the other angle will be
180° - 58°
= 122°
Easy
just find the slope between those 2 points
f(-6)=6
f(-3)=0
slope=rise/run=-6/3=-2
slope is -2
A is answer
X+3≤ -5+2x
Add 5 to the other side. (the inverse of subtraction, since 5 is negative)
x+8≤2x
Subtract x on both sides.
8≤x <- the answer
I hope this helps!
