Lubov Fominskaja [6]
5x - 9 > x*10^4
5x - 9 > x * 10000 I hope I'm reading the question correctly.
5x > 10000 x + 9
x > 10000/5 x + 9/5
x > 2000x + 1.8
0 > 1999x + 1.8
- 1.8 > 1999x
- 1.8 / 1999 > x
- 0.0009004 > x

-3x+5y=-9 and 4x+8y=12
insens350 [35]

-3x + 5y = -9

4x + 8y = 12

Simplify the second,

x + 2y = 3

Times three,

3x + 6y = 9

Add to the first equation,

11y = 0

y = 0

-3x + 5(0) = -9

x = 3

Answer: x=3, y=0

Answer:

C

Step-by-step explanation:

The easiest way to solve this would be to find the difference between the numbers. We can do -3-(-9) to find the difference of 6. We can then make sure this is true for the rest of the sequence by adding 6 to each number.

-9+6=-3

-3+6=3

3+6=9

9+6=15

Now that we've verified that this is true, we know the answer is C
