Simply plug 7 for each value of x
f(7)= -3(7) + 6
f(7)= -21 + 6
f(7)= -15
1) =total seats =32560
give away tickets=4500
amount of each ticket=$9.50 each
to get the remaining ticket you subtract give away tickets from total seats
=32560-4500 =28060
remaining tickets are=28060
so you multiply remaining tickets by the amount they sold each of the tickets
=28060×$9.50 =$266570
so the answer is $266570
2) paperback book is sold for = 25¢ each
hardcover book is sold for=$1.25 each
total number of the paperback book = 54
total number of the hardcover book =163
so you need to multiply paperback book by the amount it sold each and you still do the to hardcover book
=25¢×54=$13.5
=$1.25×163=$203.75
then we add the the total together =
=$203.75+$13.5= $217.25
so the answer is $217.25
3)$14.50 per hour if she works for 35hours
she gains extra $1.5per hour if she works 48 hours
we are going to subtract 35 hours from 48 hours to get the extra time she worked
=48-35= 13
so we multiply 13 by $1.5 =$19.5
so we multiply 14.50by 35= $507.5
so we add = $507.5+$19.5= $527
so the answer is $527
4) airfare is $398.60
her room is $115.70 per night ×2
cab =$40
add up =$398.60+$231.4+$40=$670.00
so the answer is $670.00
I hope this helps you
Answer:
What the question
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Switch x for 6:
(6)-8=-2
Subtract 6 from 8:
-2=-2
-2 does equal -2 so 6 is a solution.
Answer:
Step-by-step explanation:
None of them
A has (5, 13) and (5,17) That's 2 y values for the same x. You can't have that. A fails the vertical line test.
B has two y values for x = - 3. The two values are (-3,-1) and (-3,1). Both values eliminate B as an answer.
C fails because -1 has 2 y values (-4,52) and (-4,?) We can't see the bottom, but it is another value. There is an x value we cannot see that has 45 as an answer along with -7 for x. That's fine.
If there is a D answer, you almost have to choose it. There isn't much choice.
