Answer:
A) T is located on (-5, 2); radius = 9 units
Step-by-step explanation:
eqn of circle= (x-a)^2 + (y-b)^2 = r^2
where (a,b) is centre of circle.
(x+5)^2 = (x - (-5) )^2
(y-2)^2 = (y - (2) )^2
(-5,2)
r^2 =81
r = sqrt of 81
r = 9
Answer:

Answer:
x = -2
Step-by-step explanation:
Step 1: Substitute h(x) for -9
-9 = 4x - 1
Step 2: Solve for <em>x</em>
-8 = 4x
x = -2
Answer:
4x - 16
Step-by-step explanation:
5.5x + 1 - (1.5x + 17)
5.5x + 1 -1.5x -17
Combine like terms
4x + 1 -17
4x -16
