Answer:
x = 6
Step-by-step explanation:
Given
+ 4 = 7 ( subtract 4 from both sides )
= 3 ( square both sides )
2x - 3 = 3² = 9 ( add 3 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
25, 2, and 3 are rational.
is irrational.
x / x^-4 = x ^(1 - -4) = x^5
y^2 / y^-6 = y^(2 - -6) = y^8
So the answer is x^5 / y^8
or x x^4 / y^2y^6 which is the second answer choice
1. x + 2y -3 =0.
2. x/2 + y/9 = 1/3.
3. 4x-y+7=0.
4. x + y/2 = -1/2.
5. a. 3x-y-1=0.
b. x - y/3 = 1/3.
