I REALLY NEED HELP!! PLEASE HELP ME!

x^2 - 3x - 40 = 114.

Step-by-step explanation:

They offered x styles and x colours last year.

After increasing by 5 and decreasing by 8 they offered

(x + 5)(x - 8) and this equals 114.

So (x + 5)(x - 8) = 114

x^2 - 3x - 40 = 114.

This works out to 14 styles.

We can check the result  as follows

Last year the number of combinations of color and style was 14*14 = 196.

This year it is 14+ 5 = 19 styles and 14 - 8 = 6 colors.

This comes to 19 * 6 = 114.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
