Korvikt [17]

Answer:

$g(15)=93.8\%$

see the explanation

Step-by-step explanation:

Let

x ----> the number of years since 2008,

g(x) ----> the percent of people 25 years and older who have completed at least high school

we know that

$g(x)=0.008x^2+0.42x+87.5$

so

For x=15 years since 2008

substitute

$g(15)=0.008(15)^2+0.42(15)+87.5=93.8\%$

That means

In the year 2023 (2008+15) the percent of people 25 and older completing at least high school will be 93.8%

X-4x-32=0, explain the steps of answering it

zzz [600]

First step: combine the x terms, x - 4x = -3x.

Second step: Add 32 to both sides, which will cancel out the -32.

Now you have -3x = 32.

To solve for x, divide 32 by -3. The answer is -10.667.
