Answer:
n=18
Step-by-step explanation:
100=4(n+7)
100=4n+28
-28 -28
72=4n
n=18
In case this wasn't easy to understand, first you distribute the 4 to the n and 7, to get 28, after that the equation becomes 100=4n+28, then you subtract 28 from 100, and from itself to get the 4n by itself, you are left with 72=4n, after that you just divide 4n and 72 by 4 and get n=18
hope that helped :)
You can't factor out c or d since we don't know what they are so you have to find an integer. both are divisible by 5, which would become 5(9c+2d). 9 and 2 don't have anything in common so that is it.
45c+10d = 5(9c+2d)

The correct answer i believe is C
Your answer is y = -3x + 1
To find the equation of the line we need both the slope and where it intercepts the y-axis. We are given where it intercepts the y-axis because they tell us it goes through the point (0, 1) and this is a point where x = 0, so it must be on the y-axis.
The equation for finding the slope of a line given two points is where and are points on the line. Using this, we can substitute in the points we're given and get:
(-5 - 1)/(2 - 0) = -6/2 = -3
Therefore our slope is -3 and our intercept is 1, so the final answer is y = -3x + 1
I hope this helps!
