An expression that uses variables to state a rule is a ______
nikdorinn [45]

<u>Formula</u>

<em>An expression that uses variables to state a rule is a </em><u><em>formula</em></u>

<h2>Explanation:</h2>

An expression that uses variables to state a rule is a formula. It's important to know that formulas uses the equals sign (=) and includes two or more variables. Formulas gives us information that we express symbolically. For example, the well known formula for the volume of a sphere is defined as:

V=\frac{4}{3} \pi r^3 \\ \\ \\ Where: \\ \\ V:Volume \ of \ the \ sphere \\ \\ r:Radius \ of \ the \ sphere

So in this formula we have a relationship between the volume of a sphere and its radius, so if we have information about the radius of it we can easily calculate the volume of it.

HELP ASAP IM IN A TIMED TEST 8TH GRADE MATH ​
sattari [20]

Answer:

C

Step-by-step explanation:

Convert them all to the form y = mx + c

1)

4x + 3y = 15

3y = -4x + 15

y = -4/3 x + 5

2)

3x - 4y = -8

-4y = -3x - 8

4y = 3x + 8

y = 3/4x + 2

3)

y + 1 = 4/3(x - 6)

y + 1 = 4/3x - 8

y = 4/3x - 9

4)

y = 3/4x - 5
