I think it might be 11x-8
I'm really sorry if that's wrong
Answer:
11 minutes
Step-by-step explanation:
Because she types only 140 words in 4 minutes so if you add
140+140=280
if you divide
140/4 you get 35
so every minute she types in 35 words. So multiply
11 times 35 and you exactly get 385.
By using the rules that the value inside square root can’t be negative and the denominator value can’t be zero, the domain for the given function is a) x<-1 and x>1 b) p≤1/2 c) s>-1.
I found the complete question on Chegg, here is the full question:
Write the restrictions that should be imposed on the variable for each of the following function. Then find, explicitly, the domain for each function and write it in the interval notation a) f(x)=(x-2)/(x-1) b) g(p)=√(1-2p) c) m(s)= (s^2+4s+4)/√(s+1)
Ans. We know that a number is not divisible by zero and number inside a square root can not be negative. In both the cases the outcome will be imaginary.
a) For this case the denominator x-1 can not be zero. So, x ≠1 and the domain is x<-1 and x>1.
b) For this case the value inside square root can’t be negative. So, p can’t be greater than 1/2 the domain is p≤1/2.
c) For this case also the value inside square root can’t be negative and the denominator value can’t be zero. So, s can’t equal or less than -1 and domain is s>-1.

Assuming that she goes every day of the month and one month has 30days:
Let the fee per class of Fit Fast be x.
Let <span>the fee per class of Stepping Up be y.
Let </span><span>the fee per month of Stepping Up be z.
Fit fast fee(if she does for this choice) - 30x
Stepping up fee</span><span>(if she does for this choice) - 30y + z
Im not sure of what the costs are as you did not state but here it is...hope this helps:)</span>
