Step-by-step explanation:
Adding 3 to both sides, we get
Dividing both sides by 2, we get
Hey, there!!
Given that:
y = 3x.........(i)

Putting the value of y in equation (ii)

=0


Therefore,
Either Or
(x+4)=0 (x-4)=0
x= -4 x= 4
so, x= (+ -)4
And if you wanna get value of y, just keep value of x in equation (i).
y= 3x
y= (3×4) or (3×-4)
y= 12 or -12
{As it is the quadratic equation it has two values. }

Answer:
L=8
Step-by-step explanation:
area of a rectangle = length x width
given:
area= 20 square units
width =2.5 units
find the length by substituting :
20=2.5 x L
L= 20/2.5=8
that's it :)
Answer:
neither
Here's how you know:
first, i'll simplify it so both are in slope-intercept form (y = mx + b).
x-3y=6
-3y = 6 - x
y = (1/3)x - 2
y=3x+4 is already in slope-intercept form, yay :)
these lines are neither parallel nor perpendicular.
The equations of parallel lines have THE SAME SLOPES (y = <em>m</em>x + b --> m would be exactly the same).
In contrast, perpendicular lines have NEGATIVE RECIPROCAL SLOPES (y = <em>m</em>x + b --> m would be <em>-1/m</em>).
<u><em>--> since the slopes of these match neither of these definitions, we know it must be neither.</em></u>
