Answer:

Step-by-step explanation:

The student hasn't finished the factoring yet.

He still needs the step:

0 = (2x + 5)(x + 1)

The next step:

0 = 2x + 5, 0 = x + 1
x = - 2.5, x = - 1

g My Notes Water flows from the bottom of a storage tank at a rate of r(t) = 200 − 4t liters per minute, where 0 ≤ t ≤ 50. Find

Arada [10]

Answer:

4,200 liters

Step-by-step explanation:

The flow rate is given by:

$r(t) = 200 - 4t$

Integrating the flow rate expression from t=0 to t=30 minutes, yields the total volume that flows out of the tank during that period:

$\int\limits^{30}_0 {r(t)} = \int\limits^{30}_0 {(200 - 4t} )\, dt \\V=(200t - 2t^2)|_0^{30}\\V= (200*30 -2*30^2)-(200*0 -2*0^2)\\V=4,200\ liters$

4,200 liters of water flow from the tank during the first 30 minutes.

Beyonce and Guns N Roses had the two top-grossing North American concert tours for 2016, together generating $300 million in tic

ipn [44]

Answer:

Step-by-step explanation:

B + G = 300 (million)

G = B - 38 (million)

B + B - 38 = 300

2B - 38 = 300

2B = 300 + 38

2B = 338

B = 338/2

B = 169 million <=== Beyonce

G = B - 38

G = 169 - 38

G = 131 million <==== Guns N Roses

Solve for y 2x-5y=10

scZoUnD [109]

Answer:

y = 2/5x - 2

Step-by-step explanation:

Step 1: Write equation

2x - 5y = 10

Step 2: Solve for y

Subtract 2x on both sides: -5y = 10 - 2x
Divide both sides by -5: y = -2 + 2/5x
Rewrite: y = 2/5x - 2
