3(2x + 4) = -6
6x + 12 = -6
6x = -6 - 12
6x = - 18
x = -18/6
x = -3
A.
Explanation: The bigger the negative number, the lower the number actually is.
Answer:
1 day: 4480
2 days: 8960
3 days: 13440
---- function inverse
Step-by-step explanation:
Given

Solving (a): The amount present after 1 day.
Here, 
So:

Solving (b): The amount present after 2 days.
Here, 
So:

Solving (c): The amount present after 3 days.
Here, 
So:

Solving (d): The inverse function of:

Replace f(x) with y

Swap x and y

Rewrite as:

Divide by 4

Take square roots

Replace y with function inverse

The answer is d because you just need to multiply AB by 4
4.5 * (8-) + 36 = 102 - 2.5 * 27
4.5 * 8 - 36 = 102 - 2.5 * 27
36 - 36 = 102 - 2.5 * 27
36 - 36 = 102 - 67.5
36 - 36 = 34.5
Since we know 36 - 36 doesn't equal 34.5 its not true so there is
