Plug in 8 for g(8) to get 8(2) + 1 which is equal to 17, plug in 7 for f(x) to get 10-7 which is equal to 3. 17 + 3 is equal to 20 which means g(8) + f(7)= 20
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences

Step-by-step explanation:
So when you subtract by a negative number, it is the same thing as adding the two numbers.
First find a the LCD, or the least common denominator.
LCM(7,6) = 7•6 = 42
Then make the fractions have 42 as a denominator.
7 5/6 • 7/7 = 7 35/42
4 1/7 • 6/6 = 4 6/42
Finally, add the two mixed numbers
7 35/42
+4 6/42
11 41/42
So 11 41/42 is your answer
By using the calculator, log 6 = 0.7781...
log 60,000 is just equal to log (6 * 10,000)
log (6 * 10,000) = log 6 + log 10,000
As we know that log 10 = 1, log 100 = 2, log 1000 = 3, and so on.
So log 10,000 = 4
Going back to our equation,
log (6 * 10,000) = log 6 + log 10,000
log 60,000 = 0.7781 + 4
So log 60,000 = 4.7781
