Answer:
(x+3)²+(y+5)² = 36
Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius of the circle
Given
Centre (-3, -5)
a = -3 and b = -5
radius r = 6units
Substitute
(x-a)²+(y-b)² = r²
(x-(-3))²+(y-(-5))² = 6²
(x+3)²+(y+5)² = 36
hence the required equation is (x+3)²+(y+5)² = 36
Answer: 24 cans
Step-by-step explanation:
Given
George has 9 fence
It requires 
cans to paint a fence
So, 9 fence required
9 fence requires 24 cans
Simplify 3.8x + 5.2x - 6.7 to 9x - 6.7
9x - 6.7 = 11.3
Add 6.7 to both sides
9x = 11.3 + 6.7
Simplify 11.3 + 6.7 to 18
9x = 18
Divide both sides by 9
x = 18/9
Simplify 18/9 to 2
<u>x = 2</u>
7x + 3y = -12
2x + 5y = 38
5y = -2x + 38
y = -2x/5 + 38/5
7x + 3•(-2x/5+38/5) = -12
29x/5 = -174/5
29x = -174
x = - 6
x=-6
y = -2x/5+38/5
y = -(2/5)(-6)+38/5 = 10
x=-6
y=10
