WILL MARK BRAINLIEST! Solve for X and Y

1a) x = -41

1b) x = -1

1c) x = 29/3, or x = 9.66 in decimal form

1d) x = -4

2a) y = -3

2b) y = -60

2c) y = -83

2d) y = -50

Step-by-step explanation:

1a) y = x  + 11

-30 = x  + 11

-11           -11

-41 = x

1b) y = -2x - 32

-30 = -2x - 32

+32         +32

2 = -2x

/-2   /-2

-1 = x

1c) y = -3x - 1

-30 = -3x - 1

+1             +1

-29 = -3x

/-3     /-3

29/3 = x

9.66 = x

1d) y = 5x - 10

-30 = 5x - 10

+10         +10

-20 = 5x

/5      /5

-4 = x

2a) y = x + 3

y = -6 + 3

y = -3

2b) y = -2x - 72

y = -2(-6) - 72

y = 12 - 72

y = -60

2c) y = 3x - 65

y = 3(-6) - 65

y = -18 - 65

y = -83

2d) y = 4x - 26

y = 4(-6) - 26

y = -24 - 26

y = -50

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
