o-na [289]

a) (f+g)(x) = f(x) + g(x) = -4x + 5x = x

b) -9(x) = -9x? I have no idea what this means.

c) (f o g)(x) = (f(g(x)) = f(5x) = -4 (5x) = -20x

Rachel reads 1/5 of the pages of a book plus 12 pages on the first day.
kkurt [141]

Answer:

Let's say that the whole book have 5a pages.

First day: a + 12

Second day: (4a)1/4+15= a + 15

Third day: (1/3)[ 4a - (a+15)] +18= a + 13

Forth day: 70

So we get this:

(a + 12) + (a + 15) + (a + 13) + 70 = 5a

a + 12 + a + 15 + a + 13 + 70 = 5a

3a + 110 = 5a

3a - 5a = -110

-2a = -110

a = 55

5a = 5(55) = 275

So the total pages are in the book is:

275 pages
