Alexis can wash a total of 14 windows in 1 hour
<h3><u>Solution:</u></h3>
Given that Alexis washes
windows in
hours
<u><em>To find: </em></u>number of windows washed in one hour
To simplify the calculations we will convert the given mixed fraction to improper fraction

Hence, to wash 10.5 windows, Alexis takes 0.75 hours
Let "n" be the number of windows washed in 1 hour
10.5 windows ⇒ 0.75 hours
"n" windows ⇒ 1 hour
By cross-multiplication we get,


Thus Alexis can wash 14 windows in one hour
F(x)= 2x-6
Y=Mx+b
B= y intercept= -6
M= how many times it went up so 2 times
Hope this helped :))
