Answer:

(-∞, -12), (2, ∞)

or

(-∞, -12) U (2, ∞)

Step-by-step explanation:

|3x + 15| > 21, |3x + 15| < -21

3x + 15 > 21,  3x + 15 < - 21

     -15    -15         -15     -15

------------------   -------------------

3x > 6               3x < - 36

÷3  ÷3               ÷3     ÷3

------------         ------------------

x > 2                  x < -12

(-∞, -12), (2, ∞)

or

(-∞, -12) U (2, ∞)

I hope this helps!

A system of equations is shown. y = 3x - 2;. y = x^2. What are the solutions to the system of equations?
Taya2010 [7]

Answer: the solutions to the system of equations are x = 2 and x = 1

Step-by-step explanation:

The system of equations given equation is

y = 3x - 2 - - - - - - - - - - 1

y = x^2 - - - - - - - - - - - - 2

Substituting 1 into equation 2, it becomes

x^2 = 3x - 2

x^2 - 3x + 2 = 0

We would apply the method of factorization in solving the equation. We will get two numbers such that when added, the result would be - 3x and when multiplied, the result would be 2x^2. The numbers are - 2x and - x. It becomes

x^2 - 2x - x + 2 = 0

x(x - 2) - 1(x - 2) = 0

(x - 2)(x - 1) = 0

x - 2 = 0 or x - 1 = 0

x = 2 or x = 1

murzikaleks [220]

Answer:the price of one senior citizen's ticket is $4

the price of one student ticket is $10

Step-by-step explanation:

Let x represent the price of one senior citizen's ticket

Let y represent the price of one student ticket.

On the first day of ticket sales the school sold 6 senior citizen tickets and 10 student tickets for a total of $124. This means that

6x + 10y = 124 - - - - - - - - - - 1

The school took in 98 on the second day by selling 12 senior citizen tickets and 5 student tickets. This means that

12x + 5y = 98 - - - - - - - - - - - 2

Multiplying equation 1 by 2 and equation 2 by 1, it becomes

12x + 20y = 248

12x + 5y = 98

Subtracting, it becomes

15y = 150

y = 150/15 = 10

Substituting y = 10 into equation 1, it becomes

6x + 10 × 10= 124

6x + 100 = 124

6x = 124 - 100 = 24

x = 24/6 = 4
