Which point represents the order pair (2,-4)

Answers

Answer 1

Answer:

Answer: Second option.

Step-by-step explanation:

By definition, a Coordinate plane has an horizontal axis, which is called the x-axis and it also has a vertical axis,which is called the y-axis.

Observe in the picture given in the exercise that the point of intersection between the x-axis and the y-axis is the point $(0,0)$ , which is known as "Origin".

Given a point (x, y), "x" is the x-coordinate of the point and "y" is the y-coordinate of the point.

Then, given the following point:

$(2,-4)$

You can identify that its x-coordinate is:

$x=2$

And its "y" coordinate is:

$y=-4$

You can observe in the picture that this coordinates corresponds to the point B.

em saves at least 20% of what she earned for each week.is she earns $140 each week for 4 weeks wich inequality describes the total amount she saves

Answers

percent means parts out of 100
20%=20/100=2/10=1/5

20% of what she earned earned per week
'of' means multiply
20% of what she earned per week means
1/5 times what she earned per week

140 per week earned
1/5 of per week=saved
1/5 of 140=1/5 times 140=140/5=28

she saved this for 4 weeks
at least 28 saved per week for 4 weeks=28 times 4=102
she saved at least102 total
saved>$102

First, what you would do is multiply 140 and 20%. Which would give you: 28

Then you would multiply 28 by 4 and get 112

Hi there!

In order to use the elimination method, you have to create one variable that has the same coefficient. This is to be able to eliminate one variable and have a one variable equation (which you can then solve).

In your case, we'll have the "x" have the same coefficient by multiplying the top equation by 4 and the bottom equation by 2 :

4( -2x + 3y = -4) → -8x + 12y = -16

2( 4x - 2y = 16) → 8x - 4y = 32

Now that both of your equation have a variable with the same coefficient, you need to choose rather you need to add or subtract the equations in order to get rid of the variable (in this case we want to get rid of the "x").

In your case, you want to add both equation together which will give you :

8y = 16

Now that you only have one variable, all you need to do now is solve the equation for "y" :

8y = 16

Divide each side of the equation by 8

y = 2 → Your answer

There you go! I really hope this helped, if there's anything just let me know! :)
