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 center is (5, -2) and the radius is 9/2
Answer: D
Because there is a dashed line, that means there has to be an inequality statement, C is the only one with one and the statement is false.
Answer:
Hi, the answer is 38,542
Step-by-step explanation:
B the new one update is not a good app but it needs a new phone version for a new
a(2a-3(1-a))+5(a-a^2)
distribute the inner most parenthesis
a( 2a -3+3a))+5(a-a^2)
combine like terms
a(5a-3) +5(a-a^2)
distribute both sets of parenthesis
5a^2 -3a +5a-5a^2
combine like terms
5a^2-5a^2 -3a+5a
2a
