the domain is a range of values of t (the x variable) that can give real values of y
Since the range ( y variable) is Rp= [0,100] ( round brackets mean excluding the two numbers while square means including ) since there are only 100 sheets of paper, no more no less
so the most t can be is when p=0, when t= 12.5, so domain is Dp= [0,12.5] after 12.5 min, there will be no paper left in the printer, so nothing can be printed
for D, sub t=7, so p(t) is the number of sheets left in the printer, you want to find the no. of sheets deducted so
p(t)=-8(7)+100
=100-15
=85
no. of pages in her report= 100-85= 15
Answer:
hence small rolls 60 and large rolls 70
Step-by-step explanation:
let club sold s small rolls
hence club sold s+10 large rolls
earning from small roll 3s
earning from large rolls 4.5(s+10)
hence
4.5(s+10) - 3s = 135
or 4.5(s+10) = 3s +135
3s +135 = 4.5(s+10)
3s +135 = 4.5s +45
4.5s +45 = 3s +135
4.5s -3s = 135-45
1.5s = 90
s = 90/1.5
s= 60
s+10 = 70
hence small rolls 60 and large rolls 70
It could be any time, but I would say 10. 10*10=100
hope it helps!
What is the solution to 5a+6 -4a=2(a-4)
Answer:
Solve for A by simplifying both sides of the equation, then isolating the variable.
a=14
