In the xy-plane, line e passes through point (3,-2) and intersect perpendicularly with line n that passes through points (0,3) and (3,5). What is the equation of line e? | [
"3x+2y+5=0",
"4x+3y-6=0",
"2x-3y-12=0",
"3x+2y-5=0"
] | D | If two lines intersect perpendicularly, we get -1 when we multiply two slopes together. The slope of a line n is (5-3)/(3-0)=2/3. Hence, the slope of a line e should be -3/2. Since it crosses (3,-2), if we calculate we get 3x+2y=5. Hence, the correct answer is A. | AquaRat_train |

Seven years ago Anoop was P times as old as Kiran was. If Anoop is now 17 years old, how old is Kiran now in terms of P ? | [
"17 - P/7",
"10/P + 7",
"P/11 +7",
"11.5P"
