Your answer would be 4.

If we substitute in x = -8 and y = -4 into the expression, we get:

\frac{3(-8) - 4}{-4 - 3}

This then becomes:

\frac{-24 - 4}{-7} = \frac{-28}{-7} = 4.

I hope this helps!

Write a linear function f with f(0)=7 and f(3)=1.
choli [55]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

a = ( 0 , 7 ) & b = ( 3 , 1 )

First need to find the slope using the following equation :

slope =  \frac{y(b) - y(a)}{x(b) - x(a)}  \\

slope =  \frac{1 - 7}{3 - 0}  \\

slope =  \frac{ - 6}{3}  \\

slope =  - 2

_________________________________

We have following equation to find the point-slope form of the linear functions using the slope and one of the through points .

y - y(0) = m \times ( \: x - x(0) \: )

x(0) = x - coordinate \:  \: of  \:  \: through \:  \: point \\

y(0) = y - coordinate \:  \: of \:  \: through \:  \: point \\

m = slope

I choose point (( a )) to put in the equation.

y - 7 =  - 2 \times (x - 0)

y - 7 =  - 2x  + 0

y - 7 =  - 2x

Add sides 7

y - 7 + 7 =  - 2x + 7

y =  - 2x + 7

This the slope-intercept form .

Done...

F(x)=(x+1)(x-3)(x-4)
denis23 [38]

Answer:

x=-1, x=3, x=4

Step-by-step explanation:

1. Substitute 0 for f(x)

0=(x+1)(x-3)(x-4)

2. Set each set of parenthesis equal to 0

0=x+1, 0=x-3, 0=x-4

3. Solve for x

x=-1, x=3, x=4
