Answer:
x - 9 = 12
Step-by-step explanation:
We can use x as "a number"
So the equation so far is just "a number", or x.
Decreased by 9 can also be said as subtracted by 9, so that makes the equation x - 9.
"is 12" can also be said as equals 12, which makes the equation x - 9 = 12
Answer:
Option (2)
Step-by-step explanation:
Given functions are,
c(x) = 
d(x) = x + 3
Equation of the composite function will be,
(cd)(x) = c(x) × d(x)
= 
= 
This function is defined only when denominator is not equal to zero.
(x - 2) ≠ 2
Therefore, for real numbers except x = 2 will be the domain of the composite function.
Option (2) will be the answer.

Answer: A. 397 miles
Step-by-step explanation:
Add the miles traveled on Saturday and Sunday to find out how many miles were traveled in total.
409 + 239 = 648
Now, subtract the total number of miles traveled from the original distance.
1,045 - 648 = 397
8 would be the constant but in this situation there is a variable next to it so I’m not sure if it would be considered a constant
