2049342 increase by 3000, the result would be 2050342
Step-by-step explanation:
we solve for x
15x-(2/x)>1. /*x
15x^2 -2 > x. /-x
15x^2 -x -2 > 0
Solve the quadratic at zero
15x^2 -x -2=0
using the quadratic formula
x1,2 = [1+-sprt((-1)^2-4(15)(-2))]/2(15)
= [1+- sqrt (121)]/30
= [1+-11]/30
x1= 12/30= 2/5
x2= -10/30= -1/3
therefore this positive parabola is greater than zero or positive when
x< -1/3 and x> 2/5
We look at the tens place
20 is in the tens place
now look at the Ones place
6 is in the Ones place
If it is 5 or greater we round it to the next ten, if it is 4 or less we keep it the same
6 is greater than 5
The number will be rounded to 430

Answer:
Age of Jack is 9 years and his father's age is 43 years.
Step-by-step explanation:
The sum of Jack and his father's ages is 52.
Let the age of Jack = x
As per given statement "Jack's father's age is 2 less than 5 times Jack's age.
His father's age = 5x-2 ------(1)
So the equation will be
x + (5x-2) = 52 -----(2)
6x - 2 = 52
6x = 52 + 2
6x = 54
x =
x = 9 years
To find his father's age put the value in equation (1)
5(9) - 2 = 43 years
Age of Jack is 9 years and his father's age is 43 years.
