Answer:
Equation of a circle:
radius = the sq. rt of (x - h)^2 + (y - k)^2
Plug in the values for the center of a circle and the radius:
15 = the sq. rt of (x + 9)^2 + (y + 4)^2
(x + 9)^2 + (y + 4)^2 = 225
The answer is A or the first one.
42 cm because if you divide 210 and 1260 it will make 6 so u just multiply it by 7 and u get 42
Answer ; -1/2
when expanded
5-8a-2+3a=13
5a=3-13
a=-5/10
a= -1/2

Answer:
Infinite solutions.
Step-by-step explanation:
Just plug your equation into desmos graphing calculator and it will graph it for you. If it is infinite the two lines will lay on top of one another. If there is only one solution it will be where the two lines intersect. If there are no solutions the two lines will be parallel.
