= 7(x^2 + y^2 - 4x + 6y - 5)= 0
= 7( (x - 2)^2 - 4 + (y + 3)^2 - 9 - 5) = 0
= 7[ (x - 2)^2 + (y + 3)^2 - 18) = 0
center is at (2,-3) and radius = sqrt18 = 4.24 units
2x -6x + 27= 4-3x +11
2x-6x+3x= 4+11-27
-1x= -12
x=12
Answer:
Step-by-step explanation:
1. The polynomial must have the following zeros:
2. This means the following:
3. Multiply each term. The product of the multiplicaction is equal to zero. Then:
4. and are conjugates, therefore, you have:
5. Apply the Distributive property. Then, you obtain:
6. The polynomial of degree 4 and zeros −4, 0, 4 and 6 is:
Answer:
x=-1
Step-by-step explanation:
-2x+3=-3x+2
-2x+3x=2-3
x=-1
