The answer is choice B. The coordinate point CAN share the same y point but, CANNOT share the same x point
Answer:
see attached
Step-by-step explanation:
3x(x − 2)(5x + 2)
- (x − 2)(5x + 2) expand
- 5x² - 8x - 4
- 3x ( 5x² - 8x - 4) expand
- 15x³ - 24x² - 12x
You just subtract the number
Answer:
(2,-1)
Step-by-step explanation:
Multiply first equation by 2:
10x + 2y = 18
Subtract the second equation from this so that the 2y terms cancel:
10x - 3x = 18 - 4
7x = 14
x = 2
Plug into first equation to find y:
5(2) + y = 9
10 + y = 9
y = -1
The answer is (2,-1)
