Answer:

D is true

Step-by-step explanation:

Lets look at all options.

Option A is not true because 0.004 is greater than 0.0038 by 0.0002 and 0.004 is not less than 0.0038

Option B is not true because 0.075 is not equal to 0.00749 in fact it is 0.001 greater than 0.0749.

Option C is not true because 0.5001 is greater than 0.4731 by 0.001 and not less than 0.4731

Option D is true because 0.7910 is equal to 0.791 and the only difference is the significant figures. 0.7910 has four significant figures and 0.791 has three significant figures.

Which ordered pair would form a proportional relationship with the point graphed below?
kvasek [131]

Answer:

(x,y) = (-30,10)

Step-by-step explanation:

Given

(x,y) = (60,-20)

Required:

Determine a pair with a proportional relationship

A proportional relationship is:

k = \frac{y}{x}

Where k is the constant of proportionality.

(x,y) = (60,-20)

So, we have:

k = \frac{-20}{60}

k = -\frac{1}{3}

This means that for a pair to have a proportional relation, k must be -1/3.

This is true for (c).

Where:

(x,y) = (-30,10)

So, we have:

k = \frac{10}{-30}

k = -\frac{1}{3}

What is 2y+5x-z=4y+6x and im solving for y
kap26 [50]
Simplifying
2y + 5x + -1z = 4y + 6x

Reorder the terms:
5x + 2y + -1z = 4y + 6x

Reorder the terms:
5x + 2y + -1z = 6x + 4y

Solving
5x + 2y + -1z = 6x + 4y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.
5x + 2y + -6x + -1z = 6x + -6x + 4y

Reorder the terms:
5x + -6x + 2y + -1z = 6x + -6x + 4y

Combine like terms: 5x + -6x = -1x
-1x + 2y + -1z = 6x + -6x + 4y

Combine like terms: 6x + -6x = 0
-1x + 2y + -1z = 0 + 4y
-1x + 2y + -1z = 4y

Add '-2y' to each side of the equation.
-1x + 2y + -2y + -1z = 4y + -2y

Combine like terms: 2y + -2y = 0
-1x + 0 + -1z = 4y + -2y
-1x + -1z = 4y + -2y

Combine like terms: 4y + -2y = 2y
-1x + -1z = 2y

Add 'z' to each side of the equation.
-1x + -1z + z = 2y + z

Combine like terms: -1z + z = 0
-1x + 0 = 2y + z
-1x = 2y + z

Divide each side by '-1'.
x = -2y + -1z

Simplifying
x = -2y + -1z
