To write this equation in simplest form, we simply need to combine all like terms. The like terms in this particular expression are the terms with an n-variable and the terms with no variable. So we can combine them to simplify our expression.
5n - 6 + n - 1
First step, we can reorder our terms so that like terms are near each other
5n + n - 6 - 1
Now we can combine easily
(5n + n) - (6 - 1)
6n - 5
And that is your simplified expression.
5n - 6 + n - 1 in simplest form is 6n - 5.
Hope that helped! =)
Answer:
a) 675 000
b) 685 000
Step-by-step explanation:
The population of a town is 680 000 correct to the nearest 10 000.
a) To find it lower bound, we level of accuracy by 2 and then subtract from 680 000
The lower bound is:
680 000-5000=675,000
Therefore the least possible population of the town is 675 000
b) We repeat the same process to find the upper bound
680 000+5000=685,000
Answer: 3km 42n

Answer:
94
Step-by-step explanation:
the general formula for the nth term of this arithmetic sequence is
a(n) = 12 + 2(n-1).
The 42nd term would then be a(42) = 12+ 2(42 - 1) = 12 + 82 = 94
Answer:
y = 7x - 6
Step-by-step explanation:
We are given the slope of 7 and the y-intercept of (0, -6).
We can easily write this in slope-intercept form.
m - slope
b - y-intercept
Replace 'm' with '7' and 'b' with '-6'.
Hope this helps.
