Answer:

(0,-1)

(1,-5)

(2,-9)

Step-by-step explanation:

y = −4x −1

Let x=0

y = 0-1 = -1 (0,-1)

Let x = 1

y = -4(1) -1 = -4-1 =-5 (1,-5)

Let x = 2

y = -4(2) -1 = -8-1 =-9 (2,-9)

Fred spent half his allowance on going to the movies he then washed the family car for six dollars he now has eleven dollars how

kotykmax [81]

Answer:

He gets $10 for his weekly allowance.

Step-by-step explanation:

Let x represent the amount that Fred gets for his allowance weekly.

Fred spent half his allowance on the movies. This means that the total amount that he spent on the movies is x/2. The amount that he is left with would be

x - x/2 = x/2

He washed the family car for six dollars. This means that the total amount that he is left with would be

x/2 + 6

if he now has eleven dollars, it means that

x/2 + 6 = 11

x/2 = 11 - 6 = 5

x = 2 × 5 = $10

The school that molly goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 6 sen

The cost of a senior citizen ticket is $15 and the cost of a student ticket is $12.

How did I get this?
We know that 6 citizen tickets and 7 student stickers sold for $174 the first day. And 10 citizen tickets and 14 student tickets sold for $318 the second day.

1. create two equations out of this: C= citizen cost per ticket and S = student cost per ticket.

6C + 7S = $174
10C + 14S = $318

2. Use process of elimination. Multiply the first equation by 2 because we want two variables to cancel out.

-12C - 14S = -$348
10C + 14S = $318
Combine like terms.

-2C = $30
Divide by -2 on both sides. The left side cancels out.

C = $30/-2
C = -$15 (In this case the negative doesn't matter)

C = $15 (cost of senior citizen ticket)

Plug the value of C into any of the two equations so we can get the value of S.

6($15) + 7S = $174
Distribute the 6 into the parenthesis.

$90 + 7S = $174
Subtract both sides by $90 and the left side will cancel out.

7S = $84
Divide both sides by 7.
S = $12

Student ticket: $12
Senior citizen ticket: $15
