Mahesh is younger than John by 10 years. Sum of their present ages is 34 years. Find Mahesh’s present age.

M = 12 ; J = 22

Step-by-step explanation:

M = J - 10

J - 10 + J = 34

2J = 44

J = 22

M = 22 -10 = 12

Mahesh=a

John=b

a+10=b

a+b=34

a+a+10=34

2a=24

a=12

y=mx+b

step-by-step explanation:

m slope

b y-intercept

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
