Answer:
x=-0.08 and y=2.92
Step-by-step explanation:
123x + 2(x+3) = -4 y = -0.08 + 3
123x + 2x + 6 = -4 = 2.92
125x + 6 = -4
125x = -10
x= -0.08

Answer:
B
Step-by-step explanation:

So, Both lines are perpendicular
Step-by-step explanation:
We need to identify if lines:
Line 1: (8,12)(7,-5)
Line 2: (-9,3)(8,2)
are parallel, perpendicular, or neither?
- Lines are parallel if they have same slopes i.e slope 1= slope2
- Lines are perpendicular if their slopes are negative inverses of each other i.e slope 1= -1/slope 2
The formula used to find slope is:

Finding Slope of Line 1:
The points are: Line 1: (8,12)(7,-5)

Putting values in the formula:





So, Slope of line 1 is 17
Finding Slope of Line 2:
The points are: Line 2: (-9,3)(8,2)

Putting values in the formula:




So, Slope of line 2 is 
Since 
So, Both lines are perpendicular
