This is the concept of simultaneous equations, the question requires us to solve the system of equations given by:
2x+4y=38
10x+3y=105
from the top equation;
2x=38-4y
dividing through by 2 we get:
x=19-2y......(*)
substituting (*) in the second equation we get:
10x+3y=105
10(19-2y)+3y=105
190-20y+3y=105
collecting like terms we get:
-20y+3y=105-190
-17y=-85
dividing both sides by -17 we get:
(-17y)/(-17)=(-85)/(-17)
y=5
thus
x=19-2y
x=19-2*5
x=19-10
x=9
thus
x=9 and y=5

Find f(0)
From the piecewise function, we have the following as values of f(x):

If 

If 
f(0) implies that
and 
So, we make use of the first function, which is:

Substitute 0 for x in 



So, the expression becomes


<em></em>
<em>Hence, the value of f(0) is 14</em>

Base Area = 2 x 2 = 4 cm²
Volume = 4 x 3.5 = 14 cm³
Answer: 14 cm³
