Answer:
(arranged from top to bottom)
System #3, where x=6
System #1, where x=4
System #7, where x=3
System #5, where x=2
System #2, where x=1
Step-by-step explanation:
System #1: x=4

To solve, start by isolating your first equation for y.

Now, plug this value of y into your second equation.

System #2: x=1

Isolate your second equation for y.

Plug this value of y into your first equation.

System #3: x=6

Isolate your first equation for y.

Plug this value of y into your second equation.

System #4: all real numbers (not included in your diagram)

Plug your value of y into your second equation.

<em>all real numbers are solutions</em>
System #5: x=2

Isolate your second equation for y.

Plug in your value of y to your first equation.

System #6: no solution (not included in your diagram)

Isolate your first equation for y.

Plug your value of y into your second equation.

<em>no solution</em>
System #7: x=3

Plug your value of y into your second equation.

Answer:
0 < t < 
After 1.67 days the stocks would be sold out.
Step-by-step explanation:
The price of a certain computer stock after t days is modeled by
p(t) = 100 + 20t - 6t²
Now we will take the derivative of the given function and equate it to zero to find the critical points,
p'(t) = 20 - 12t = 0
t = 
t =
days
Therefore, there are two intervals in which the given function is defined
(0,
) and (
, ∞)
For the interval (0,
),
p'(1) = 20 - 12(1) = 20
For the interval (
, ∞),
p'(2) = 20 - 12(2) = -4
Positive value of p'(t) in the interval (0,
) indicates that the function is increasing.
0 < t < 
Since at the point t = 1.67 days curve is showing the maximum, so the stocks should be sold after 1.67 days.
Answer:
25
Step-by-step explanation:
So the denominator can be simplified to 5⁴ →
and then the 3's cancel out and we are left with 5⁴
Now our new fraction is
which then simplifies to 25
