Answer:
(8, -22)
Step-by-step explanation:
The tables each contain four (x,y) points of a straight line. You can see that for every increase of x by 2, y decreases by 8 in the first one (observe 26, 18, 10 2), and decreases by 6 in the second.
If you continue the table with x=4, 6 and 8, you get y=-22 in both cases for x=8. That is the intersection, so the solution is (8,-22).
Added a graph. The equations are y=10-4x and y=2-3x respectively. Hope you understand a bit of this (brief) explanation.
Answer:
x = 12
Step-by-step explanation:
The line joining the mid points of the non- parallel sides is parallel to the parallel sides and is equal to half the sum of the parallel sides, hence
5x - 20 = (2x + 6 + 4x + 2)
= (6x + 8) ← distribute, giving
5x - 20 = 3x + 4 ( subtract 3x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
