I need help with this one math question please!

Answer:

see explanation

Step-by-step explanation:

Assuming the fractions are being multiplied

Factorise the denominators of both fractions

x² - 3x - 10 = (x - 5)(x + 2)

x² + x - 12 = (x + 4)(x - 3)

The product can now be expressed as

\frac{x-5}{(x-5)(x+2)} × \frac{x+2}{(x+4)(x-3)}

Cancel (x - 5) and (x + 2) on the numerators/ denominators, leaving

\frac{1}{(x+4)(x-3)} = \frac{1}{x^2+x-12}

Write an equation of the line with the given slope, m and y intercept (0,b) m=-6, b =-1/2 plss
Arlecino [84]

Recall that an equation in slope-intercept form is as follows:

y=mx+b,

where m is the slope of the line, and (0,b) is the y-intercept.

Substituting m=-6, and b=-1/2 we get:

y=-6x+(-\frac{1}{2})\text{.}

Simplifying the above result we get:

y=-6x-\frac{1}{2}\text{.}

Answer:

y=-6x-\frac{1}{2}\text{.}
