Make sure that you put a line over the 1s on #2
I can not see the fraction on #1
Answer: no
Step-by-step explanation:
Linear functions are straight lines and are also written in the form y=mx+b
Well, 20% is equivalent to (1/5). So, you'd put 50 in the numerator and 5 in the denominator. (50/5) is equal to 10. Then you'd take that value and subtract it from your original value. [ 50 - 10 = 40 ]. 40 Students were at school that day.
we are given

For finding inverse function , we do following steps
step-1:
Set f(x)=y

step-2:
Switch x and y

step-3:
now, we can solve for y

Multiply both sides by 9y-2



Add both sides by 2x


now, we can divide both sides by 9x

so, we get inverse function as
