2. f(x) = x - 2x² - 5 + 10x

=-2x² + 8x - 5

f'(x)= -4x + 8

4. y = 100(45x - 30 - 3x³ + 2x²)

= 100(-3x³ + 2x² + 45x -30)

= -300x³ + 200x² + 4500x - 3000

y' = -900x² + 400x + 4500

Two tanks hold a total of 55 gallons of a toxic solvent. One tank holds 4 gallons more than twice the amount in the other. How m
Serhud [2]

Step-by-step explanation:

If x is the volume of the first tank, and y is the volume of the second tank, then:

x + y = 55

x = 2y + 4

Solve the system of equations using either substitution or elimination.  Using substitution:

2y + 4 + y = 55

3y + 4 = 55

3y = 51

y = 17

Solve for x using either equation.

x + 17 = 55

x = 38

The first tank holds 38 gallons, and the second tank holds 17 gallons.

What is the equation of the line that has a y-intercept of 5 and is parallel to
victus00 [196]

Answer:

A) 2x + 5

Step-by-step explanation:

First, turn 2x - y = 16 into 2x - 16 = y by adding the <em>y</em> on both sides and subtracting 16 from both sides.

You'll see that option A is the only option that matches the original function that we're comparing to.

Graphs will always be parallel to each other if they have the same slope, and both these functions have the same slope of 2.
