Answer:
There are some unknown characters in the answer list, so am not certain which letter. However, the expansion of (x^2 + y)^2 is:
x^4 + 2yx^2 + y^2.
Note: Am using the carrot - shift 6 - ^ to denote "to the power of".
Step-by-step explanation:
(x^2 + y)^2 = (x^2 + y) * (x^2 + y)
= (x^2 * x^2) + (y*x^2) + (y*x^2) + (y * y)
= x^4 + 2yx^2 + y^2
In words the answer is: x to the 4th plus 2 yx squared plus y squared.
Answer:
<u>y = -1 (x) -1</u>
Step-by-step explanation:
If you plug in the numbers from the coordinates into the equation, you will find that it's true.
-1 is x and 0 is y. Plug in the #s like so:
y = -1 (x) -1
0 = -1 (-1) - 1
0 = 1 - 1
0 = 0
Therefore, the equation above represents the line that passes through both these points.
