Tell whether the lines through the given points are parallel, perpendicular, or neither.
1 answer:
line 1: slope=2/3
slope: (4-0) / (7-1)
4/6 = <u>2/3</u>
line 2: slope= <u>6/-4</u>
slope: (6-0)/(3-7)
6/-4
These two lines are perpendicular

49. 100-36= how many girls in percent
= 64%
64%= 16 girls
64/100=16/x
cross multiply
1600=64x
x=25
Note that 80 is 16*5 and 96 is 16*6. Therefore, their sum is 16*5+16*6=16*(5+6), or 16*11. The sum is 176.
