Answer:
y = 2x + 4
Step-by-step explanation:
First find 2 points on the line to determine slope.
(0, 4) and (2, 8)
Slope = 
y = 2x + b
b = y - intercept
b = 4
y = 2x + 4
You need to solve 5 equations
1. 7x - 2.1 = 14.1
2. 7x - 2.1 = 30.9 and so on
1. 7x - 2.1 = 14.1
7x = 16.2
x = 2.314 so first number in the domain is 2.314
You can calculate the other 4 in the same way
2x +3y =70
2(0) +3y=70
3y=70
- -
3. 3
Y=23.3 repeating
The answer would be D.
In order for a table to represent a function, each x-value needs to pair with exactly one y-value and no more.
In the table shown here, none of the x-values repeat and all of them pair with a unique y-value which means that it’s a function.
Answer:
original price is x
discount is 10%
discounted price =10%of x
=10/100×x
=x/10
