Question

* not multiple choice*

2/3n = 8

solving the system of equations
4x + 3y = 13
y= -x +4 * not sure how to do this


the slope intercept form of the function that contains the point (-3, 2) and has a slope of -2?
my answer: y= -2x + 6



-1 + 5(6-y)
my answer is -y + 29

Answer 1

Please number your question, how are we to know who is who and what you want done

1. assuming you want to solve 2/3n = 8
multiply each term by 3
2n = 24
n = 12

2.
sub the 2nd into the 1st
4x + 3y = 13
4x + 3(-x+4) = 13
4x - 3x + 12 = 13
x = 1
back into the 2nd, y = -1+4 = 3
x=1 , y=3

3. Why not sub the given point into the equation ?
Does it satisfy the equation? NOPE
so let
y = -2x + b
plug in your point (-3,2)
2 = -2(-3) + b
b = -4
so y = -2x - 4

4.
-1 + 5(6-y)
= -1 + 30 - 5y
= 29 - 5y
