3x² + xy2 – 3xy-y? >> 3x² - xy - y
line 1: = (3x² + xy2)+(-3xy – y?)
ANS 3x² - xy - y 《Correct》
line 2: = x(3x + y2) - y(3x – y2)
ANS 3x² - xy +2y²
line 3: = (x-y) (3x +y?)
ANS 3x² - 2xy - y²
If it incorrect, I'm sorry.
Answer:
Only Graph D
Step-by-step explanation:
A trend line indicates the general course (or average course) of the points on the graph. In Graph C, the general trend seems to intercept at a positive y-value. In Graph D, the trend will continue past the X-axis and intercept at the negative Y-axis.
Answer:
128
Step-by-step explanation:
If you would like to know which statement is true about the solution to the set of equations, you can calculate this using the following steps:
x + y = 2 ... y = 2 - x
2x + y = 4
_________________
2x + (2 - x) = 4
2x - x = 4 - 2
x = 2
y = 2 - x = 2 - 2 = 0
(x, y) = (2, 0)
The correct result would be: There is one solution.
