Answer:
its how much money he will get
Step-by-step explanation:
Answer:
6.25%
Step-by-step explanation:
We first begin by solving for the original price of the cell phone.
if 2400 = 125%
x = 100%
By cross multplying, we get
125x = 2400 * 100
x = 240000/125
x = 1920rs
To find the profit percentage on the new sale price, we repeat another set of equations
100% = 1920
x = 2040
1920x = 2040 * 100
x = 204000/1920
x = 106.25%
His new profit percentage is 6.25%
The answer would be 12 inches. I have the most faith in my answer.
ANSWER
The x-coordinate of the solution to the system of equations is 3.
EXPLANATION
The solution to the system of equations is the point of intersection of the straight lines that represents the given system.
From the graph the two straight lines intersected at:
(3,2)
Hence the solution to the system of equations is (3,2)
The x-coordinate of the solution to the system of equations is 3.

Delta equation is:

but we are interested in

because it determines the discriminant


which means that discriminant is positive :)
