X=18+9/2y help <br> Me please
Nana76 [90]

Answer:

x = 18 + 9y/2

x-18 = 9y/2

(x-18)x2=9y

2(x-18)=9y

2(x-18) / 9 = y

y= 2(x-18)/9

Step-by-step explanation:

<em>Simplify 9/2y to 9y/2</em>

<em>Then Subtract 18 from both sides</em>

<em>Now Multiply both sides by 2</em>

<em>Then Regroup the terms</em>

<em>now divide both sides by 9</em>

<em>Then you will Switch sides</em>

Data from the Centers for Medicare and Medicaid Services indicates that the annual per capita out-of-pocket expenses for health
Talja [164]

Answer:

During the year 2021.

Step-by-step explanation:

As we have a function that defines the annual per capita out-of-pocket expenses for health care, we can work with it.

Knowing that, <u>we clear x</u> (<em>this is the number of years past the year 2000, so it will contain our desired information</em>).

y=39.6x+543\Leftrightarrow x=\frac{y-543}{39.6}

Now, as we want to know when are the per capita out-of-pocket expenses for health care predicted to be $1400, and <em>this total is our variable y</em>, then

x=\frac{1400-543}{39.6}\approx 21.6

Finally, we know that <u>x is the number of years past the year 2000</u>, so the answer is that during the year 2021, <em>the per capita out-of-pocket expenses for health care are predicted to be $1400</em>.
