Answer:
C. 2x^2 -8x +3 +1/(x +4)
Step-by-step explanation:
Synthetic division is useful for finding the quotient. Or, you can use polynomial long division. The result is the same, but synthetic division requires less writing.
I'll use x, y, and z for the numbers
x + z = y
x + y = 6 + z
3x - 2y = z
Substitute (x + z) for y in the second equation.
x + (x + z) = 6 + z and solve
2x = 6
x = 3
Rearrange another equation and substitute (3) for x.
(3) + y = 6 + z solve for y
y = 3 + z
substitute y in another equation
3(3) - 2(3+z) = z solve
9 - 6 - 2z = z
3 = -z
z = 3
going back to the first equation:
x+z=y
3 + 3 = 6
Answers:
x=3
y=6
z=3
check all equations to make sure it works for all equations
Answer:
The solution is (7, 6)
Step-by-step explanation:
You can find the solution of the system by multiplying the first equation by -3 and then adding together to get x to cancel.
-6x - 3y = -60
6x - 5y = 12
-----------------
-8y = -48
y = 6
Now that we have the y value, we can put it into either equation to find the x value.
2x + y = 20
2x + 6 = 20
2x = 14
x = 7
Therefore the point is (7, 6)
Answer:
10,077,696
Step-by-step explanation:
1. 6*6=36
2. 36*6=216
3. 216*6=1296
4. 1296*6=7776
5. 7776*6=46,656
6. 46,656*6= 279,936
7. 279,936*6= 1,679,616
8. 1,679,616*6= 10,077,696
