Answer:
umm what do you mean can like you explain
<h3>

are the slopes of perpendicular lines</h3>
<em><u>Solution:</u></em>
We know that,
Product of slope of a line and slope of line perpendicular to it is always equal to -1
<em><u>Option 1</u></em>


Thus, these are not the slopes of perpendicular lines
<em><u>Option 2</u></em>

This option satisfies the slopes of perpendicular lines
<em><u>Option 3</u></em>

Thus, these are not the slopes of perpendicular lines
<em><u>Option 4</u></em>
2 and 2
Product = 2 x 2 = 4
Thus, these are not the slopes of perpendicular lines
(b)+(b+45)=215
b = # of boys
there are 45 more girls than boys and 215 students total.
minus 45 on both sides leaving you with
(b)+(b)=170
combine like terms leaving you with
2b=170
divide both sides by 2
b=85
there were 85 boys
85+45=130
(the 45 for the # of girls more than boys)
there were 130 girls.
Is there a picture of some sort of angle or parallelogram? Because there isn't enough information to solve the question with only this. Sorry!
