<h3>
Answer:</h3>
A. y = (-6/5)x +10
<h3>
Step-by-step explanation:</h3>
The given line has a negative slope (downward to the right). The only equation offered with a negative slope is the one of selection A.
_____
<em>Complete working</em>
A parallel line will have the same slope. If there are less-obvious choices to select from, you need to know the slope of the given line. That is computed from ...
... slope = (change in y)/(change in x)
The coordinates of two points are given, so we can find the slope as ...
... slope = (-4-2)/(-1-(-6)) = -6/5
There are a number of ways to write the equation of a line, but in slope-intercept form, the slope is the coefficient of x. You will be looking for a choice that has an x-coefficient of -6/5.
Answer:
m is equal to 36.
Step-by-step explanation:
To get rid of division, all you need to do is multiply both sides of the equation by the denominator, which is 12 in this case:
So m is equal to 36
288 books.
8 books in 5 minutes.
60 minutes in one hour.
5 * 12 = 60
60 minutes * 3 = 3 hours
8 * 12 = 96
96 books in one hour.
96 * 3 = 288
288 books in three hours.
Answer:
the common difference is 5.4 and yes, this is an arithmetic sequence
Step-by-step explanation:
Each new term is derived by adding 5.4 to the previous term:
2.1 + 5.4 = 7.5,
7.5 + 5.4 = 12.9,
and so on,
so the common difference is 5.4 and yes, this is an arithmetic sequence.
