Answer:

-2

Step-by-step explanation:

slope equation: (y2-y1)/(x2-x1)

lets use (-4, 9) as x1 and y1 and (3, -5) as x2 and y2

when plugged into the equation we get (9+5)/(-4-3) which ultimately equals -2.

Given h(x)=(3x-4), f(x)=(-7x+2), and g(x)=(9x+1), which of the following is equivalent to 2x+3?

Triss [41]

Answer:

f+g is right answer.

Step-by-step explanation:

given

$h(x)=(3x-4), \\f(x)=(-7x+2),\\ and g(x)=(9x+1)$ ,

2x+3 is given and we have to find the combinations of h,f and g.

By trial and error we check h+f

= -4x-2

h-f = 10x-6

So these two are not correct

Try with h+g = 12x-3 and h-g = -6x-5

Hence these are also not right

Try with f+g

(f+g)(x) = f(x)+g(x) = -7x+2+9x+1 =2x+3

Hence f+g is right.
