8 0

Your question: Which equation has solution x = -3?

I'd like you to know: I couldn't find any answer that exactly answered X=-3, although there is an answer similar to. But if it was accidental, this would be the most <em>correct </em>answer.

Answer: A) 2x - 7 = -1

|Step-by-step explanation|

  • 2x - 7 = -1   =   x=3
  • 3x + 8 = 1   =   x=-7/3
  • x + 8 = 10   =   x=2
  • 11 (2x-6) = -6 = x=30/11

vladimir2022 [97]

For this case, we have to define perpendicular lines:

m1 * m2 = -1

We have then:

m1 = \frac {1} {5}\\m2 = -5

Then, according to the definition we have:

(\frac {1} {5}) (- 5) = \frac {-5} {5} = -1

We observe that the definition is fulfilled, therefore, the lines are perpendicular.

Answer:

b. they are perpendicular

erik [133]

Answer:

85 student tickets and 35 adult tickets were sold.

Step-by-step explanation:

Howdy!

We know that student tickets cost $12, adult ticket cost $20 and 120 tickets were sold.

So:

$12×A + $20×B = $1,720. Where A and B are the number of student tickets and adult tickets sold, respectively.

Given that 120 tickets were sold in total, we have that:

A + B = 120

So the system of equations to be solved is the following:

$12×A + $20×B = $1,720                    (1)

A + B = 120                                          (2)

Solving for 'A' in equation (2) we get:

A = 120 - B

Substituting this value into equation (1) we get:

$12×(120 - B) + $20×B = $1,720

Solving for 'B' we have:

$12×(120 - B) + $20×B = $1,720

$1,440 - $12×B + $20×B = $1,720

$1,440 + $8×B = $1,720

$8×B = $1,720 - $1,440

$8×B = $280

B = 35 tickets.

Given that B = 35, then A = 120 - 35 = 85 tickets.

So 85 student tickets and 35 adult tickets were sold.
