Answer:
The average rate of change of f(x) from 2-3 is 0.176
Step-by-step explanation:
Rate of change= change in y / change in x
= log 3 - log 2 / 3-2
= 0.477-0.301 / 1
= 0.176
Answer:
(8, 5) (Answer C)
Step-by-step explanation:
Write this system of linear equations in a (vertical) column:
4x - 3y = 17
5x + 4y = 60
Let's eliminate y through addition/subtraction:
Multiply 4x - 3y = 17 by 4, obtaining 16x - 12y = 68, and
multiply 5x + 4y = 60 by 3, obtaining 15x + 12y = 180. Then we have:
16x - 12y = 68
15x + 12y = 180
----------------------
31x = 248, and so x = 248/31 = 8.
Now find y. Substitute 8 for x in 5x + 4y = 60: 5(8) + 4y = 60, or
4y = 60 - 40 = 20.
Thus, y = 20/4, or y = 5.
The solution is (8, 5) (Answer C)

Answer:
$219.99
Step-by-step explanation:
To find the price without the sale tax you find the opposite of 12%, which would be 88%. Then you multiply .88 by 249.99 to get 219.9912, and since it is money you round to the hundreth to get 219.99.
