Answer:
(3,4) is the solution of both equations.
Step-by-step explanation:
The given equations are :
3x – 2y = 1 ....(1)
4y = 7+3x
4y-3x = 7 .....(2)
Put x = 3 and y = 4 in equation (1).
3(3) – 2(4) = 9-8
= 1
So, (3,4) is the solution of the equation (1).
Again put x = 3 and y = 4 in equation (2).
4(4)-3(3) = 16-9
= 7
Hence, (3,4) is the solution of both equations.

Answer:
i believe 5 is 216.
Step-by-step explanation:
because the top, (3x2) = 6, and all the sides are equal on the bottom .
so 6 cubed
Answer:
The equation of a circle having the center (a, b) and radius r could be formulated by:
(x - a)^2 + (y - b)^2 = r^2
A circle, which has equation form: (x + 3) ^ 2 + y ^ 2 = 81, can be turned into:
(x - -3)^2 + (y - 0)^2 = 9^2
=> center (-3, 0)
=> radius = 9
=> Option 1 is correct
=> Option 4 is correct
=> Option 7 is correct
Hope this helps!
