Which of these graphs is the solution set for the equation y = -3x - 2?

Answers

A because y=-3x-2 has these transformations
The negative before the 3 means the slope is going down
The 3 means it goes 3 down every time it goes right one, the number before the x is the slope and slope is rise over run, 3 = 3/1 so it would normally mean it goes up 3 every time it goes right one but because the 3 is negative it means the line goes down
The negative two at the end moves the line down two, if it were plus two the line would go up two, the number in this spot is what determines the vertical translation

Put it all together and you get the line has goes down 3 every time it goes right one and crosses the y axis at -2

P.S. wouldn't mind getting brainliest

Answer:

Step-by-step explanation:

Frist you find negative 2 and you can see that 2 are going there so you need to find where negative 3 is when you add negatives they trun into a possitve so go up 3 times from negative 2.

Hello how are you :D

A camera company routinely ships cameras that have 4 defective cameras for every 800 cameras shipped. Bradley works at a photo shop that sells the cameras to consumers. If Bradley sells 200 cameras, how many can Bradley expect to be defective?

A.50 cameras

B.8 cameras

C.4 cameras

D.1 camera

Answers

D. 1 cuz think of it like this 8 divided by 4 = 2 and if that 2 is 200 hundred in every 200 hundred camera there’s 1 defective camera tell me if I’m wrong

The number of cameras Bradley expects to be defective if he sells 200 cameras is 1, so option D is correct.

What is ratio?

Comparing one quantity to another is what it is. For instance, the weight ratio is 1:3 if you weigh 30 kg and your father weighs 90 kg.

Given:

4 defective cameras for every 800 cameras shipped,

Bradley sells 200 cameras,

The ratio of the defective piece to cameras shipped = cameras shipped / defective cameras,

Ratio = 800 / 4 = 200

So for 200 cameras to be shipped, there is one defective piece.

Therefore, the number of cameras Bradley expects to be defective if he sells 200 cameras is 1.

Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3

Answers

Ccccccccccccccccccccc

The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.

What is the equation?

More than one variable may be present inside a linear equation.

An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

As per the given equation,

13 = -3 + z

Since, A + B = B + A

Thus, -3 + z can be written as z - 3

So, 13 = z - 3

Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".
