The equations of three lines are given below. Line 1: =−8x6y4 Line 2: =4y+3x7 Line 3: =y−34x7 For each pair of lines, determine whether they are parallel, perpendicular, or neither

If Jon is 3 years younger than Laura, then Jon's age is 35years.

Let the age of John be j

If Jon is 3 years younger than Laura, then;

Laura's age = j + 3

Based on the question, we are told that the product of their ages is 1,330, this can be expressed as:

j(j+3) = 1330

Expand

j²+3j = 1330

j²+3j - 1330 = 0

j²+38j-35j-1330 =0

j(j+38)-35(j+38) = 0

(j−35)(j+38) = 0

j = 35 and j = -38

j = 35

Hence Jon's age is 35years.
