Step-by-step explanation:
x²/(x²-9) + 1/(x-3) = 1/(4x-12)
4x² + 4(x+3) = 1
4x² + 4x + 11 = 0
Since the discriminant is negative, there are no real solutions.
Answer:
x = -1 + 5y
Step-by-step explanation:
If you writing this equation in terms of x then the answer is correct, however, if there is a value for y, then you just need to sub it into y.
For example,
Find x when y = 3
x = -1 + 5(3)
= -1 + 15
= 14
This is basically saying "if you raise an exponent to another exponent, then you multiply the exponents. The product is the new exponent"
For example
Answer:
1/25
Step-by-step explanation:
5^4/5^6
Since we are dividing exponents with the same base, we subtract the exponents
5^( 4-6)
5^-2
We know that a^-b = 1/a^b
1/5^2
1/25
Answer:
C
Step-by-step explanation:
I substituted the x value with the different options. I kept doing that until the equation made sense.
