Which of the following lines has a slope of -1/3 and a y-intercept of 6? x - 3y = 6 x + 3y = 18 3y - x = 18

erastovalidia [21]

The second choice is correct, but I believe that either its +1/3 ( in the question) or -3y as that will give you the answer of: y=1/3x+6

Does anyone know how to do this?? steps are helpful but not necessary

aniked [119]

Answer:

C. $\frac{2(x+16)}{x+4}$

Step-by-step explanation:

We want fg of x, so first we have to multiply f(x) times g(x).

$\frac{x+16}{x} * \frac{2x}{x+4}$

$\frac{(x+16)2x}{x(x+4)}$

$\frac{2x^{2}+32x}{x^{2}+4x}$

We can cancel out an x from every term.

$\frac{2x+32}{x+4}$

Let's rewind a little to get this into one of the answer choices.

$\frac{2(x+16)}{x+4}$ is our answer.

HELP PLZ <br> i need help with this math side i just need b,c,d a =4x+2y=16

tino4ka555 [31]

Answer:

Please check the explanatio.

Step-by-step explanation:

Solving Part b)

We know that the slope-intercept form of the equation line is

$y=mx+b$

where m is the slope and b is the y-intercept

Given the equation

$4x+2y=16$

Re-writing the equation in the slope-intercept form

$4x+2y=16$

$y=-2x+8$

Here, m=-2 and b=8

Thus, the equation in the slope-intercept form will be:

$y=-2x+8$

Solving Part c)

As you sold two pounds of cheddar cheese.

i.e. y=2

substituting y=2 in the slope-intercept form of the line equation

$y=-2x+8$

$2=-2x+8$

Subtract 8 from both sides

$-2x+8-8=2-8$

$-2x=-6$

Divide both sides by -2

$\frac{-2x}{-2}=\frac{-6}{-2}$

$x=3$

You sold 3 pounds of swiss cheese.

Solving Part d)

$y=-2x+8$

putting x=2.5 in the equation

$y=-2x+8$

$2=-2\left(2.5\right)+8$

$2=3$

The sides are not equal

<em>FALSE</em>

Thus, x=2.5 does not make any sense in the context of the problem.
