Answer:
The last one.
Step-by-step explanation:
I think it's the last one because as x increases by one, y increases by a constant rate of 5. The others don't increase by a constant rate. (I don't know if this is right but I think it is!)
Answer:
Step-by-step explanation:
8x² - 5x + 3x(4 - 2x) =8x² - 5x + 3x*4 - 3x*2x
= 8x² - 5x + 12x - 6x²
Now add the like terms
= 8x² - 6x² - 5x + 12x
= 2x² + 7x
Answer:
Step-by-step explanation:
The general equation of a circle is , x² + y² + 2gx + 2fy + c = 0
Substituting the three points we get the following equations,
2g +14f +c=-50
14g - 2f + c =-50
16g +12f + c = -100
Solving these equations we get,
g =-4, f = -3, c = 0
Hence general equation of circle is,
x² + y² - 8x - 6y = 0
