PEMDAS comes first. Instead of adding 9+2 first, they should've multiplied 2x3. The final answer would be 15.
Answer:
Step-by-step explanation:
a) 8.23 x 10^5 move the decimal over 5 places, 319000000 is 319 million move the decimal over until there is one number on the left side --> 3.19 x 10^8
b) 3.19 x 10^8 / 8.23 x 10^5 = 387.61 roughly 388 times larger
24-3x=-27
-24 -24

Answer:
D. An input is the value that determines another based on the relation or function rule, usually the x-values in a set of ordered pairs on a tale or graph.
Step-by-step explanation:
For any relation (given ordered pairs), there are x - values and y-values, also called inputs and outputs. For every input, there is an output. For example, given the function rule:
y = 2x + 1
If x = 1, y = 3
If x = 2, y = 5
and, so on..
So, the output (y) is determined by the input (x) and is usually the x-values.
4,000,000 would be your answer
