The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
<h2>3</h2>
Step-by-step explanation:
The equation of line passing through the two points is 
When substituted,the equation becomes 
which when simplified is 
The line clearly passes through origin.
The distance between two points is 
Distance between origin and
is
.
Distance between origin and
is 
Scale factor is 
So,scale factor is 
which when simplified becomes 3.
The square root of 894916 is 946
A square root is a number that produces a specific number when multiplied by itself. Basically it's the same number multiplied by itself.
hope this helps:)
If 5y-10=0 it would equal 2. Add ten to both sides and then divide 5 to both sides which leaves you with y=2
