The expression would be: x+8
The equation would be: x+8=
The rate of change for function A is 2. It would originally be 2 over one but you can just simplify it down to 2. The rate of change for function B is 3. Which would also originally be 3 over 1.
Answer:
The original number was 54.5.
Step-by-step explanation:
If a number is increased by 2.8%, then it is 102.8% of it's original number.
In mathematics, "of" in virtually all cases means "multiplied by".
Therefore, we do the opposite:
1. Convert to a decimal.
102.8% = 1.028
2. Divide by the decimal.

3. Round it to the nearest tenth.
54.47 rounds to 54.5.
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2).
Answer:No
Step-by-step explanation: 4.4 - 0.33 = 4.07 so there is no reasoning for it to be 1.1 since it make no sense at all.
