If two functions are inverse of each other, they are basically switching the x- and y-axes.
Take for example, p(x)=2x, is a line passing through the origin with a slope of two. Its inverse, q(x)=x/2, is a line passing through the origin with a slope of 1/2, the reciprocal of 2. If you plot the two lines, you will notice that the two lines are symmetrical about y=x, or a 45 degree line from the x-axis.
This also explains y=x (which lines on the line of reflection) has its inverse also equal to y=x!
4*16-16 ? 4[24-2(4+8)]
Since 16+16+16+16 is the same as 4*16 I'l just make it 3*16 (because you minus 16 from it)
3*16 ? 4[24-2(4+8)]
48 ? 4[24-2(4+8)]
48 ? 4[24-2*12]
49 ? 4(24-24)
49 ? 4*0
49 ? 0
49>0
So it is a >
Hope this helps :)
Answer:
Its "B"
Step-by-step explanation:
The answer to this problem is $4.90
Mass of 1 sheet = (160 g/m^2)*(1/8 m^2) = 160/8 g = 20 g
mass of 25 sheets = (25 sheets)*(20 g/sheet) = 25*20 g = 500 g
