In a certain fraction, the denominator is 2 less than the numerator. if 1 is added to both the numerator and denominator, the resulting fraction is equal to 4/3. find the original fraction.

  7/5

Step-by-step explanation:

Adding 1 to numerator and denominator will not change the difference between them. In order to make a fraction equal to 4/3 with a difference between numerator and denominator of 2, we can multiply 4/3 by 2/2:

  4/3 = 8/6 = (7+1)/(5+1)

The original fraction must be 7/5.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
