2m=-6n-5
Solve for M
Answers
m= -3n -5/2
The equation is in standard form
2m = −6n −5
Divide both sides by 2
2m/2 = -6n-5/2
Dividing by 2 undoes the multiplication by 2
m= -6n -5/ 2
Divide −6n−5 by 2
m= -3n -5/2
Hope this helps :)
m= -3n -5/2
What is mathematical equation?
Equation is defined as the state of being equal and is often shown as a math expression with equal values on either side, or refers to a problem where many things need to be taken into account. An example of an equation is 2+2 = 3+1.
In the given equation,
2m = −6n −5
Divide by 2 on both sides, we get
2m/2 = −6n/2 −5/2
m = -3n - 5/2
Therefore, our value of m is in terms of n, which is -3n - 5/2

You are preparing a case study on the dallas cowboys. You use many methods of data collection in creating the case study. Here is an excerpt: the dallas cowboys were formed in 1960 and have had seven head coaches since then. I surveyed 100 people and one of the questions was, who is your favorite coach of the dallas cowboys? Seventy people said tom landry, fifteen said jimmy johnson, five said bill parcells, and ten answered other. One of those who answered other was my brother. I asked him which coach was his favorite and he said, "barry switzer because he was the last one to win a championship." i knew he was kidding because he had a smirk on his face. The excerpt relays information gathered from questionnaires, interviews, observations, and historical data. Identify the information from the case study that was collected by each of the four methods.

Questionnaire: one of the questions was, who is your favorite coach of the Dallas cowboys?
Interview: I asked him which coach was his favorite
Observation: I knew he was kidding because he had a smirk on his face. This observation showed that Barry Switzer was not really his favorite coach.
Historical data: I asked him which coach was his favorite and he said, "Barry Switzer because he was the last one to win a championship." This historical data shows that the reason why Barry Switzer was chosen as the researcher's favorite coach was that he was the last to win a championship.

Answer:
A. 63
Step-by-step explanation:
Given functions:
f(x) = 2x² + 5
g(x) = 8 + x
find:
g o f(-5)
Solution:
Start first by finding f(-5);
f(x) = 2x² + 5
= 2(-5)² + 5
= 50 + 5
= 55
Now
g o f(-5);
g(55) = 8 + 55 = 63
