If the notebooks cost 3.59 and pens cost 1.49, with x representing the notebooks and y representing the number of pens and an amount of $13, the inequality would be written as 3.59x+1.49y\leq13

Let

x--------> the number of notebooks

y-------> the number of pens

we know that

3.59x+1.49y\leq13

using a graph tool

see the attached figure

The solution is the shaded area

therefore

<u>the answer is</u>

the inequality that represents the situation is equal to 3.59x+1.49y\leq 13

8 less than a number n is less than 11
iragen [17]

In mathematical form, it would be:

n-8 < 11

add 8 from both sides,

n-8+8 < 11+8

n < 19

So, n value must be less than 19

Hope this helps!

Help please thank you!
Dmitry_Shevchenko [17]

Answer:

g(f(x)) = x

Yes, the functions are inverses.

Step-by-step explanation:

Hi there!

We're given:

f(x) = 8x-7

g(x)=\displaystyle\frac{x+7}{8}

To solve for g(f(x)), plug f(x) into g(x) as x:

g(f(x))=\displaystyle\frac{(8x-7)+7}{8}\\\\g(f(x))=\displaystyle\frac{8x-7+7}{8}\\\\g(f(x))=\displaystyle\frac{8x}{8}\\\\g(f(x))=x

Because g(f(x)) = x, the two functions are inverses.

I hope this helps!
