A but see below.

Step-by-step explanation:

A is likely the best answer, although B is also correct. However you should write things in the other they are given.

n + 7 is the very best way to answer.

7 + n is not wrong but maybe not wanted.

How the bloody hell do i answer these? explain how you did it.1. in the xy plane, line m passes through the points (a,0) and (0,2a), where a 1. what is the slope of line m? a)-2 b)-1/2 c)2 d)-2a e)2a2. first, 3 is subtracted from x and the square root of the difference is taken. then, 5 is added to the result, giving a final result of 9. what is the value of x? a)3 b)4 c)5 d)16 e)193. if s is the set of positive that are multiples of 7, and if t is the set of positive integers that are multiples of 13, how many integers are in the intersection

Step-by-step answer

1. the formula for the slope is
$\frac{y2 - y1}{x2 - x1}$
where (a,0) is x1, y1 and (0,2a) is x2, y2. try to see if you can do it now (:

2. take a number x, then step by step do whatever the question asks for example "First, 3 is subtracted from x" so you know the first thing you need to do is x-3, then go on and you'll get an equation which you can use to solve for x, try it!

3. make a set, S, which has multiples of 7. then make a set, T, which has multiples of 13.
now the intersection of S and T is a set having all elements of S, also found in T (basically the numbers that are common to both). try doing it now!

for fourth, this requires a profit formula(that I do not know), must be explained in your book, try going over it, I'm sure you'll find it there!

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5
