Please help, solve for x and n

1.

2.

Step-by-step explanation:

1.

Do cross multiplication

Distribute 3 through the parentheses

Move 3x to left hand side and change it's sign

Collect like terms

Divide both sides by 3

Calculate

The value of x is 1

---------------------------------------------------------------------

2.

Do cross multiplication

Distribute 2 through the parentheses

Similarly, distribute 6 through the parentheses

Move 12n to left hand side and change it's sign

Similarly, move 48 to right hand side and change it's sign

Collect like terms

Add the numbers : 48 and 2

Divide both sides by -10

Calculate

The value of n is -5 .

Hope I helped!

Best regards! :D

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
