I think the answer is x= 11 but im not sure <span />
Answer:
8
Step-by-step explanation:
0 = –x^2 + 4x – 2
This is of the form
ax^2 +bx +c
a = -1 b = 4 x = -2
The discriminant is
b^2 -4ac
4^2 - 4(-1)(-2)
16 - 8
8
To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.



_______________


___ ____

(rounded)
Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.




So, your final answer would be (3.29, 4.87).
The amount of material/ number of pillows made
16/12 = 4/3 = 1 1/3
So the answer lies between integers 1 & 2
780,120?
