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!
(0,0) and (1,0) are the x-intercepts.
Answer:
side a = 24
Step-by-step explanation:
∡a = ∡b =>
isosceles triangle =>
side a = 24
Step-by-step explanation:
We have got the lines :
Both lines intercept the x-axis in the point :
In all point from x-axis the y-component is equal to 0.
We replace the I point in the lines equations:
From the first equation :
From the second equation :
Then 
Finally :
y = ax + b and y = cx + d have the same x-intercept ⇔ad=bc

Suppose the 3 squirrels all wanted to store acorns for the winter.
Depending on how motivated. Each squirrel was they would end up with
different amounts. For instance suppose the brown squirrel took 4 trips,
the gray squirrel took 2 trips, and the black squirrel took 2 trips.
The Brown squirrel would end up with 8 acorns, the gray squirrel would
have 6 acorns and the black squirrel would have 10. Between them they
took every one of the 24 acorns.
Hope it helps.
