Let f(x)=-4x-2 and g(x)=5x-6. Find F×G And state it's domain

klemol [59]

ANSWER

A) -20x²+14x+12; all real numbers

EXPLANATION

The give functions are;

$f(x) = - 4x - 2$

and

$g(x) = 5x - 6$

$(f \times g)(x) = f(x) \times g(x)$

$(f \times g)(x) = ( - 4x - 2)(5x - 6)$

$(f \times g)(x) = - 20 {x}^{2} + 24x - 10x + 12$

$(f \times g)(x) = - 20 {x}^{2} + 14x + 12$

This is a polynomial, hence the domain is all real numbers.

Find the slope of the line whose equation is 6y-12x=11

marta [7]

Answer:

Step-by-step explanation:

Convert it to slope/intercept form ( y = mx + c where m = the slope).

6y - 12x = 11

6y = 12x + 11

Divide through by 6:

y = 2x + 11/6

The slope is 2.
