The answer us 10.40 because you just - 1.05 feet
First, I'd simplify this problem by dividing every term by 2:
x^4 - 4x^3 + 5x^2 - 4x + 4 = 0
Then I'd think of the possible factors of that constant term, 4: They would be plus or minus 1, plus or minus 2, or plus or minus 4.
Let's try x = -4 as a possible root. Setting up and using synthetic division:
____________________
-4 / 1 -4 5 -4 4
-4 32
----------------------------
1 -8 37
This result is not helpful. So, try the possible root +4 instead:
________________
+4 / 1 -4 5 -4 4
4 0 20 64
----------------------------
1 0 5 16 68 4 is not a root because the remainder
(68) is not zero.
Try x = 2:
________________
+2 / 1 -4 5 -4 4
2 -4 2 -40
----------------------------
1 -2 1 -2 0
2 is a root because the remainder is zero.
Continue this process until you've found the other 3 roots.
Hint: Try the possible root x = -2 with the following coefficients:
____________
-2 / 1 -2 1 -2

Answer:
D.) x2 + (y + 1)2 = 1
Step-by-step explanation:
No explanation needed just need to say something here.
Answer:
m = 
Step-by-step explanation:
m - 
= 1 - 
Multiply through by 6 ( the LCM of 2 and 3 ) to clear the fractions
6m - 3(m - 1) = 6 - 2(m - 2) ← distribute parenthesis on both sides
6m - 3m + 3 = 6 - 2m + 4 , that is
3m + 3 = - 2m + 10 ( add 2m to both sides )
5m + 3 = 10 ( subtract 3 from both sides )
5m = 7 ( divide both sides by 5 )
m =
Answer:
y=1
Step-by-step explanation:
Start by plugging in -3 for x in the equation 2x+5y=-1 then solve for y.
2(-3)+5y=-1
-6+5y=-1 (add 6 to both sides)
5y=5 (divide both sides by 5)
y=1
