A direct variation is a proportional equation. Such as:

For every 3 cookies, linda gets 1 glass of milk. The equation for this is y=3x where y is the glasses and x is the cookies. this is a direct variation. It also has a linear line. Linear means straight. Rate of change and slope are the exact same thing. They are the value of 'm' in y=mx+b

StoreA<span>
numbers greater than or equal to zero
</span>
Store B<span>
numbers greater than or equal to zero
integer values only.

Store A sells by the gallon which is a continuous number so it can sell none or any numbers between 0 and infinity 

Store B sells per container so it can be 0 to infinity but only integer values, you cannot buy half of a container.

Answer:

x = 5 ; z = 70

Step-by-step explanation:

Vertical angles have the same degree measure

(13x + 45) = 110

13x + 45 = 110

      -45     -45

13x = 65

/13     /13

x = 5

Complementary angles add up to 180°

110 + z = 180

-110         -110

z = 70

Answer:

1/3

Step-by-step explanation:

I think this is 1/3 because it is a ratio of successful outcomes to total number of outcomes..

Ex. Rolling a 6 sided dice.. you roll a 5...  it would be 1/6.

Hope that makes sense.

1<br> Which expression can be simplified as this?
maks197457 [2]

Answer and Step-by-step explanation:

The answer would be the last answer choice.

(n^{-3} )^{6}

Exponents that are the being raised by another exponent get multiplied, so 6 times -3 is -18.

When a number/variable has a negative exponent, the number/variable will be put under 1, and the exponent will change to be positive.
