For this case we have the following functions:

Equalizing we have:

To solve we factorize, that is, we look for two numbers that when multiplied give a result of 4 and when added together give a result of -4. These numbers are -2 and -2.

Thus, we have:

So, the solution is
Answer:

Answer: (a,b)= (7.13 ,-8.27)
Step-by-step explanation:
From the data, we have
A-B+3C=0
where, A= (-8.6, 18.0)
B= (12.8, -6.8)
and let C= (a, b)
So, putting values
(-8.6, 18.0) - (12.8, -6.8) + 3(a,b)=0
3(a,b) + (-21.4, 24.8) = 0
3(a,b)= (21.4, -24.8)
(a,b)= (7.13 ,-8.27)
Answer:
4
Step-by-step explanation:
This can be solved by multiplying 26.2 by 1/10 to get 2.62
You can also just move the decimal one to the left to get he same answer of 2.62
