Answer:
16
Step-by-step explanation:
Subtracting the given expressions, that is
3b² - 8 - (b(b² + b - 7) ) ← simplify parenthesis
= 3b² - 8 - (b³ + b² - 7b) ← distribute parenthesis by - 1
= 3b² - 8 - b³ - b² + 7b ← collect like terms
= - b³ + 2b² + 7b - 8 ← substitute b = - 3
= - (- 3)³ + 2(- 3)² + 7(- 3) - 8
= - (- 27) + 2(9) - 21 - 8
= 27 + 18 - 21 - 8
= 16
You were using it for 6 hours because 70-25 is 45 and if you divide 7.50 and hour and 45 it’s 6

Answer:
Option D is right
Step-by-step explanation:
Given are two graphs. The first one is given as

The second one equation we have to find out.
Option A given as
is having x intercept as
(0,1/2). But our g(x) has x intercept as 1. Hence not correct.
Option B: 
This has x intercept as (0,2). Since does not match with g(x) not correct
OPtion C:

Here x intercept = 1 matches with ours.
Also g(2) = 2, twice as that of original f(x)
Hence option C is not right
Option D is only right because x intercept should be 1 and also when x=4 y=2(log 4 to base 2)
3 2/3 - 1/2
= 11/3 - 1/2
= 22/6 - 3/6
= 19/6
= 3.1666666667
