Answer: 1x + 2y = 4
Step-by-step explanation:
The equation of the line is y = -1/2x + 2.
First, let's make 4 on one side of the equation. First, bring x to the left. y + 1/2x = 2. Then multiply the whole equation by two. Thus, 1x + 2y = 4.

Answer: 182.88 cm
Step-by-step explanation: 1ft = 12 in, so you convert the 6 feet to inches first by multiplying 6 x 12, which equals 72. Then multiply 72 by 2.54, which equals 182.88.
The third choice is appropriate.
an = 5 - 3(n - 1); all integers n ≥ 1
_____
This equation follows the form for the general term of an arithmetic sequence.
an = a1 + d(n - 1)
where a1 is the first term (corresponding to n=1), and d is the common difference. From the problem statement, a1 = 5 and d = 2 - 5 = -3.
Answer: 40.13% of the soda bottles will have a volume less than 32 oz.
First, we need to find the z-score. That is the number of standard deviations below the mean.
(32 - 32.3) / 1.2 = -0.25
A bottle of 32 oz is -0.25 standard deviations below the mean. Use a standard normal distribution probability table and you will find the 40.13% of the scores are below a z-score of -0.25.
