<u>Step 2: Substitute y into the second equation</u>




Answer: 
Answer:
The first one
Step-by-step explanation:
The amplitude is usually the first number (for example, in this equation, the 3). Then you also know that the right or left shift depends on the addition or subtraction sign. Usually, the subtraction sign means to the right and the addition sign means to the left.
37.5*0.010=.375 (or press % button on calculator)
80*.375=30

Answer:

Step-by-step explanation:
The ratio is simply the division of one by another (and simplification).
Hence, <u>the ratio of production of the first line to the second line</u> is 1250 divided by 2825. So,
Ratio =
