Answer:
(x + 1)² + (y - 4)² = 25
Step-by-step explanation:
The general equation for a circle is given by the formula;
x² + y² + 2hx + 2ky + c = 0 ......equation 1.
Where the center is C(-h, -k)
Also, the standard form of the equation of a circle is;
(x - h)² + (y - k)² = r² ......equation 2.
Where;
h and k represents the coordinates of the centre.
r represents the radius of the circle.
Given the following data;
h = -1
k = 4
r = 5
Substituting into eqn 2, we have;
(x - {-1})² + (y - 4)² = 5²
Simplifying further, we have;
(x + 1)² + (y - 4)² = 25

y=mx-3
find the slope
y=-3/4x-3
Answer:
x = 20
m = 92
n = 68
p = 92
Step-by-step explanation:
x = 20
2 + 3x = 62
-2 -2
----------------
3x = 60
----- -----
3 2
x = 20
m = 92
20 + 68 = 88
180 - 88 = 92
n = 68
The vertical angle is 68 degrees
p = 92
Vertical angle is m, which is 92.

Answer: She's wrong.
Step-by-step explanation:
Numbers of hours used in solving homework last week = 15
Numbers of hours used in solving homework this week = 18
Percentage increase = (18 - 15) / 15 × 100
= 3/15 × 100
= 1/5 × 100
= 20%
Since Maxie said that she spent 120% more time doing homework this week, she's wrong. She only spent 20% more.
