How many integers n leave remainder 4 when divided by 7, if n satisfies the given inequality?
1 answer:
Consider inequality This inequality is equivalent to inequality
This means that
The greatest integer number n, such that when dividing by 7 gives the remainder 4 is 39. Then subtract 7, you get 32, then 25 and so on.
When n=-39, -32, -25, -18, -11, -4, 4, 11, 18, 25, 32, 39 then dividing by 7 the remainder is 4.
Answer: 12 integers.

Step-by-step explanation:
Given: Emelina wrote the equation of a line in point-slope form as shown below.
To write the equation in intercept form, first we multiply 3 inside the bracket values in the right side , we get
Now, subtract 4 from both sides , we get
Hence, Emelina’s equation in slope-intercept form :
