A. To answer this question, we must consider two inequalities. The first inequality we will construct is regarding the number of tickets sold with respect to capacity. The theater cannot exceed the allotted 200 seats, so this would indicate we would use a less than or equal to inequality. The inequality we would construct to illustrate this using adult and child tickets is x + y <= 200.
The second inequality we will construct is based upon the ticket prices set and the theater’s goal. The problem indicates the theater wants to sell “at least $1,500 worth of tickets...” To create the inequality here, we will create it as follows: 12.5x + 6.25y >= 1,500.
To find the intersection point, we must isolate y. In order to do this, move x to the other side of both inequalities. Inequality 2 can be simplified to y >= -12.5x / 6.25 + 1,500 / 6.25. Graph and identify the solution from there.

Write an equation and solve: Twice a number, increased by 3 is 7.
Artist 52 [7]
'number' will be x
2x+3=7
subtract 3 on both sides:
2x=4
divide by 2 on both sides:
x=2
So the answer to the problem is A

SOMEONE PLEASE HELP ME WITH THIS QUESTION !!!

Answer:

$700

Step-by-step explanation:

Given that:

Cost of desktop PC 10 years ago = $6000

Cost of desktop PC 2 years ago = $300

Linear model applies.

To find the rate of decrease per year, we need to find the slope.

One quantity is cost of PC here and second quantity here is number of years.

\text{Rate of decrease per year = }\dfrac{\text{Change in Price}}{\text{Change in Number of years}}

\Rightarrow \dfrac{6000-300}{10-2}\\\Rightarrow \dfrac{5700}{8}\approx \bold{\$700}

So, the answer is:

There is a decrease of <em>$700 </em>per year.

OR

Rate of decrease per year is <em>$700</em>.
