Answer:

520<400+15x

15x>120

15x+400>520

Explanation:

Pay of Dan's car wash attendant job =$400 per week

The amount he earns per hour walking dogs = $15

Let the number of hours spent walking dogs in a week = x

Therefore, total earning for walking dogs =$15x

Since he wants to earn more than $520, we have that:

15x+400>520\text{  (Option F)}

We can rewrite this as:

520

If we collect like terms, we have:

\begin{gathered} 520-400

So the inequalities are:

0. 520<400+15x

,

1. 15x>120

,

2. 15x+400>520

I believe you would have to multiply both 25 and 20 and what ever number you get dived by 100 if the numbers to high multiply aging or subtract the number (if it's wrong I'm really not good at my math I'm sorry)

Let g(x) = 2x2 - 11x. Find g(-1).<br> A) -13 Eliminate <br> B) -9 <br> C) 0 <br> D) 13
worty [1.4K]

Solution

g(x) = 2x^{2} - 11x

Plugging in x = -1 in g(x), we get

g(-1) = 2(-1)^{2} - 11(-1)

Now we have to simplify it.

g(-1) = 2*1 + 11

g(-1) = 2 + 11

g(-1) = 13

So the answer is D) 13.


Thank you. :)

Julli [10]
Answer:

The minimum number of bicycles that must be produced and sold to break even = 20

Explanation:

The profit generated by producing and selling n bicycles per week is given by the formula:

P(n)=-5n^2+400n-6000

To get the minimum number of bicycles that must be produced and sold to break even, let P(n) = 0 (Since break even means no profit is made)

\begin{gathered} 0=-5n^2+400n-6000 \\ 5n^2-400n+6000=0 \end{gathered}

Solve the resulting quadratic equation above

\begin{gathered} 5n^2-300n-100n+6000=0 \\ 5n(n-60)-100(n-60)=0 \\ (5n-100)(n-60)=0 \\ 5n-100=0 \\ 5n=100 \\ n=\frac{100}{5} \\ n=20 \\ n-60=0 \\ n=60 \end{gathered}

This means that, to break even, either 60 or 20 bicycles must be produced and sold

The minimum number of bicycles that must be produced and sold to break even = 20
