Answer:
x²-6x+y²-4y=-4
Step-by-step explanation:
We know the circle equation stands like this:
(x-a)² + (y-b)² = R²
and (a,b) is center
and R stands for Radius
so in this case:
center = (3,2)
R = 3
So
(x-3)² + (y-2)² = 9
x²-6x+9 + y²-4y+4=9
x²-6x+y²-4y=-4
Answer:
0.93 pounds
Step-by-step explanation:
16.74÷18 = 0.93
8f + 3r > 8r + 3f
8f + 135> 360 + 3f
125 : 5 = 25

<h3><u>Dave is 96 years old.</u></h3><h3><u>Jim is 32 years old.</u></h3><h3><u>Bill is 64 years old.</u></h3>
d = 3j
j = 1/2b
64 = (d + j + b)/3
d = 3(1/2b)
d = 1.5b
64 = (1.5b + 1/2b + b)/3
Combine like terms.
64 = (3b)/3
Multiply both sides by 3.
192 = 3b
Divide both sides by 3.
64 = b
Because we have the value for b we can plug it into the other equations to solve for the other ages.
j = 1/2b
j = 1/2(64)
j = 32
d = 3j
d = 3(32)
d = 96
Answer:
11 inches
Step-by-step explanation:
7^2+8^2=c^2
49+64=c^2
113=c^2
square root both side
c=10.63014581
round up and get c=11
hope this helped :)
