Answer:
y = -2/3x + 1
Step-by-step explanation:
Put -2/3x + 1 into y= on the graphing calculator and the point (6,-3) is in the table.
Answer:
174 rpm
Step-by-step explanation:
The question says that the speed is inversely proportional to the length. Thus, Inverse means, as the diameter increases, the speed reduces, or as the diameter reduces, the speed increases.
Thus, from the question, if diameter A is 20, and B is 10, then definitely, the speed will increase from 348 to a higher rate. Mathematically, we have
20 / 10 = 348 / x, where x is the missing speed.
2 = 348 / x
x = 348 / 2
x = 174 rpm
Therefore, the pulley A must have been running at a speed of 174 rpm
To solve this, you need to use cross multiplication. The first fraction, is 3/4 and the second is 6/x, with x meaning how much the container can hold. Multiply 3x(x) and 4x6 equating to 3x=24. From here, use algebra to solve for x, by dividing both sides by three.
Your final answer will be B) 8 qts
Answer:
A line of best fit (or "trend" line) is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points.
Step-by-step explanation:
Answer:
if you have -3×-4=12
Step-by-step explanation:
the reason is that anytime you multiply numbers with negative signs you get a positive value.
In order for you to get a positive number, both numbers you are multiplying must be negative.
But if one of the numbers you are multiplying is a negative and the other number positive then you have a negative value as your answer.
e.g. 3×-4=-12.
