To help pay for the next school event, Terry and Tony want to make a
Sloan [31]

a) Equation: Nx=475

b)

1st case: 119 tickets

2nd case: 106 tickets

3rd case: 95 tickets

Step-by-step explanation:

a)

Terry and Tony want to make a profit of

P = $475

in total from the ticket sale.

Here we call x the price per ticket.

Then we also call N the number of tickets sold: therefore, this total profit made by Terry and Tony from the ticket sale is the product between the tickets sold, N, and the price per ticket, x:

Nx

And since they want to do a profit of P = $475, we can therefore write

Nx=475

b)

The equation of part a) can be re-arranged as

N=\frac{475}{x}

where N is the number of tickets sold and x the price per ticket.

The 1st group of student want to charge  $4.00 per ticket, so

x = 4.00

And so the number of tickets that they should sell in this case is

N=\frac{475}{4.00}=118.8 \sim 119

The 2nd group of student want to charge  $4.50 per ticket, so

x = 4.50

And so the number of tickets that they should sell in this case is

N=\frac{475}{4.50}=105.6 \sim 106

Terry and Tony want to charge $5.00 per ticket, so

x = 5.00

And so the number of tickets that they should sell in this case is

N=\frac{475}{5.00}=95

The two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.

Hence, option C is the correct answer.

<h3>What are the solutions to the quadratic equation?</h3>

Given the equation; 9x² + 4 = 0

First, we subtract 4 from both sides.

9x² + 4 = 0

9x² = -4

x² = -4/9

Take the square roots of both sides

x = ±√(-4/9)

Rewrite -4/9 as (2i/3)²

x = ±√(2i/3)²

x = ±(2i/3)

Hence,

x = 2i/3, -2i/3

Therefore the two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.

Hence, option C is the correct answer.

2x-y=3; x=2 how do I solve this
Solnce55 [7]

2x-y=3

use the substitution method

2(2)-y= 3

4-y= 3

move 4 to the other side

sign changes from +4 to -4

4-4-y= 3-4

-y= 3-4

-y=-1

mutiply both sides by -1 to get +y

(-1)(-y)= (-1)(-1)

y= (-1)(-1)

Answer: y= 1
