Answer:
Step-by-step explanation:
Given is an equation in xy as xy =12
WE are to complete the coordinate table for xy =12
Let us give different values for x and find corresponding values of y

Note that x or y cannot equal 0 in this
So let us give other values
x y
12 1
6 2
4 3
3 4
2 6
1 12
-1 -12
-2 -6
-3 -4
-4 -3
-5 -2.4
-6 -2
-12 -1
I think the answer is 231.84
Answer:
Y = (-3) *X - 10
solution for Y =0 ---> X = -10/3
Step-by-step explanation:
Two points:
(Y0 ; X0) = (-4 ; 2)
(Y1 ; X1) = (-2 ; -4)
There is only one line which pass for both of them, his general expresion is:
y = a*x + b --- (1)
Calculating "a": is the pending of the line.

Calculating "b":
Since every point who belongs to the line satisfied the (1) expresion, we can use it for the point (Y1 ; X1) :

<u>Final expresion</u>
Replacing in (1): 
Solutions:
Answer:
x = -36
Step-by-step explanation:
Just multiply both sides of the equation with 3...,which tend to give a solution of,
; x = -12(3)
; x = -36

Step-by-step explanation:
First we need to get the slope of the perpendicular line
The slope of a perpendicular line is equal to the negative inverse of the slope of the given line
y

Now that we have the slope, we need to find the y-intercept.
To find the y-intercept, we need to plug-in values of
x
and
y
that the line passes through
