Answer:
The first one, an=n-2
Step-by-step explanation:
The slope of the linear equation is 1. You can notice the y intercept would be -2, therefore the equation is an=n-2.
y = (2x-4)/3
to find the inverse change x and y then solve for y
x = (2y-4)/3
mutiply by 3 on each side
3x = 2y-4
add 4 to each side
3x+4 =2y
divide by 2
(3x+4)/2=y
h^-1 (x) = (3x+4)/2
Choice C
Answer:
$145.80
Step-by-step explanation:
The original cost of the product was $90. There was a 162% markup. In order to get the selling price, I like to take away 100 percent and simply add original price+(original price*62%). After taking away 100%, I am left with 62%. I then multiply the original cost ($90) by the remaining percent (62%), getting 55.8. Following the steps that I originally wrote, I now add 90 to 55.8, getting 145.8.
