Review the work showing the first few steps in writing a partial fraction decomposition. StartFraction 2 x squared + 15 x + 19 Over (x + 4) cubed EndFraction = StartFraction A Over x + 4 EndFraction + StartFraction B Over (x + 4) squared + StartFraction C Over (x + 4) cubed EndFraction

2x2 + 15x + 19 = A(x + 4)2 + B(x + 4) + C

2x2 + 15x + 19 = Ax2 + 8Ax + 16A + Bx + 4B + C

Which system of equations can be used to determine the values of A, B, and C?

Step-by-step explanation:

Given

Required

Find A, B and C

Rearrange the expression

To do this, we simply compare the expressions on both sides of the equation.

So, we have:

--- (1)

--- (2)

--- (3)

Divide both sides by x² in (1)

Divide both sides by x in (2)

Substitute 2 for A.

Make B the subject

Substitute 2 for A and -1 for B in (3)

Make C the subject

0.5 meters per second

step-by-step explanation:

the average speed between 2 seconds and 8 seconds is 0.5 meters per second.

hope this ! mark brainliest!

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
