Answer:

y - 7 = - \frac{5}{2} (x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - \frac{5}{2} and (a, b ) = (- 2, 7 ) , then

y - 7 = - \frac{5}{2} (x - (- 2) ) , that is

y - 7 = - \frac{5}{2} (x + 2)

Calculate dy/dx when xy^3 + y =3x
Yuki888 [10]
The answer is the option D.

You have to use implicit derivative

1) dy / dx = y'

2)

xy^3+y=3x

y^3+3xy^2y'+y'=3

(3xy^2+1)y'=3-y^3

y'= (3-y^3)/(3xy^2+1)

y'=(3-y^3)/(1+3xy^2)

Help I need help I don’t understand this question both of them
Advocard [28]

Answer:

N = Noel's Salary

N - 512.75 = Robert's Salary (512.75 less than Noel)

3(N-512.75) = John's Salary (3 times Robert's Salary)

Step-by-step explanation:Total Salary = 47645.25 = N + (N - 512.75) + 3(N-512.75)

47645.25 = 2N - 512.75 + 3N - 1538.25

47645.25 = 5N - 2051

49696.25 = 5N

9939.25 = N (Noel's Salary)

Robert's Salary = 9939.25 - 512.75 = 9425.50

hope this helped
