Answer:
$12.50
Step-by-step explanation:
Let x = the cost of the food without the delivery fee.
The delivery fee can be represented as 0.10x.
Keep in mind that the cost of the food plus the delivery fee equals $13.75.
Therefore, your equation will look like: 13.75 = x + 0.10x
x + 0.1x = 1.10x
So, 13.75 = 1.10x
This means that x = 13.75/1.10
x = 12.5 = $12.50
Answer: ok.....
Step-by-step explanation:
Sin (squareroot2/2) is the same as the angle 1/4×Pi which is the same as 45degrees
Just from the figure,
As x decreases, y approaches 0
As x increases, y increases without bound
Answer:
The solution of the system is at point (1,6) and (7,0).
Step-by-step explanation:
Given : System of equation
and 
To find : Solve the system of equation?
Solution :
We solve the equation graphically as the intersection points give you the solution of the system.
The equation given is one linear and one parabolic.
(1)
is a linear equation in red line passes through (0,7) and (7,0).
(2)
is a parabolic equation in blue line passes through (-1,0) and (7,0)
The intersection point of the equations are (1,6) and (7,0).
<u>Refer the attached figure below.</u>
Therefore, The solution of the system is at point (1,6) and (7,0).
