Answer:
The correct option is C) –x + xy – 7y.
Step-by-step explanation:
Consider the provided expression.
Rearrange the expression so, that like terms comes together.
–3x + 2x + 2xy – xy + 4y – 11y
Now, add the like terms as shown below:
x(–3 + 2) + xy(2 – 1) + y(4 – 11)
Now, perform the operation inside the parentheses.
x(–1) + xy(1) + y(–7)
Open the parentheses.
–x + xy –7y
Now, compare with the provided options.
By comparison it can be concluded that the correct option is C).
Hence, the correct option is C) –x + xy – 7y.
1/4x^2 = -1/2x + 2.....multiply everything by 4
x^2 = -2x + 8
x^2 + 2x - 8 = 0
(x + 4)(x - 2) = 0
x + 4 = 0
x = -4
x - 2 = 0
x = 2
solutions are : x = -4 or x = 2
Answer:
it means that you have to multiply all those things
Step-by-step explanation:
then you'll get the answer which is hard
you have to look at a graph in order to figure out the answer so it would be... -9, 7 for the top left
9, 4 for the top right
0, -3 for the coordinatate in the middle
-5, -2 for the bottom left
and 1, -8 for the bottom right
