Answer:
y = -1/2x + 4
Step-by-step explanation:
You can see that the slope is -1/2 because of the rise over run.
It also crosses the y axis at 4,
so it is y = -1/2x + 4
Answer:
x = -1.14 or -13.14
Explanations:
The given equation is:

Find the half of 12, and add the square to both sides of the equation.
That is add 6² to both sides


Find the square root of both sides:

The cost of one drink is $2.50 and cost of one popcorn is $3.75
<u><em>Explanation</em></u>
Suppose, the cost of one drink is
dollar and cost of one popcorn is
dollar.
Given that, total cost for 2 drinks and 2 popcorns is $12.50 and total cost for 6 drinks and 5 popcorns is $33.75
So, the system of equations will be......

Multiplying equation (1) by -3 , we will get.....

Now, adding equation (2) and equation (3) , we will get ............

Plugging this
into equation (1) ......

So, the cost of one drink is $2.50 and cost of one popcorn is $3.75
