Step-by-step explanation:
Your question is incomplete, as the equations or graph or table(s) were not given.
However, I'll give a general way of solving this.
Take for instance, the equations are:
To do this, we start by equating both equations.
i.e.
Collect Like Terms
Take LCM
Cross Multiply
Make x the subject
Substitute 3/4 for x in
Hence:
18?
-18 divided by [-1/6]
is 18
hopefully that's what you were looking for.?!!
Answer:
x = 4
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 9²
x² + 1 = 81 ( subtract 1 from both sides )
x² = 80 ( take square root of both sides )
x = 
= 
= 
× = 4
