Can you please help me with #4-#5?I don't know how to find the answer.

Step-by-step explanation:

4:C(X) = 17x - 10, the first question wants you to find how much 5 ticket costs, so replace x with 5 so c(x)= 17(5)-10 which equals 75$

4a: 4a wants you to find how many tickets you can buy for  130$. So first replace the y or c(x) with 130 x, which gives 130=17x-10. Now we find x, first add 10 to both sides to cancel the -10, 140=17x, then divide 17 from both sides which gives 8.235, so we can buy 8 tickets.

4b: It is discreet because it cannot be broken down into decimals or fractions, since you cannot have a halve of a ticket.

4c: c(0) means the y-intercept

4d: the range is  7 to positive infinite

5:

x    y

0   -10

1    7

2   24

3   41

4   58

5  75

add the table and i will answer correctly

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
