Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² - 7x
f(-2) is x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 3(-2)² - 7(-2)
- Exponents: f(-2) = 3(4) - 7(-2)
- Multiply: f(-2) = 12 + 14
- Add: f(-2) = 26
The length is 8. the width is 32.
32(2) = 64
8(2) = 16
64+16 = 80
So the length would be 8 and the width would be 32 since it's 4 times the length.

Answer:
False
Step-by-step explanation:
The given formula is the "explicit" formula for the sequence.
The recursive formula would be ...
a[1] = 160
a[n] = 1/2·a[n-1] . . . . each term expressed in as a function of previous terms
The given statement is false.
Answer:
60 copies
Step-by-step explanation:
first you take 1/6th of the original 90 copies which is 15 and subtract that from the 90, you are left with 75 copies which is how many they had left at the end of yesterday. then you take 1/5th of the 75 copies that are left which is also 15 and you subtract that from 75 and you get 60. that's why at the end of today there are 60 copies left.
Subtract what is to the right of the equal sign form both side of the equation but any way the answer is 0
