Answer:

-12m-6n

Step-by-step explanation:

Let's break this down systematically

Start:

8m + 2n - 4(5m - 2n)

Use the distributive property

8m + 2n - <u>4(5m - 2n)</u>

8m + 2n - 20m - 8n

Match like terms <em>m </em>and <em>n</em>

8m - 20m = -12m

2n - 8n = -6n

<u>-12m-6n</u>

Answer: No solution

Step-by-step explanation:

First, rearrange the second function:

3x - y = 2 \\-y=-3x+2\\y=3x-2

Because the two equations share the same slope of 3, they're parallel lines, that means they don't ever intercept. Therefore, there are no solutions.

How can you remember the difference between supplementary and complementary angles
Klio2033 [76]
I always remembered it as the 's' (for supplementary) is farther than 'c' (for complementary) in the alphabet just like 180 degrees is farther than 90 degrees

so supplementary is 180 degrees
complementary is 90 degrees
