You would first turn it into an improper fraction, to do this you leave the denominator(bottom number) then times it by your variable and add the numerator(top number)
Ex:
1 3/4x1/3= 7/12
Answer:
Correct option: C -> 2
Step-by-step explanation:
The first equation is:
And the second equation is:
From the second equation, we have:
Using this value of y in the first equation, we have:
Calculating the discriminant Delta, we have:
We have 
, so we have two real values for x, therefore we have two solutions for this system.
Correct option: C.
(If the system of equation is actually:
We would have:
We also have , so we have two solutions for this system.
Correct option: C.)
This answer would be D. x>1
The sign in the exponent: positive->increases, negative->decreases. Think that a negative sign implies 1/exponential and you'll clearly see the reason.
Answer:
Step-by-step explanation:
Always work from the inside out. That means we will deal with the parenthesis first: (4 - 1)
That gives us
2[32 - (3)³]. Next deal with the exponents. That gives us
2[32 - 27]. Next, the last set of parenthesis, which are actually brackets:
2[5] which then, finally, becomes 10
