Answer:
Step-by-step explanation:
If we are given a function <em>f</em> and we want to shift it <em>a</em> units horizontally, the resulting function will be f(<em>x</em> - <em>a</em>), where a positive <em>a</em> is a shift rightwards and a negative <em>a</em> is a shift leftwards.
We have the function:
And we want to shift it two units to the left.
Since we want to shift it two units to the left, <em>a</em> = -2. Therefore, our new function, let's call it <em>g</em>, must be f(<em>x</em> - (-2)) or f(<em>x</em> + 2). Substitute:
Simplify. Expand:
Combine like terms. Hence:
First subtract 24 from 45 to get 21. Then add 7 to 21 to get 28.
1. He owes you 23 dollars and his change will be 7 dollars.
2, She owes you $6.50 and her change is $3.50 .
Answer:

Step-by-step explanation:
B-4.2< -7.5
Explanation-
