Answer:
The total cost was 81 dollars.
Step-by-step explanation:
If each person had to pay 27 dollars and there was only 3 people, then multiply those 2 numbers together. Then you will get your answer.
Answer: -8, 1
Step-by-step explanation: on the y axis you go to where the side is opposite so in this case 8,1 in on the right do u go to the left of the y axis and the is a negative x axis and positive y so u get -8,1
Answer ya so 1 is the answer
Step-by-step explanation:
Using a proportional relationship, it is found that the two equations that have the same constant of proportionality are givn by:
с 1 and 3
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the functions and constants are given as follows:
- 3. 8y = 6x -> k = 6/8 = 3/4.
Equations 1 and 3 have the same constants, hence option c is correct.

Hi,
(a+b)(a-b=a²-b²
Thus (9x)²-5²=81x²-25
