The answer is C. This is because the red paint must be proportional to the yellow paint, and the proportion given to us is 6/8 (or 6:8 as a ratio). We notice that when simplified, 6/8=3/4, meaning that for every 3 parts of red, there are 4 parts of yellow. By multiplying 3/4 by a certain number of parts for yellow, we'll get the proportionate parts for red.

For example, if you wanted to find out the proportionate part of red for 16 parts of yellow, you would do 3/4*16, which is 12, so that would be 12 parts of red.

Which number number is equal to |-12|-|-3| ?

9 because the symbols around -12 and -3 so they would just become positive number 12 and 3. Subtract them and you get 9 :)

Graph a line that is parallel to the given line. Determine the slope ofthe given line and the one you graphed in simplest form.

Daniel [21]

original slope = -4/3

parallel slope = -4/3

Explanation:

For a line to be parallel to anpother line, the slope of both lines must be equal.

We need to find the slope of the given line by picking any two points on the line.

Using points (-6, 5) and (0, -3)

slope formula:

$m\text{ = }\frac{y_2-y_1}{x_2-x_1}$ $\begin{gathered} x_1=-6,y_1=5,x_2=0,y_2\text{ = -}3 \\ \text{slope = m= }\frac{-3-5}{0-(-6)}=\frac{-8}{0+6} \\ m\text{ = -8/6} \\ m\text{ = -4/3} \end{gathered}$

The equation of the given line: y = mx + b

b = y-intercept = -3

y = -4/3x - 3

The equation line parallel to the one above could be:

y = -4/3 x + 7

This because the slope are the same

original slope = -4/3

parallel slope = -4/3
