Hope this helps!!
Answer: 28
Step-by-step explanation: Look at the numerators(the top numbers). Do 8 divided by 2. That equals 4. By doing this, we know that 2 x 4 = 8. Multiply 7 by 4 to get 28. The reason why you multiply 7 by 4 is because if you multiply 4 on top, you have to multiply by 4 on the bottom.

Answers
Answer:
The power for the volume of the cube is '3'.
Exponent form of the volume is
Volume of the cube is inch³.
Step-by-step explanation:
We are given,
A cube with side equal to inches.
As we know,
Volume of a cube =
Thus, we get,
Volume of the given cube is,
Volume =
i.e. Volume = inch³

The power for the volume of the cube is '3'.
Exponent form of the volume is
Volume of the cube is inch³.
Which of these graphs is the solution set for the equation y = -3x - 2?
Answers
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:
D
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.

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
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
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".
