C(2,-6)
EXPLANATION
The solution set to given inequality is the shaded region.
The points are also located in the graph above.
The only point that falls in the solution region is C(2,-6)
The ordered pair that is in the solution set is C(2,-6)
The third option is correct.
Answers:
- 7: 20 miles
- 8: 28 miles
- 9: 1 error
- 10: Their speed is 50
- 11: 365 words in 5 mins
Step-by-step explanation:
- #7 and #8
Our equation is: With f meaning "fare" (price) and m meaning "miles".
Question 7 - Juan's fare for his ride costs $6.05. We must solve for .
Step 1. Substitute - <em>Substitute the fare for in the equation.</em>
Step 2. Simplify/Solve - Solve for .
<em>- Distribute</em>
<em>- Subtract 0.2 from 2.25</em>
<em>- Subtract -2.05 from 6.05</em>
<em>- Divide both sides by 0.2</em>
<u>And you have your answer of 20 miles.</u>
Question 8 - Same equation, different fare.
Step 1. Substitute
Step 2. Solve
And like so, we have
- Questions 9 - 11
<em>The equation given is . S = typing speed, w = words per 5 mins, and e= errors.</em>
Question 9 -
<em>We are given this information: S = 55, W = 285. We are solving for e</em>.
Substitute -
Solve -
So they would make 1 error.
Question 10 -
<em>Information given: 300 = w, 5=e. We are solving for S</em>
Substitute -
Solve -
Their speed is 50.
Question 11 -
<em>Information given: S = 65, e = 4. We are solving for w.</em>
Substitute -
Solve -
So w = 365.
