Answer:
c. No, for each height, there are people of different ages.
Step-by-step explanation:
We say that y is a function of x when there is a relationship between x and y. For example, the distance you run on a single day and your average speed.
However
There is no relationship between age and height. For example, we may both be the same age and have very different heights.
So the correct answer is:
c. No, for each height, there are people of different ages.
Answer: 1 27
2. 54
9 243
10. 270
Step-by-step explanation: for one batch, the total minutes will be 15 + 12, so 27. Multiply 27 times b, the number of batches.
There may be another solution IF he is starting to prepare the next batch while the preceding is in the oven. Since this is not stated, I won't offer that solution here.
Answer:
Step-by-step explanation:
C
2x + 3y = 3
3x - 2y = 11
<span>( 2x + 3y = 3 ) *3</span>
6x + 9y = 9
<span>( 3x - 2y = 11 ) * 2
</span>6x - 4y = 22
subtract those two equations
13y = -13
y = -1
x = 3
