4 hours for short or 4.333 hours
Answer:
Option B
Step-by-step explanation:
we know that
A line perpendicular to the x-axis is a line parallel to the y-axis
so
the equation of the line is of the form x=(+/-)a
The slope of the line is undefined
where
a is a real number
therefore
x=6 is a line perpendicular to the x-axis
Answer:
y=-8
Step-by-step explanation:
Let's solve your equation step-by-step.
15y−4=12y−28
Step 1: Subtract 12y from both sides.
15y−4−12y=12y−28−12y
3y−4=−28
Step 2: Add 4 to both sides.
3y−4+4=−28+4
3y=−24
Step 3: Divide both sides by 3.
3y
3
=
−24
3
y=−8
