Answer:
subtract 7 from both sides
2x < 7- 7
subtract 7 from 7 to get 0
2x < 0
product of two numbers is < 0 if one is > 0 and the other is < 0. since 2> 0, must be < 0.
x < 0
0.08
0.2
+
=
0.28 that’s how u work it out

Answer:
3000 books.
Step-by-step explanation:
Let x be total number of books.
3% is 3/100.
So:
3x/100=90
3x=9000
x=3000 books
F(x) = 2^x
(The ‘^’ means ‘to the power of’)
To find this function, you first need to notice that the y values are powers of 2, and you can tell because they are doubling each time x increases: 4 × 2 = 8, 8 × 2 = 16, etc.
Once you’ve noticed that they are powers of 2, you then need to find out which powers of 2 they are. The first y value is 4 which equals 2², and the second y value is 8 which equals 2³.
This means that the power is the x value, so you end up with f(x) = 2^x
I hope this helps!
