Answer:
B x^9 ∛ y
Step-by-step explanation:
(x^27 y) ^ (1/3)
x^27^(1/3) y^(1/3)
We can distribute the exponent a^b ^c = a^(b*c)
x^(27*1/3) y^(1/3)
x^9 y^(1/3)
Answer:
Is x = 4 a solution to the equation 6 = x + 2? YES
Is x = 4 a solution to the inequality 2x ≥ 9? NO
Step-by-step explanation:
Is x = 4 a solution to the equation 6 = x + 2? YES
we cans solve the equation 6=x+2 by clearing for x:
6 = x + 2
we move the +2 on the right as a -2 to the left:
6 - 2 = x
4 = x
this way we find that indeed x = 4 is a solution to 6 = x + 2.
Is x = 4 a solution to the inequality 2x ≥ 9? NO
Let's solve the inequality by clearing for x:
2x ≥ 9
we move the 2 that is multiplying on the left to divide on the right side:
x ≥ 9/2
x ≥ 4.5 ⇒ <u>x must be greater than or equal to 4.5</u>
thus, <u>4 is not a solution to the inequality</u> because 4 is less than 4.5
If you would like to solve 7x - (25x^2 + 12x), you can do this using the following steps:
7x - (25x^2 + 12x<span>) = 7x - 25x^2 - 12x = - 25x^2 - 5x
</span>
The correct result would be <span>- 25x^2 - 5x.</span>
Okay what we need to do first is add the whole numbers.
1 1/3 and 2 1/4 and the whole numbers are 1 and 2.
1+2 is 3.
Now to add 1/3 and 1/4, but something is wrong. We need the denominator to be the same.
So we need to find the same denominator.
We need to multiply the denominators by each other.
So the denominators are 3 and 4 of 1/3 and 1/4.
3*4 and 4*3 is both 12.
What you do to the bottom is what you need to the top the numerator.
1*4 is 4 and 1*3 is 3.
4/12 + 3/12.
Since the denominators are the same don't add those together keep them the same.
4/12 + 3/12 = 7/12
Now add the whole number 3 to 7/12
3 7/12 is your answer.
