2x - y = 8
x + 3y = 4
Answer:
x = 4, y = 0
Step-by-step explanation:
Two find x and y, we can simply solve one of the two equations for one of the variables, and substitute it into the other. That will provide one of the two values, which can then be plugged into either equation for the other value. Let's do it:
[tex]2x - y = 8\\y = 2x - 8\\\\x + 3y = 4\\x + 3(2x - 8) = 4\\x + 6x - 24 = 4\\7x = 28\\x = 4\\\\y = 2x - 8\\y = 2(4) - 8\\y = 0[/tex]
So x is equal to four, and y is equal to zero.

Properties of Exponential Function for Roots.
[tex]a^{\frac{m}{n}}=\sqrt[n]{a^m}[/tex]
The first one is wrong as 4^1/2 would equal √4 = 2
The second choice is correct.
The third choice is correct because ∛8 = 2 and √4 also = 2
The fourth choice is wrong because √8 = 2√2
The fifth choice is also wrong because 2^1/2 would be √2 while √32 is 2^5
The sixth choice is 3^3/2 which would equal √27 = 3√3 which is correct.
