Which linear equation represents a proportion relationship?

A) y = x + 2

B) y = 3x + 0.2

C) y = -0.3x

D) y = 3x + 4

Answers

Answer 1

Answer:

C

Step-by-step explanation:

C because in proportions your multiply and divide, not add or subtract. Example: 2/3=4/5 is 2x5 and 3x4 which equals to 10=12 therefore 2/3=4/5 is not proportional. If they equaled they would be proportional.

steps to the answer of 1/3(n+6)=−10?

Answers

Answer: n=−36

Step-by-step explanation: When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 n+36

 ———— • 3 = 0 • 3

  3  

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  n+36  = 0

 Solve  :    n+36 = 0  

Subtract  36  from both sides of the equation :  

                     n = -36

1. Distribute to clear out parentheses
2. Subtract 2 from both sides
3. Multiply by 3 on both sides

A number system is defined as a system of writing to express numbers.

A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

Given that A diver is 20 feet below the surface of the water.

We have to find on the number line best represents this location

The point is -20 because it is given that the diver is 20 feet below.

As it is given below we have to consider the negative sign.
