Answer:
20
Step-by-step explanation:
We have two simultaneous equations.
(1) y = 2x + 50
(2) y = 4.5x
1. Subtract (1) from (2)
0 = 2.5x - 50
2. Add 50 to each side
2.5x = 50
3. Divide each side by 2.5
x = 20
Pilar must sell 20 items to break even.
You can find the x intercept of the equation by setting the value of y
to zero and solving the equation. Similarly you can solve the y
intercept by setting the value of x to zero and solving the equation.
Now while solving this rational function for intercepts if you face a
situation where the value in the denominator is zero it implies that
there is no intercept in that case as dividing something by zero is
indeterminate.
To find out how much time it would take for each group to tell their stories, we simply need to multiply the amount of people in each group by the amount of time it takes one member to tell a story.
We know that there are either 3 or 4 people in each group, and that it takes 3 minutes for each person to tell their stories, so we simply need to multiply
3 * 3 = 9
4 * 3 = 12
It will take either 9 or 12 minutes for each group to tell their scary stories.
Hope that helped! =)

Answer:
The simplified expression for the given expression will be:
c. 
Step-by-step explanation:
Given expression:
To simplify the expression.
Solution:
In order to simplify the expression, we will first remove the parenthesis by reversing the signs of the terms inside the parenthesis which lies after a negative sign out side the parenthesis.
<em>This is because negative multiplies to a negative to give a positive and negative multiplies to a positive to give a negative.</em>
So, we have:
⇒ 
Combining like terms
⇒ 
<em>The like terms can be evaluated as</em>
Thus, the simplified expression will be:
⇒
