Which coordinate pair represents the reflection of (–4, 6) across the x-axis?
liubo4ka [24]

Answer:

(-4, -6)

Step-by-step explanation:

when you reflect a point over the x axis, the only value that changes is the y-axis, or the height of the point. because the original point is at a height of +6, flipping over the x-axis would make it -6

think of it this way:

reflecting across the x-axis creates symmetry, so you pretty much copy the the steps you would do to reach the original coordinate pair but reverse it

so since you go up 6 from the x axis in the original coordinate pair (-4,6), you would go down 6 when reflecting over the x-axis

8. In a word game, you choose a tile from a bag, replace it, and then choose another. If there are 28 vowels and 12 consonants,
sasho [114]

Answer:

The probability that you will choose a consonant and then a vowel is 0.21....

Step-by-step explanation:

Total no of tiles = 28 + 12 = 40

First you should choose a consonant = 12/40

Second you should choose a vowel = 28/40

So the probability you choose a consonant and then a vowel:

= 12/40 * 28/40

=336/1600

=0.21

So the probability that you will choose a consonant and then a vowel is 0.21....
