Answer:

x = 10

y = 11

Step-by-step explanation:

Solve for x:

2x + 3y = 53

3x(3) - y(3) = 19(3)

2x + 3y = 53

9x - 3y = 57

Add:

2x = 53

9x = 57

11x = 110

Solve algebraically:

x = 110 ÷ 11

x = 10

Now solve for y:

2(10) + 3y = 53

20 + 3y = 53

3y = 53 - 20

3y = 33

y = 33 ÷ 3

y = 11

Verify for the second equation:

3x - y = 19

3(10) - (11) = 19

30 - 11 = 19

30 = 19 + 11

30 = 30 (Correct)

Cheers!

Write the equation of the given circle. center (1, -5) radius of 10

Ksenya-84 [330]

The circle equation is in the format (x – h)2 + (y – k)2= r2, with the center being at the point (h, k) and the radius being "r".

Therefore (x – 1)2 + (y +5)2= 102
x2 + y2 + 1 - 2x + 25 + 10y = 100
x2 + y2 - 2x + 10y = 74
