Answer:

Step-by-step explanation:
Translating a function up is very simple, all you need to do here is add 8.
If you want to think of it logically,

the whole right side of the function here can be our output. If x is 8, then the output, or height, is also 8. if you wanted to translate that up to 10, you'd simply need to add 2 to it, meaning
. Then, at any given point on the function, it'd be 2 higher than it would be otherwise.
Answer:
y = 27.1
Step-by-step explanation:
We have the value of x:
x = 12
and we need to find the value of y in the expression:
y = x + 15.1
as we can see by the equation, the value of y depends on the value of x.
thus, we substitute x = 12 on the previous equation:
y = 12 + 15.1
y = 27.1
the value of y is 27.1
Answer:
30
Step-by-step explanation:
45-15
So,
Here we have the following algebraic expression:

The first term of this expression is -5x.
This term is clearly a variable term. The variable is x and its coefficient is -5.
