From inspecting the graph, you can identify the y-intercept and the slope of the line shown.

The y-intercept is 200 gallons.
The slope is 

             75-200
    m = ------------- = -12.5 gallons/minute
               10 -  0

Thus, y = 200 gallons - [12.5 gallons/minute ]t

To answer the 2nd question, let t = 12 minutes and calculate y(12).

To determine how long it wld take to empty the tank, set the above formula equal to zero and solve the resulting equation for t.

nadya68 [22]

Answer:

SSS

The two triangles both share a side (the middle line), and it is shown that the other lines are congruent to each other. So all 3 sides are congruent, meaning SSS is the postulate that proves this.

Kendra sold 200 shares through her broker on June 8. The price per share was $22.10. The broker charged her a 0.5% commission on
KiRa [710]

<u><em>Answer:</em></u>

A. $4397.9

<u><em>Explanation:</em></u>

We are given that Kendra sold 200 shares and that the price per share was $22.1

<u>This means that:</u>

Total value = 200 * 22.1 = $4420

Now, we know that the broker charged 0.5% commission on the total value

<u>This means that:</u>

Broker's charge = 0.5% * 4420 = 0.005 * 4420 = $22.1

<u>Therefore,</u>

Kendra's return = Total value - broker's charge

Kendra's return = 4420 - 22.1 = $4397.9

Hope this helps :)

Solve. (K+1)(k-5)=0<br> Explin how to solve ???
Anna71 [15]
Alright remember, if any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0. 
k+1=0
k-5=0
Set the first factor equal to 0 and solve
k=-1
Set the next factor equal to 0 and solve
k=5
The final solution is all the values that make (k+1)(k-5)=0 true. 
k=-1, 5

Hope this helped you out :)
