A function means that “for only x, there is one and only one y”. If you look at these sets, you can see that the statement is true for A, but not for B. In B, you can see that an x-value of 4 has two y-values (2 and -2) and a value of 9 also has two y-values. Therefore, only A is a function.
Answer:
508.68 or 508.7
Step-by-step explanation:
V=1/3(3.14)(9)^2(6)
(3.14)(81) x 6
(3.14)(486)
1/3(1526)
(divide by 3)= 508.68
-4.
The equation for a line is y-y₁=m(x-x₁)
Using the following:
x₁= 1
x₂= -2
y₁= 1
y₂= 4
and slope, or m, is (x₂-x₁)/(y₂-y₁),
You can now fill out the equation!
y-(1)=-1(x-(1))
y= -x+2
And solve by substituting the 6, or x₃, into the equation to find the corresponding y value:
y= -(6)+2
y= -4
Therefore,
n=-4
