Answer:

$y=x$

Step-by-step explanation:

We will use slope-intercept form:

$y=mx+b$

Where $m=$ slope and $b =$ y-intercept

To find the slope we use the slope formula:

$\frac{y_2-y_1}{x_2-x_1}$

We plug in the coordinates getting:

$\frac{6-2}{6-2} =\frac{4}{4} = 1$

So we have a slope of 1:

$y=(1)x+b$

If we look at the answer choice we see that only one of them has a slope of 1 so the equation is:

$y =x$

Find f(x) and g(x) so that the function can be described as y = f(g(x)). (5 points) y = eight divided by square root of quantity

zubka84 [21]

Answer:

f(x) = 8/√x
g(x) = 2x+4

Step-by-step explanation:

For this sort of problem, there can be an infinite number of answers.

It can be convenient to choose one of the simpler answers by looking at the operations that are performed on the variable. Here, you have ...

2 multiplies it
4 is added to the product
the square root is taken
8 is divided by that root

You can work from the bottom up and define the outer function (f(x)) to be any of these operations. In our answer above, we have elected to include the "square root" and the "8 divided by that root" in our definition of f.

Then our function g takes care of the other operations.

Answer:

Step-by-step explanation:

Given that:

Batting average = 0.25 after 160 times at bat;

Batting Average = Number of hits / number of times at bat

0.25 = number of hits / 160

Number of hits = 0.25 * 160 = 40

He want batting average to improve to 0.333 ; if he makes hit the next x times at bat ; number of hits is needed to improve batting average

Hence,

New average = number of hits / number of times at bat

0.333 = (number of hits + x) / (160 + x)

0.333 = (40 + x) / (160 + x)
