Answer:
-√64: rational
15 pi: irrational
46.86 repeated: rational
15/19: rational
-2√6: irrational
Step-by-step explanation:
From the picture that I used, I was able to find out which ones were rational and irrational.
-√64: rational because it equals to -8
15 pi: has "pi" in it
46.86 repeated: as long as it's repeated, it's rational
15/19: fractions are usually rational
-2√6: √6 is cannot be rationalized

Step-by-step explanation:
<em>Hey there!</em>

Well to find the solution the the given system,
3y - 2x = -9
y = -2x + 5
So to find x lets plug in -2x + 5 for y in 3y - 2x = -9.
3(-2x + 5) - 2x = -9
Distribute
-6x + 15 - 2x = -9
-8x + 15 = -9
-15 to both sides
-8x = -24
Divide -8 to both sides
<u>x = 3</u>
<u />
Now that we have x which is 3, we can plug in 3 for x in y = -2x + 5.
y = -2(3) + 5
y = -6 + 5
<u>y = -1</u>
<u><em /></u>
So the solution is (3,-1).
