Answer:
No, a value of t = 3.5 does not make any sense in this scenario.
Step-by-step explanation:
We are given the following information in the question:
where c is the cost and t is the number of tickets.
No, a value of t = 3.5 does not make any sense in this scenario.
Because the number of tickets are discrete value and cannot have decimal values.
The continuous variable can be expressed in decimal form.
Hence, t cannot have a value of 3.5
Although, cost is a continuous variable and may have decimal values.
Answer:
Ginny made a mistake in step 1 when she identified b = 31. It should be b=-31
Step-by-step explanation:
Ginny factored as shown:
ac = –180 and
b = 31
36(–5) = –180 and 36 + (–5) = 31
+ 36x – 5x – 30
6x(x + 6) – 5(x + 6)
(x + 6)(6x – 5)
b is the coefficient of x and from the trinomial , b=-31.
Therefore Ginny made a mistake in step 1 when she identified b = 31. It should be b = –31.
The correct steps are: :
ac = –180 and
b = -31
36(–5) = –180 and -36+5 = -31
