7m + 2 = 6n - 5 Write a formula for f(m) in terms of m.

vlada-n [284]

Answer: m = 6/7n-1

Step-by-step explanation: to get 7m alone dirst we must subtract 2 from both sides so 2-2 = 0 and -5 - 2= -7 so 7m= 6n-7 and divide both sides by 7 to get m alone so 6n divided by 7 = 6/7n and -7 divided by 7 equals -1 so we're left with m= 6/7n-1

Look at the table to answer the question.

Alexus [3.1K]

Answer:

Your power function is y=-2 $x^{2}$

Step-by-step explanation:

The way I found it was.

0=0, so, the function multiply by zero, and have no other term to add

A number (one in a case) gives as a result: -2. So, one, elevated to ANY power results in one, every time. So, I have 1, as a factor and -2 as a result. One is as well a factor that delivers a result equal to the other factor. (3)(1)=3 , (8987)(1)=8987. So, the other factor must be -2

Then I checked all the table, and the results were consistent.
