Answer:

Ok from what your saying i would say your talking about a circle the formula to find the area of a circle is PiR^2

so the radius times radius times 3.14

Answer:

y = -1/2x + 1

Step-by-step explanation:

Slope-intercept form:

y = mx + b

Use two of the ordered pairs and find the slope:

m = (1-2)/(0-(-2)) = -1/2

y-intercept is 1 as point (0, 1) is given in the table:

b = 1

The line is:

y = -1/2x + 1

Given that (x+y+z)(xy+xz+yz)=18 and that x^2(y+z)+y^2(x+z)+z^2(x+y)=6 for real numbers x, y, and z, what is the value of xyz?

Answer:

Step-by-step explanation:

$(x+y+z)(xy+xz+yz)=18$ Equation 1

$x^2(y+z)+y^2(x+z)+z^2(x+y)=6$ Equation 2

What is the value of $xyz$ where each variable represents a real number?

Let's expand equation 1:

$(x+y+z)(xy+xz+yz)=18$

$x(xy)+x(xz)+x(yz)+y(xy)+y(xz)+y(yz)+z(xy)+z(xz)+z(yz)=18$

Simplify each term if can:

$x^2y+x^2z+xyz+y^2x+xyz+y^2z+xyz+z^2x+z^2y=18$

See if we can factor a little to get some of the left hand side of equation 2:

The first two terms have $x^2$ and if I factored $x^2$ from first two terms I would have $x^2(y+z)$ which is the first term of left hand side of equation 2.
