Answer:
The center is (5, -2) and the radius is 9/2
Step-by-step explanation:
The equation of a circle can be written in the form
(x-h) ^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x − 5)^2 + ( y + 2 )^2 = 81/4
(x − 5)^2 + ( y - -2 )^2 = (9/2)^2
the answer is a because the 3 is a whole number and whole numbers are bigger than fractions and the thing next to the whole number is a fraction so its a
y = x + 4
Number of gallons still in tank = 4
+ Number of gallons added to tank = <u>x </u>
Total gallons in tank = x + 4
Then, Jane had twice as much money as her sister. How much money did their parents give each of them?
Let x = amt given to them
Solve this equation for x
7 + x = 2(2 + x) Jane had $7 and her sister had $2.
Their parents gave them each equal amount of money
Solution
Percent 27.5
Tall:48 inches
then
27.5/100×48
=13.2
