Answer:A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).
Step-by-step explanation:
Answer: y=4x-9
explanation: move the -4x over to the other side and it becomes positive 4x and -9 stays the same.
Answer:
![\sqrt[4]{x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E3%7D)
Step-by-step explanation:
First, let's examine our original statement.
Using exponent rules, we know that if we have 
, then simplified, the answer will be equivalent to 
.
So we can simplify this by adding the exponents 
and 
.
Converting into fourths gets us 
.
.
So we now have 
.
When we have a number to a fraction power, it's the same thing as taking the denominator root of the base to the numerator power.
Basically, this becomes
. (The numerator is what we raise x to the power of, the denominator is the root we take of that).

Answer:
E
Step-by-step explanation:
E is the only option where the answer would be a non--repeating answer, which is pretty much the definition of a rational number.
Answer:
