Carolyn was asked to solve the following system of equations. Her work is shown. Problem: Carolyn's Work:
3x - 2y = 7
3x - 2(x+2) = 7
y = x + 2
y = x + 2
3x - 2x + 4 = 7
y = 3 + 2
x + 4 = 7
y=5
X = 3
(3,5)
what error did carolyn make? identify her mistake.

what is the solution to the system of linear equations?

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if

(-y to the power of 2 - 4y- to the power of 2 -6 y +3)

Step by step explanation pls for 10 pts the length of a rectangular board is 3 feet less than twice its width. a second rectangular board is such that each of its dimensions is the reciprocal of the corresponding dimensions of the first rectangular board. if the perimeter of the second board is one-fifth the perimeter of the first, what is the perimeter of the first rectangular board?
