Explain how to decide if a proportion is true or false. Please include an example : A proportion is an equation comparing two ratios. If the ratios are identical, the proportion is true. If not, the proportion is false.

explain how i got the answer and include example to go with answer above break down how you would got the example

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

1,589.63 in.^3

step-by-step explanation:

i hope this you : d

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
