Answer:

A) (-6,3)

Step-by-step explanation:

-x-8y=-18

x +9y=21

Add the two equations together to eliminate x

-x-8y=-18

x +9y=21

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

y = 3

Now we need to find x

x +9y = 21

Substitute in y

x +9(3)  =21

x+27 = 21

Subtract 27 from each side

x+27-27 = 21-27

x = -6

What is the slope and y-intercept of x/3= -y+2 and how?????
Katarina [22]
Subtract 2 from both sides

then you get -y equals 1/3x -2 so you have to flip the sign of the entire equation because you can’t have a negative line

so you get y = -1/3x + 2

the y-intercept is (0,2)

the slope is -1/3x (aka -x/3)

Consider the following game: Roll a fair 6-sided die. You win if the result is greater than 4; otherwise, you lose. To play, you
dalvyx [7]

Answer:

-$1.33 or lose $1.33

Step-by-step explanation:

In this game, there are two possible outcomes.

- There is a 2 in 6 chance (rolling a 5 or a 6) that you win $8.

- There is a 4 in 6 chance (rolling a 1, 2, 3 or a 4) that you win nothing.

Note that for any outcome, you start off paying $4 to play.

The expected value of this game is:

E(X) =\frac{2}{6} *\$8+\frac{4}{6}*\$0-\$4\\E(X) = -\$1.33

You are expected to lose $1.33 per play.

What's the difference between tens and tenths
Margarita [4]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Tens are 'whole' and tenths are 'decimal'

[i'll give an example so it makes more sense]

1846.97

In this number, the tens value would be '4' or forty

The tenths value would be '9' or 9 tenths (0.9)

Any further queries, feel free to ask me.

➶ Good Luck (:
