 2x - 3y = 9   ⇒ -10x + 15y = -45
-5x - 3y = 30 ⇒ <u>-10x -   6y =   60</u>
                                      <u>9y</u> = <u>15</u>
                                       9      9
                                       y = 1 2/3
                     2x - 3(1 2/3) = 9
                               2x - 5 = 9
                               <u>     +5  +5</u>
                                     <u>2x</u> = <u>4</u>
                                      2     2
                                       x = 2
                                 (x, y) = (2, 1 2/3)

If your in algebra 1 then i'm pretty sure you subtract the 2x and that cancels and subract the 2x with the 9 and you have -3y= -2x+9 so you divide -3 to the -3y, the -2x and positive 9 and your answer will be y=2/3x-3

KIM [24]
You just add all the numbers together:
3 1/8+ 4 1/2+ 4 1/4
=25/8+9/2+17/4
=25/8+36/8+34/8
=95/8
=11 7/8

Ugh.. did you type in the numbers correctly? My guess would be it was meant to be B tho :)

A jar contains 30 red, 30 blue, and 60
kiruha [24]

The probability of picking red button is \frac{1}{4}

<u>Solution:</u>

Given, A jar contains 30 red, 30 blue, and 60 white buttons.  

You pick one button at a random choice,  

We have to find the probability that it is red button.

Now, total number of buttons = 30 + 30 + 60 = 120 buttons.

Number of favourable cases for red button = 30 red buttons.

The probability of an event is given as:

\text { probability of a event }=\frac{\text { favourable ways to pick red }}{\text { total possiblities }}

=\frac{30}{120}=\frac{1}{4}

Thus the probability that it is red is \frac{1}{4}

Please help if u can
wolverine [178]

Answer:

f(x) -> 2 as x -> -∞ and f(x) -> ∞ as x -> ∞

Step-by-step explanation:

f(x) -> 2 as x -> -∞ and f(x) -> ∞ as x -> ∞

*this is because the graph shows that the y value cannot pass by 2 as the x value constantly decreases and as x is increasing, there is just an arrow showing that the graph is constantly going up and therefore going to ∞
