Answer:u need to x out some of them tabs
She can spend a little over 30 dollars each day, ($30.35)
> multiply the second equation by 2 and add it to the first equation.
2(-6x - 7y = -10)
-12x -14y = -20
8x + 14y = 4
-12x - 14y = -20
--------------------
- 4x + 0 = - 16
x = -16/-4
x = 4
> use x = 4 in either equation to find y
8(4) + 14y = 4
32 + 14y = 4
14y = 4 - 32
14y = -28
y = -28/14
y = -2
Answer:
(x - 2)² + (y - 1)² = 9
Step-by-step explanation:
The standard form equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
Filling in (h, k) = (2, 1) and r = 3, you have ...
(x -2)² +(y -1)² = 9
