It’s the first one since parallel means same slope
a. The first variable is x and the second variable is y.
b. The equations are
and 
Step-by-step explanation:
Step 1:
The first step is to define the variables. The variables can be any two symbols, letters, characters, etc.
Here let the first variable be x and the let the second variable be y.
So the variables are defined as x and y.
Step 2:
The sum of the given variables is 12.
The first variable + the second variable = 12,

The difference between the two variables is 4.
The first variable - the second variable = 4.

Step 3:
If we add both the equations we get,
and 
x = 8 and y = 4.
Answer:
22
Step-by-step explanation:
Answer:
The answer to your question is: y = -1/9 x - 40/9
Step-by-step explanation:
Data
A (-4 , -4)
B (5, -5)
Formula
m = (y2 - y1) / (x2 - x1)
y = mx + b
(y - y1) = m(x - x1=
Process
m = (-5 + 4) / (5 + 4)
m = -1 / 9
( y +4) = -1/9 (x + 4)
y + 4 = -1/9 x - 4/9
y = -1/9 x - 4/9 - 4
y = -1/9 x - 4/9 - 36/9
y = -1/9 x - 40/9
Answer:
D. diagonal = 20.10 cm
Step-by-step explanation:
Find the bottom diagonal using the length and width.
diagonal² = 8² + 12²
diagonal = √64+144
diagonal = √208
diagonal = 4√13
---------------------------------------------------------------------------------------------------------
Find diagonal of the rectangular solid:
diagonal² = (4√13)² + 14²
diagonal² = 208 + 196
diagonal = √404
diagonal = 20.10 cm
