Mrs. Eaton's class is participating in the "Box Tops for Education" campaign. On the first day, her
FrozenT [24]
The exponential model would take the form: 
y=Ae^{kt}&#10;
A, the initial value is 2, we will use 3 days and 8 tops to find k, or the rate.
8 = 2e^{k*3}
k =  \frac{ln(4)}{3}

Now, plugging in 6 days:
y = 2e^{ \frac{ln(4)}{3}*6}
y = 32

The linear would take the form:
y = mx+b
First the slope would be: (8-2)/(3-1) = 3
And to find b we could plug in the point (8,3):
8 = 3(3)+b
b = 8-9
b = -1
y = 3x-1
At x=6
y = 3(6)-1
y = 17

Thus, the exponential is almost double the result of the linear! Hope that helps.

Solve the elimination method
vlada-n [284]

Answer:

C)No Solution

Step-by-step explanation:

Given  2 equations

  • 4x-2y=1
  • 2x-y=2

Mentioned to solve using eliminations method

4x-2y=1

2x-y=2

Multiply second equation with 2

⇒second equation is 4x-2y=4

Now subtract second equation from 1st equation

4x-2y-(4x-2y)=1-4

4x-4x-2y+2y=-3

0+0=3

0=3

But 0≠3

Therefore there exists no solutions for the given pair of equations

Both equations are Parallel lines as they have the same slope

Someone help asap pls! answer AND explanation
AysviL [449]

Answer:

D.

Step-by-step explanation:

It is simply asking for the number that makes the equation untrue. So, all you need to do is plug in the various numbers below for w, and find out the incorrect number. Example with option D:

w-10≤16

27-10≤16

17≤16.

This makes the equation untrue, as 17 is not less than or equal to 16.

Hope this helps!
