The slopes of perpendicular lines are negative reciprocals
parallel lines have the same slope
First find the area of the leftmost rectangle:
A=l*w
A=4*2 (the 2 comes from 5-3)
A=8
Then find the area of the rightmost rectangle:
A=l*w
A=3*3 (the second 3 comes from 4-1)
A=9
So when you add 8 and 9, you get 17
Hope this helps
Step-by-step explanation:
3x -20= -2x +10
or,5x=30
or,X=30/5
or,X=6
Y= -2×6 + 10
= -2
therefore solution is (6, -2)
3 is 15% of what number...
3 = 0.15x
3 / 0.15 = x
20 = x <=== 3 is 15% of 20
