Your answer is choice D:

By equation, the form of a proportional relationship is y = kx
By graph, a proportional relationship can be noticed by observing the graph of the line passing through the origin.
By Table, a proportional relationship will satisfy the following: $k = \frac{y}{x}$ where k is the constant of proportionality.

In choice D, divide each y coordinate in the table by its corresponding x coordinate and you will see that the answer is 1.5 for each.. This is your k, or constant of proportionality.

Nick had 3 1/4 bottles of water for his wrestling practice when he finished he had 124 bottles of water left he said he used to

Ostrovityanka [42]

Nick had 3 1/4 bottles before, and he had 1 2/4 bottles left, so that means
3 1/4 - 1 2/4 = 1.75
1.75= 1 3/4.
So, I do not agree with nick.

Hope this helps!!! :)

What is the solution to this equation?

Fantom [35]

Answer:

x=-17

Step-by-step explanation:

Original Equation;

x+12=-5

The 12 will cross the equal sign so it will become -12. So it's going to be;

x=-5-12

There are two negative number so you add them and when you add them it would still be negative. And you would have to add them because when there are two negative numbers without any other sign you will have to add so it's going to be;

x=-17

This is the final answer!!!

+(-6) + (-8)= -4 What’s the missing number???

Darya [45]

Answer:

Step by step explanation:

In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.

Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."

x + (-6) + (-8) = -4

x + (-6 + -8) = -4

x + (-14) = -4

x + (-14 + 14) = -4 + 14

x = 10
