Answer:
(-7,8), (2,1),(-8, -9), (-8,6)
Step-by-step explanation:
the x values repeat
The x values are not supposed to repeat to create a function
Y = 7x + 12.....x = number of tickets and y = total cost
and there are 4 tickets ordered (Frank and 3 friends)...so x = 4
y = 7(4) + 12
y = 28 + 12
y = 40 <=== so he paid 40 bucks for them
Answer:
The domain of function A is all real numbers. There is no function B listed.
Step-by-step explanation:
The domain is the set of all x values. This is the set of all numbers which are inputs to the function. Since function A is a linear function y = 3x + 2, it has all real numbers as its domain. It has no restrictions.
There is no function B listed to compare.
Good evening
Answer:
<em>a) the cost of one apple is €</em><em>0.9</em>
<em>b) the cost of one pineapple is €</em><em>5.4</em>
<em>c) the cost of two pineapples and six apples is €</em><em>16.2</em>
Step-by-step explanation:
Consider P the price of a pineapple
A the price of an apple
A pineapple costs six times as much as an apple means P = 6A
Mum paid €7.20 for one pineapple and two apples means P + 2A = 7.20
then
6A + 2A = 7.20
then
8A = 7.20
then
A = €0.9
Since P = 6A then P = 6×(0.9) = €5.4
the cost of two pineapples and six apples
= 2P + 6A
= 2P + P
= 3P
= 3×(5.4)
= €16.2
