Problem 4
Answer: 47
------------------------
Work Shown:
f(x) = x^2 - 7x + 3
f(x) = (x)^2 - 7(x) + 3
f(-4) = (-4)^2 - 7(-4) + 3 ... replace each x with -4
f(-4) = 16 - 7(-4) + 3
f(-4) = 16 + 28 + 3
f(-4) = 44 + 3
f(-4) = 47

Problem 5
Answer: See the attached image for the table
------------------------
Work Shown:
Plug in n = 27 and we get...
C = 26 + 10*n
C = 26 + 10*27
C = 26 + 270
C = 296
The input n = 27 leads to the output C = 296. This means that 27 people will have the cost be $296
Do the same for n = 39
C = 26 + 10*n
C = 26 + 10*39
C = 26 + 390
C = 416
The input n = 39 leads to the output C = 416. This means that 39 people will have the cost be $416
and also n = 43 as well
C = 26 + 10*n
C = 26 + 10*43
C = 26 + 430
C = 456
The input n = 43 leads to the output C = 456. This means that 43 people will have the cost be $456
Answer:
24.56 minutes
Step-by-step explanation:
68,700 - (625 * x) = 53,350
We subtract 53,350 from both sides
15,350 - (625 * x) = 0
625x = 15350
x = 15350/625
x = 24.56
He needs to wait 24.56 minutes to get his car.
Answer:
Step-by-step explanation:
We are told that, Marley has already read 112.5 pages of the book.
Marley also plans to read at least 360 pages in all.
Now, let x be at least the number of pages Marley is let to read to achieve her goal.
This implies that
This means that Marley would have been reading at least 247.5 pages
Moreover, we are told that Marley reads 45 pages every hour.
Hence to find the minimum amoutnt of timeof time (let say y) she should devote fkr reading, we divide the number of pages she has left to read by 45.
This implies
