Answer:
Step-by-step explanation:
Solve the inequality 5x − 4y > 20 for y, as follows: Subtract 5x from both sides, obtaining:
-4y > 20 - 5x;
Then divide all terms by -4:
y < -5 +(5/4)x, where the direction of the inequality sign has been reversed because of division by a negative quantity.
Temporarily replace the < symbol with = obtaining y = -5 +(5/4)x. Now choose at least three x values and find the corresponding y values. For example:
x y = -5 +(5/4)x
0 -5
4 0
-8 -15
Now plot these three points (0, -5), (4, 0) and (-8, -15). Draw a dashed line through them. Because of the < symbol in y < -5 +(5/4)x, shade the area underneath the dashed line.

I got 12√ 2
PLZ CORRECT ME IF I AM WRONG PLZ AND THXS YOU
Step-by-step explanation:
It is the same thing as the average you add everything up then you divide by the number of numbers you added together
There 220 ways to select 3 of the 12 South American countries for the Geography assignment that solved by using the theory of combination in mathematics. The combination in mathematics is a way of choosing items from a set of items. The combination formula is n x (n-1) x ... x (n- k + 1) / k x (k-1) x ... x 1 where n is the number items in the set which is 12 and k is the amount you want to combine from the set which is 3.
