Answer:
<u>f(x) = 50 + 25(x - 1)</u>
Step-by-step explanation:
Let's write an equation to represent the function that will allow Damon to calculate the cost of his video game membership service:
Lifetime membership fee = $ 50
First video game is free
Then any video game purchased after = $ 25.
Let x to represent the total cost of the video game membership service, in consequence we can write the equation this way:
<u>f(x) = 50 + 25(x - 1)</u>
- If x = 1, then f(1) = 50 + 0 = 50
- If x = 2, then f(2) = 50 + 25 = 75
- If x = 5, then f(5) = 50 + 100 = 150
by angle sum property of triangle,
70+60+(x+60)=180
=> 190 +x = 180
=> x = 180-190
=> x = -10
The original gross margin is (2.50 / 1.00) - 1 = (2.5 - 1) = 1.5 = 150%
the cost increases 0.25, is an increase of (0.25 / 1.00) = 25%
in order to keep the same gross margin, you need to increase the sale price by 25%
2.50*1.25 = 3.125
Then the gross margin is (3.125 / 1.25) - 1 = (2.5 - 1) = 1.5 = 150% ( same as original )
Answer:
x = 
y = 
Jacobian value = 1/7
Step-by-step explanation:
Given data:
u = 2x -y
v = 3x + 2y
solving the system for x and y in terms of u and v
x =
y =
The value of the Jacobian = 1/7 ( solution attached below )
