Answer:

The first table is a function.

Domain for the first graph: {1, 5, 10, 11, 14}

Range for the first graph: {6, 50, 150, 176, 266}

The second table is a function

Domain for the second graph: {0, 10, 20, 30, 40}

Range for the second graph: {0, 300, 600, 900, 1200}

Step-by-step explanation:

To tell whether if a relation is a function is to determine if the x values repeat itself. If the x value repeats itself, it is not a function. If it doesn't repeat itself, it is therefore a function. You can also tell if a relation is a function by doing the vertical line test. Draw a vertical line on a graph and if it hits more than one point, the relation is not a function. The domain are the x values while the range are the y values. When you're plotting the domain/range, make sure to put the numbers in order from least to greatest, use curly brackets instead of parentheses, and don't repeat the same numbers. So yeah a brainliest would be great but you don't have too.

What's The slope intercept form of: x - y = 7
Brilliant_brown [7]
Y=x-7 this is because you subtracted the x to both sides. Since y is a negative, you divide by -1 causing the -x to turn positive and the positive seven to be negative seven.

9n+21−3n−24 simplify
Thepotemich [5.8K]
Alright First you combine the like terms. 
9n - 3n = 6n 
21 - 24 = -3 

Rewrite the simplified equation
6n - 3 = 0

Solve for n 
6n = 3 
n = 3/6 
n = 1/2 

Ask if you need more help! :)
