If i'm not wrong its distributing property of addition. <span />
Which of the following relations is a function? A. (0, 4), (-2, 6), (0, 3), (-7, 2) B. (8, 1), (-2, 4), (0, 1), (8, 2) C. (0, 4)

Answer: C
Step-by-step explanation:
C is a function because each of the inputs are distinct, meaning they only have one output each.
The other choices are not functions because at least one of the inputs corresponds to 2 or more outputs.
True
if you add an imaginary 0 to the numbers since its in the tenths place you would get 3,500
5(0) x 7(0) = 3,500
Answer:

Step-by-step explanation:
A vector perpendicular to the plane ax+by+cz+d=0 is of the form
.
So, a vector perpendicular to the plane x − y + 2z = 7 is
.
The parametric equations of a line through the point
and parallel to the vector
are as follows:

Put
and 
Therefore,

xy-plane:
Put z = 0 ⇒ t = -2 ⇒x = - 1 , y = 6
So, at point (-1,6,0)
yz-plane:
Put x = 0 ⇒ t = -1 ⇒ y = 5, z =2
So, at point (0,5,2)
xz-plane:
Put y = 0 ⇒ t = 4 ⇒ x = 5, z = 12
So, at point (5,0,12)
