A point has the coordinates (0, k).

Which reflection of the point will produce an image at the same coordinates, (0, k)?

a reflection of the point across the x-axis
a reflection of the point across the y-axis
a reflection of the point across the line y = x
a reflection of the point across the line y = –x

Answers

Answer 1

Using reflection concepts, it is found that the correct option is:

a reflection of the point across the y-axis

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

The rule for a reflection of a point across the x-axis is: [tex](x,y) \rightarrow (x,-y)[/tex], thus [tex](0,k) \rightarrow (0,-k)[/tex]The rule for a reflection of a point across the y-axis is: [tex](x,y) \rightarrow (-x,y)[/tex], thus [tex](0,k) \rightarrow (-0,k) = (0,k)[/tex]. This is the correct option.The rule for a reflection of a point across the line y = x is: [tex](x,y) \rightarrow (y,x)[/tex], and thus, [tex](0,k) \rightarrow (k,0)[/tex].The rule for a reflection of a point across the line y = -x is: [tex](x,y) \rightarrow (-y,x)[/tex], and thus, [tex](0,k) \rightarrow (-k,0)[/tex].

Calculate the slope of a line through the points
(2, 1.5) and (-5, 36.5).

Answers

Answer:

35/-7

Step-by-step explanation:

you want to do the second y- the first y over the second X- the first x to GRT the slope

Answer:

35/-7

Step-by-step explanation:

To calculate slope, you use the slope formula: y2 - y1

                                                                              x2 - x1

So 36.5 - 1.5      

    -5 - 2            

And that equals 35/-7

Step-by-step explanation:

You first need to add up all the numbers on the chart, 36 + 29 + 54 + 31. You would then get 150. Divide 450 / 150 = 3. You multiply the amount of students chose pizza by 3 and you get 93. 31 * 3 = 93.

Find the value of X. | Please help me!!

Answers

Answer:

x=90 degrees

Step-by-step explanation:

A pentagon's angles should add up to 540 degrees. There are 6 angles shown, two are given ( the bottom two are right angles which are 90 degree angles). So 560 divided by 6 [angles] is 90[degrees]. So, each angle is 90 degrees.

6 sides meaning total angle is 720

2 angle already know = 2 x 90 = 180

so x = (720 - 180) : 4 = 135

If there are 40 boys and 60 girls in a room, fill out all of the possible ratios of boys to girls that could be made.

Answers

40+60=100. So one person equals 1%, meaning 40% are boys and 60% are girls. By simplifying, we will find that possible ratios below the value of 100 are 40:60, 4:6, 2:3, and 20:30.

Answer:

40:60  or 60:40

Step-by-step explanation:

This is the answer because a ratio looks like this

#:# <that just means a number by a number

and since the question is telling you to fill out all of the possible ratios of boys to girls that could be made.

There is really only one way you can write boys to girls but since they saying this try flipping the answer around like this:   60:40

Answer:

Start with what we know:

4(2x-3) = 28

Now we do rainbow property aka distributive property:

4*2x=8x

4*-3=-12

now we have:

8x - 12 = 28

we have to get 8x alone:

we will add 12 to both sides:

8x= 40

now we have to get x alone:

8x/8=x
