Answer:
Option a :
Step-by-step explanation:
Given :
The drama club sold 100 tickets to a show, it had $300 in profit.
The next show, it had sold a total of 200 tickets and had a total of $700 profit.
To Find : Equation models the total profit, y, based on the number of tickets sold, x
Solution :
For 100 tickets he had $300 in profit .
⇒ (
)=(100,300)
For 200 tickets he had $700 in profit .
⇒ (
)=(200,700)
We will use point slope form i.e.
--(A)
Now, to calculate m we will use slope formula :



Now, putting values in (A)
Thus Option a is correct i.e.
Answer:
-4 -23i
Step-by-step explanation:
(4-16i) - (8+7i)
Distribute the minus sign
4-16i -8-7i
Combine like terms
4-8 -16i -7i
-4 -23i
I could use the points so if you want to mark this as helpful that would be cool :)
Answer:
After 6 months, Casey would pay $360 to join either gym.
Step-by-step explanation:
At the first gym, the cost is $35 per month in addition to a $150 joining fee. So, the equation based on 'x' number of months and a total cost of 'c' is:
c = 35x + 150
At the second gym, the cost is just $60 per month. So, the equation based on 'x' number of months and a total cost of 'c' is:
c = 60x
Since you want to find the number of months 'x' it would take until Casey would pay the same amount to be a member of either gym, you can take the two equations and set them equal to each other:
35x + 150 = 60x
Subtract 35x from both sides: 35x - 35x + 150 = 60x - 35x or 150 = 25x
Divide both sides by 25: 150/25 = 25x/25 or x = 6
So, after 6 months, the cost would be same. The find the cost, replace 'x' with 6 in one of the equations: c = 60(6) = $360.
