Answer:

(6x+3) (4x-5) = 24x^2 -30x +12x -15 = 24x^2 -18x -15

I get the same answer. I guess we're both wrong?

Or do they want it reduced to:

8x^2 -6x -5

Using the equation y = 3x – 5, what would the output be for an input of -4?

Answer:

your question is really not clear but if you were to put the -4 in the Y then the answer would be X=1/3, if you plug in -4 for X and find Y then Y = -17

Step-by-step explanation:

plug in -4 in Y

-4=3x-5 add 5 on both sides,

1 = 3x divide 3 on both sides

1/3= x

plug in -4 in X

y = 3(-4)-5 multiply 3 and -4 = -12

y = -12-5 subtract the -12 and -5 = -17

y = -17
