10p + 9 - 11 - p = -2(2p + 4) - 3(2p - 2)
9p - 2 = -4p - 8 - 6p + 6
9p - 2 = -10p - 2
9p + 10p = -2 + 2
19p = 0
p = 0 <===
Answer:
interchange the role of x and y
x=9y+5
x-5=9y
<u>x-5</u><u> </u>=y
9
so,f^-1(x)= <u>x-5</u>
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>9
