Answer:

Step-by-step explanation:

\frac{dy}{dx} =100-y\\integrating\\y=100y-y^{2} +c\\y(0)=100(0)-0^2+c\\25=c\\so ~y=100~y-y^2+25\\when y(0)=120\\c=120\\y=100~y-y^2+120

Evaluate the expression: -4a2 + 3ab - (2a + 3b) if a = 1/4 and b = -12
svetlana [45]

Answer:

Value of equation = 26.25

Step-by-step explanation:

Given:

Equation given

-4a² + 3ab - (2a + 3b)

Given value of a = 1/4

Given value of b = -12

Find:

Value of equation

Computation:

-4a² + 3ab - (2a + 3b)

By putting value of a and b

-4(1/4)² + 3(1/4)(-12) - [2(1/4) + 3(-12)]

-4(1/16) - (36/4) - [2/4 - 36]

-4/16 - 36/4 - [-142/4]

- 0.25 - 9 + 142/4

-0.25 - 9 + 35.5

Value of equation = 26.25
