If you want to find the solutions for this you have to factor it. Since it's a second degree polynomial, you'll have 2 solutions. Factoring this using the quadratic formula, you'll get factors of (5x-8)(3x-4). Solving these for x you get x = 8/5 and x = 4/3.
It is d- the function is a line

Solve the equation 1/30 + 1/45 = 1/x
where x is the required time
multiply thru by 90x:-
3x + 2x = 90
x = 90 / 5 = 18
answer 18 minutes
The change from 10 to 11 or from 100 to 101 is 1 in each case.
In the first case, the percentage of change is 1/10 = 10%.
In the second case, the percentage of change is 1/100 = 1%.
The percentages of change are different because the bases from which the change is measure are different.
