24x + 7=79
subtract 7 from both sides
24x + 7 - 7= 79 - 7
24x= 72
divide both sides by 24
x= 3
CHECK:
24x + 7= 79
24(3) + 7= 79
72 + 7= 79
79= 79
ANSWER: x= 3
Hope this helps! :)
2 over 45 just so that you know
Answer:
(3, 4)
Step-by-step explanation:
You can do this by completing the square
x^2 - 14x + y^2 + 8 = 16
(x - 7)^2 - 49 + (y + 4)^2 - 16 = 16
(x - 7)^2 + (y + 4)^2 = 16 + 16 + 49 = 81
so the center is at (7 , -4) and radius = sqrt81 = 9
