Write the equation in
standard
form for the circle with center (-8, -1) and radius 4.

1+1=22×1=22-1=11-1=1duh

The right answer should be 6 but your not very specific

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
