The graph of x = 2(y-4) and x = 5(y-4) are shown below answer my following question to receive brainlest!!!

Ivanshal [37]

Answer:

The graph $x = 2(y - 4)$ has a greater slope than the graph of $x = 5(y - 4)$ .

Step-by-step explanation:

$x = 2(y - 4)\\\frac{x}{-2y} = \frac{-2y}{-2y} - 4\\-2y \frac{x}{-x} = \frac{-4}{-x} \\\frac{-2y}{-2} = \frac{-1x}{-2} \frac{-4}{-2}\\y = \frac{1}{2}x + 8$ $x = 5(y - 4)\\\frac{x}{-5y} = \frac{5y}{-5y} - 20\\\frac{x}{-x} - 5y = \frac{-20}{-x}\\\frac{-5y}{-5} = \frac{-1x}{-5} \frac{-20}{-5}\\y = \frac{1}{5}x + 4$

Find the inverse of the functipn <br><br> f(x)=3x-7/2

vivado [14]

Answer:

2x+7/6

Step-by-step explanation:

an normal function would be mapping x to y, since this is the inverse we would map y to x

f(x) and y are the same so I will take f(x) as "y"

1)3x-7/2=y

3y-7/2=x

solve/isolate "y" in 3y-7/2=x to get the value of "y"

3y-7/2=x

add "7/2" to both sides

3y-7/2+7/2=x+7/2

3y=x+7/2

divide both sides by "3"

3y/3=x/3+7/2/3

simplify:

y=2x+7/6

hope this helps!

Which equation represents this statement? One-third of a number is 21.

Stella [2.4K]

Assuming c says 1/3x=21, that's the right answer. if you read too quickly you might rush into thinking x=7, but if course it is 63.
