Answer:
• no
• no
• no
• yes
Step-by-step explanation:
Let's start by solving the inequality.
-8 +5w >32
5w> 32 +8
5w> 40
Divide both sides by 5:
w> 8
This means that the value of w should be greater than 8.
Since w is not ≥8, the value of w does not include 8. -6 and -5 are smaller than 8 and are thus not the value of w either.
9, being greater than 8, is a solution to the inequality.
You are right about the domain
it is all real values of x except 4
So about the range we must make x subject of the formular so we know the values of y in which g(x) is defined
u
notice, is an arithmetic sequence, simply adding 6 to get the next term's value.
Answer:
<u>0.035 grams</u>
Step-by-step explanation:
<u>Grams of salt per gram of ocean water</u>
- Divide the amount of salt by amount of water
- 525 g / 15 kg
- 525 g / 15000 g [∴1 kg = 1000 g]
- 0.035 / 1
For every gram of ocean water, there is <u>0.035 grams</u> of salt dissolved in it.
