Answer:
48 makes 58
Step-by-step explanation:
6 + 2 = 8 + 2 = 10 + 48 = 58
800 x 100 = 80000
80000 divided by 16 = 5000
5000 - 800 = 4200
His overall budget is $4200
15; it represents the one-time sign-up fee
The y-intercept can be found either on the graph where the line intercepts the y-axis, or b in the equation y=mx+b.
It represents the fee because it will be charged even if the number of months (x) is zero. 10 is the monthly fee because it is multiplied by x, the number of months.
Answer:
The number of cds to be sold to hit a weekly revenue of 1000 pesos is 25
Step-by-step explanation:
Here, we have the revenue function and we want to know the number of cds to be sold to hit a particular revenue value.
Mathematically from the question;
r = 2x^2 - 10x
in the question; r = 1000
so ;
2x^2 - 10x = 1000
divide through by 2
x^2 -5x = 500
so;
x^2 -5x -500 = 0
x^2 -25x + 20x -500 = 0
x (x -25) + 20(x -25) = 0
(x -25)(x + 20) = 0
x -25 = 0 or x + 20 = 0
x = -20 or 25
Since the number of cds cannot be negative, we only select x = 25 as the correct answer
