F(x)=x2+4=2*2+4=4+4=8 when x=2
f(x)=x2+4=0*2+4=4 when x=0
f(x)=x2+4=1*2+4=6 when x=1
Have a nice day!!! ^^
Please, use ( ) around fractional coefficients:
<span>1/3x-9y, 6/5x-15y should (probably) be written as (1/3) - 9y and (6/5)x - 15 y.
The LCD here is 3(5) = 15.
Mult. </span><span>1/3x-9y and 6/5x-15y by 15, and then divide the result by 15:
</span>15 [ (1/3)x - 9y and (6/5)x - 15 y ]
---------------------------------------------
15
This simplifies to:
5x - 135y and 18x - 225y
------------ --------------
15 15
These fractions are equivalent to the original ones, but now the common denominator, 15, is evident.
