A and F are the only set of ordered pairs that work in both of the equations above. In order to find these you must place them into each equation and check for truth. Below is the work for A and F.
Ordered Pair A : (0,6)
y > 6x + 5
6 > 0 + 5
6 > 5 (TRUE)
y < -6x + 7
6 < 0 + 7
6 < 7 (TRUE)
Ordered Pair F : (-2, 18)
y > 6x + 5
18 > - 12 + 5
18 > -7 (TRUE)
y < -6x + 7
18 < 12 + 7
18 < 19 (TRUE)
Answer:
Im sure the answer is 4800, please correct me if im wrong
Step-by-step explanation:
My reasoning: Usually people would use 1/10 or anything like that, but here 3/7 was used. in order to find 10 percent you would divide by 10, correct, well I did the same with 7. (because you must find 1/7) The question was 3/7, so I multiplied 1400 by 3, and my answer was 4800. (sorry if this wasn't understandable, im the the best at explaining things)
The number of pencils and total cost are in a proportional relationship because the cost increases with the number of pencils.
Option D is correct.
Step-by-step explanation:
The cost of One Pencil = $3
The cost of 3 Pencils = $9
So, as the number of pencils are increasing, the total cost of pencils is also increasing because cost of 1 pencil is $3 and cost of 3 pencils increases to $9
So, we can say that the number of pencils and total cost are in a proportional relationship because the cost increases with the number of pencils.
Option D is correct.
