Answer:
(1, -9)
Step-by-step explanation:
4x + y = -5
8x + 3y = -19
If we have to use elimination, that means we're going to add or subtract these two whole equations by each other so that we can cancel out one of the variables.
I think that we could easily turn 4x into 8x if we multiply the top equation by 2.
4x + y = -5 ---> 8x + 2y = -10
Now put them next to each other, and subtract to get rid of the xs.
8x + 2y = -10
- 8x + 3y = -19
------------------------
0x - y = -10 - -19
-y = 9
y = -9
Plug this back in to get x.
4x + y = -5
4x - 9 = -5
4x = -5 - -9
4x = 4
x = 1

Answer:
2.4×10^-6
Step-by-step explanation:
Your calculator can help you with this.
(8×10^-3)(3×10^-4) = (8·3)×10^(-3-4) = 24×10^-7
= (2.4×10^1)×10^-7 = 2.4×10^-6
<u>Answer:</u>
Half-life of uranium-238 
that of uranium-234
<u>Explanation:</u>
Half time of uranium-238 = 
years
Half time of Uranium-234 = 
years
To find how much times greater the half life of uranium-238 is from uranium-234
= 
=
=
Hence Uranium-238 is than Uranium-234
