To calculate the tax multiply $860 by .06 (6%) to get $34.40.
To calculate the total amount you'll pay add $34.40 to $860 to get $894.40.
When you don't use or write the percent right.<span />
Minust 5x both sides
7x-5x<5x-5x-8
2x<-8
divide by 2 both sides
x<-4
I don't have any pictures of graphs but a function that has a range of (2, infinity) means that hte lowers point (lowest y-value) is 2, and the height function keeps increasing (the y-value keeps increasing) to infinity.
Using the slope-intercept form, the slope is
2
/5 2/5.M=
25
