Answer:
x2(y2 - 1) Now by using the identity a2 - b2. x2(y2 - 12) = x2(y + 1) (y - 1) Also, factorizing xy2 - 2xy - 3x by taking the common factor 'x' we get, x(y2 - 2y -

Answer:
Step-by-step explanation:
The two equations are 8x-10y=-23 and 9x+10y=-16.
If you plug them both into a graphing calculator, you will see that the point where they cross (the solution) is (-2.3, 0.5).
The answer is A.
Answer:
Since the equation is to the power of 4, the negative sign to the power of 4 will give a positive sign.
Answer:
Step-by-step explanation:
V of a cone V=3.14* r^2*h/3
942=3.14*r^2*9/3
r^2=942/(3.14*3)=100
r=sqrt100=10
