Oh ok fine I just want to make sure you know that I don’t want you to the route cover 4/5
The equation of a circle with center at (h,k) is
(x-h)^2+(y-k)^2=radius^2
given
(x-(-1))^2+(y-3)^2=9
center is (-1,3)
first option
If the boy grows another 5 inches, he will be 1/2 as tall as his sister. HIs sister is 68 inch tall
Let sister = g, and boy = b
2b + 5 = g
g = 68
Plug in 68 for g
2b + 5 = 68
Isolate the b. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
first, subtract 5 from both sdies
2b + 5 (-5) = 68 (-5)
2b = 68 - 5
2b = 63
Isolate the b. Divide 2 from both sides
2b/2 = 63/2
b = 63/2
b = 31.5
The boy is 31.5 inches tall
hope this helps
