Answer: It would be (3)1
Step-by-step explanation:
Y = -2 x - 9
3 x - 4(-2 x - 9 ) = -8
3 x + 8 x + 36 = - 8
11 x = - 44, x = - 4
y = 8 - 9 , y = -1
This is a unique solution, the system is independent.
The next number would be 160
Answer:
x^2-10x+25
Step-by-step explanation:
(a+b)^2=a^2+2ab+b^2 so a=x and b=-5 so the expression is x^2-10x+25
To find the sum, add. To find the difference, subtract. It's simple terminology in mathematics. Hope I helped!
