I only found 1 solution when x=0 and y=0. Otherwise, other rational numbers don’t work. However I’m not 100% sure.

Answer:

f(x) = 13 when x = 10.

Step-by-step explanation:

$f(x)=\frac{x}{2}+8$

$f(10)=\frac{10}{2}+8$

$f(10)=5+8$

$f(10)=13$

Therefore, f(x) = 13 when x = 10.

PLEASE HELP MEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!!

To use the distributive property means to "distribute" the 6 among each term inside the parentheses. So we have to multiply the 6 by 5x and then multiply 6 by -3.

= 6(5x - 3)
multiply 6 by each term in parentheses

= (6 * 5x) + (6 * -3)
multiply inside each parentheses; remember a negative times a positive equals a negative

= 30x - 18

ANSWER: 30x - 18

Hope this helps! :)

What is the slope of the line?

yulyashka [42]

Answer:

Step-by-step explanation:

In simple terms, the slope of the line is $\frac{Rise}{Run}$

The equation states that the slope is how much the graph, rises goes up, divided by how much it goes across, to the right.

This graph goes up 3 units and goes to the right by 1 unit. Use the lattice points, the marked points, to make the decisions. You can pick any two points, and you will see that when simplified, it will equal 3.

This is because the graph is proportional.
