6 - 3x = 2x - 24

Answers

Answer:

x=6

Step-by-step explanation:

rearrange terms, subtract 6 from both sides, simplify, subtract 2x from both sides, simplify, divide both sides by -5, and finally you get 6.

Answer:

x=6

Step-by-step explanation:

6 - 3x = 2x - 24

move the x together and the numbers together

REMEMBER: when you move a something from one side of the equation (not including multiplication and division) to the other, change the sign in-front of it (+ or -)

NOW CONTINUE WITH THE PROBLEM -->

-3x-2x = -24 - 6

now subtract,

-5x = -30

and divide -30 by -5

Since there are 2 negative numbers, the result would be positive -->

and for x, you would get:

x=6

Plz help me on 8 and 9 plz answer and give and explanation I am supposed to show my work

Answers

Answer:

8) the ordered pair is a solution, 9) the ordered pair is not a solution

Step-by-step explanation:

8) if you plug in the values of x into the equation, which is 7, 7+9 equals to 16, which is the y value in the ordered pair

9) the same is for this question, if you plug in the x value into the equation, which is 5, 2(5)+8 is equal to 10+8 which is equal to 18. This isn't equal to the y value in the ordered pair

Answer:

8.) yes it is a solution because if plug in 7 for x and 16 for y you get 16=7+9 which equals 16

9.) No it is not a solutions because if you plug in 28 for y and 5 for x you 28=2(5)+8 and then when you multiply the 2 and the 5 you get 28=10+8 and 10+8 equals 18 and 28 and 18 are not equal

Can someone help me find the Slope to these to pleaseeee?

Answers

Answer:

Remember the slope formula:

m= y2-y1/x2-x1

11. (-1,3) (3,3)

= 3-3/3--1

= 0/4

m = 0

12. (1,3) (1, -2)

= -2-3/1-1

= -5/0

= undefined

For the future, know that the slope of horizontal lines is always zero and the slope of vertical lines is always undefined.

Which of these graphs is the solution set for the equation y = -3x - 2?

Answers

A because y=-3x-2 has these transformations
The negative before the 3 means the slope is going down
The 3 means it goes 3 down every time it goes right one, the number before the x is the slope and slope is rise over run, 3 = 3/1 so it would normally mean it goes up 3 every time it goes right one but because the 3 is negative it means the line goes down
The negative two at the end moves the line down two, if it were plus two the line would go up two, the number in this spot is what determines the vertical translation

Put it all together and you get the line has goes down 3 every time it goes right one and crosses the y axis at -2

Answer:
