1. Always true. 1+1=2
2. Always true. 1+e is irrational.
3. Sometimes true. e + (-e) = 0 which is rational.
4. Always true. 1*1 = 1
5. Sometimes true. 0*e = 0 which is rational.
6. Sometimes true. Sqrt(2) * sqrt(2) = 2 which is rational.
The question asked for an example to support your answer, but none of the answers can be proven with just one example. The answers which are sometimes true need 2 examples to be proven, and the answers which are always true cannot be proven by example.
For #3, you just have to plug in the numbers for x.
It tells you what to substitute for x in the question. (x = 0, 1, 2, 3, 4, 5, and 6)
For example, let's substitute 0 for x.
6x - x² (the 2 means square the number, or multiply it by itself)
6(0) - (0)²
0 - 0
= 0.
You'll do that to all the numbers (1-6) and fill out the table.
For #4, you have to solve using the distributive property to find out if the equations on both sides are equal.
I'll do the first one for you.
6a - 8 = 2 (3a - 5)
6a - 8 = 6a - 10
They're not equal.
Answer:
See the attachment. (All results are integers, so are correct to 6 decimal places.)
Step-by-step explanation:
The function simplifies to ...
... f(x) = x(x-9)/((x+1)(x-9))
... f(x) = x/(x+1) . . . for x ≠ 9
There are 16 ounces in a pound so all you have to do is multiply 16 and 3.
16*3=48
ANSWER= 48 ounces
