Cost of one month of game play = $14
Step-by-step explanation:
Angir buys = 1 software package and 2 months of game play
Kenny buys = 1 software package and 1 months of game play
Cost of Software Package = $25
Total cost = $92
Cost of Game play =?
Total Purchase = 2 software packages and 3 months of game play
Writing in equation:
Let software packages = x and months of game play = y
2x+3y=92
If software package cost 25 i.e x=25, then
2(25)+3y = 92
50+3y = 92
3y = 92-50
3y = 42
y = 14
So, Cost of one month of game play = $14

Answer:
<h2>(1, 4)</h2>
Step-by-step explanation:
We write the polynomial in its factored form first.
We have then:
(x + 2) * (x + 1) * (x-4) * (x-5)
We now rewrite the polynomial:
(x ^ 2 + x + 2x + 1) * (x ^ 2-5x-4x + 20)
(x ^ 2 + 3x + 1) * (x ^ 2-9x + 20)
x ^ 4 - 9x ^ 3 + 20x ^ 2 + 3x ^ 3 - 27x ^ 2 + 60x + x ^ 2 - 9x + 20
We now add terms of the same degree:
x ^ 4 + (-9 + 3) x ^ 3 + (20-27 + 1) x ^ 2 + (60-9) x + (20)
x ^ 4 + (-6) x ^ 3 + (-6) x ^ 2 + (21) x + (20)
x ^ 4 - 6x ^ 3 - 6x ^ 2 + 21x + 20
Answer:
The polynomial sought is:
x ^ 4 - 6x ^ 3 - 6x ^ 2 + 21x + 20
<h3>
Answer:</h3>
60%
<h3>
Step-by-step explanation:</h3>
The percent change can be found from ...
... ((new value)/(old value) -1) × 100%
... (1520/950 -1) × 100% . . . . . . filling in your numbers
... (1.6 - 1) × 100% = 60% . . . . . . simplify
Attendance this year was 60% higher than last year.
a constant of proportionality is a number you have to multiply x by to get y.
y=kx is the equation that expresses the proportionality of x and y
the constant of proportionality is k, so k=-5
