Answer:

-7 goes in the box

Step-by-step explanation:

x^ -3 = x^4 * x^n

We know that a^b * a^c = a^ (b+c)

x^-3 = x^(4+n)

When the bases are the same the exponents are the same

-3 = 4+n

Subtract 4 from each side

-3 -4 = 4+n-4

-7 = n

A group of friends wants to go to the amusement park. They have no more than $165

Oksi-84 [34.3K]

Answer:

17.75x + 5.25 $\leq$ 165

x $\leq$ 9

Step-by-step explanation:

The total cost can be represented by 17.75x + 5.25, where x is the number of people.

They can only spend a maximum of $165, so a less than or equal sign has to be used.

The inequality will be 17.75x + 5.25 $\leq$ 165

Now, solve for x:

17.75x + 5.25 $\leq$ 165

17.75x $\leq$ 159.75

x $\leq$ 9

So, x $\leq$ 9 is the answer, meaning 9 people or less can go to the amusement park.

Explain the steps needed to determine the value of the expression shown below be sure to provide the correct value of the expres

inn [45]

Answer:

-3/2

Step-by-step explanation:

In the picture attached, the complete question is shown.

The expression is:

$\frac{ \frac{1}{2} }{ \frac{-2}{5}} + \frac{-1}{4}$

You can rewrite the first term, expressing the division as a multiplication, that is, inverting the fraction in the denominator, as follows:

$\frac{1}{2} \times \frac{-5}{2}+ \frac{-1}{4}$

$\frac{-5}{4} + \frac{-1}{4}$

The addition of a negative fraction is simply the subtraction by that fraction:

$\frac{-5}{4} - \frac{1}{4}$

$\frac{-5 - 1}{4}$

$\frac{-6}{4}$

Which can be simplified dividing by two both numerator and denominator:

$\frac{-3}{2}$

How many solutions does the system of equations have?

Anestetic [448]

Answer:

no solution

Step-by-step explanation:

a solution would mean a point where the two lines cross. theres no such thing for parallel lines.

but if the lines are the same, they are parallel and cross everywhere, that would give infinite solutions.

if they would cross once, it would mean one solution
