Answer: THE TABLE OF VALUES IS ATTACHED.
Step-by-step explanation:
Given the following equation:
You can solve for the variable "y":
Now you can give values to "x" and substitute each into the equation to find the corresponding value of "y".

With this values you can make the table shown attached.
If the item is 30% off, the new price is 0.7p because we want to know how much 70% of the original price was.
The exact answer would be 78/55, or 1 23/55
Answer:
The lines are perpendicular, meaning if they were to intersect, they would form four right angles.
Answer:
(3ab)/(2(b-a))
Step-by-step explanation:
The n-th term of an arithmetic progression is ...
an = a1 +d(n -1)
Then the value of n is ...
n = (an -a1)/d +1
The sum of an arithmetic progression is the product of the number of terms and the average of the first and last terms. In this sequence, the common difference d is ...
d = (b -a)
So, the sum is ...
Sn = (a +2a)/2·((2a -a)/(b -a) +1)
Sn = (3ab)/(2(b-a)) . . . . sum of the arithmetic progression

<u>Example</u>:
The sequence 1, 1.5, 2 has ...
a = 1, b = 1.5
Its sum is given by the above formula as ...
Sn = 3(1)(1.5)/(2(1.5 -1)) = 4.5/(2(.5)) = 4.5 = 1 + 1.5 + 2 . . . . yes
