Good evening ,
Answer:
x=0 or x=4
Step-by-step explanation:
x (2x-8)=0 ⇔ x =0 or 2x-8=0 ⇔x=0 or 2x=8 ⇔ x=0 or x=8/2 ⇔ x=0 or x=4.

It would take the pottery maker 2 hours to make a vase.
Answer:
parallel
Step-by-step explanation:
they have the same slope
look at them in terms of y=mx+b
first equation has slope of 1 (y=x+4)
second equation has slope of 1 also (y=x-3)
Consider the complete question is "The equation of the line is y=5x+1 and the equation of line is 2y-10x+3=0. How can you show that these two lines are parallel?"
Given:
Equation of is .
Equation of is .
To show:
The these line as parallel.
Solution:
We have,
...(i)
...(ii)
Equation (ii) can be written as
...(iii)
Slope intercept form of a line is
...(iv)
where, m is slope and b is y-intercept.
On comparing (i) with (iv), we get slope of line .
On comparing (iii) with (iv), we get slope of line .
Since, , therefore, lines and and parallel because slope of two parallel lines are always equal.
Hence proved.
