Answer:
x will have to be 45 to make this true
Step-by-step explanation:
Answer:
-7
Step-by-step explanation:
Answer:
The correct answer is A) x = 1/4y^2
Step-by-step explanation:
Because the parabola opens to the side, we know that this is an x = equation. This allows us to eliminate both C and D.
Then we can determine that A is the correct answer due to the fact that it opens to the right. Negative lead coefficients always open to the left, so it could not be B
Answer:
the answer is incorrect though the first step is correct but the second step is wrong and so is the answer. the correct answer would be x raise to the power of 2by 5
Step-by-step explanation:
{x⁶/⁵⁻²/⁵} ¹/²= {x⁴/⁵}¹/²= x²/⁵
in the second step the power of the denominator must be subtracted from the power of the numerator using the law of indices then we would get the correct answer
9514 1404 393
Answer:
(x -y -1)(x +y)
Step-by-step explanation:
The expression can be factored by grouping.
x^2 -y^2 -x -y = (x^2 -y^2) -(x +y)
= (x -y)(x +y) -1(x +y)
= (x -y -1)(x +y)
_____
It is useful to know that a difference of squares is factored as ...
a^2 -b^2 = (a -b)(a +b)
