If ab= 7x-6 and bc= 12-2x. Then what does ac equal?

Ab = (7x-6) →   b = (7x-6)/a   (1)

bc = (12-2x) → b = (12-2x)/c   (2)

Since (1) = (2) → (7x-6)/a = (12-2x)/c OR  a/c = (7x-6)/(12-2x)  (3)

Multiply  both numerators of (3) by the SQUARE of their  respective denominators;

(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:

ac = (7x-6)(12x-2x)  or ac = -14x² + 96x - 72

Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of y plus StartFraction one-hal
inn [45]

Answer:

y-2=3(x-3)

Step-by-step explanation:

We want to write the equation of a line in point-slope form.

This is given by:

y-y_1=m(x-x_1)

We have that line passes through (3,2).

Assuming the line has a slope of m=3, then the equation in point slope form is:

y-2=3(x-3).
