Answer:

x + y = 9

5x + 2y = 30

Step-by-step explanation:

We're trying to find the number of sandwiches and bottles of water he buys and we know he bought 9 in total. This can be represented by x + y = 9 (since x represents the sandwiches and y represents the water). Knowing this, we know that sandwiches (x) cost 5 dollars and water (y) costs 2 dollars. We know he spent a total of 30 dollars. The second equation can therefore be represented by 5x + 2y = 30.

A line contains the points (8, 9) and (–12, –7). Using point-slope form, write the equation of the line that is parallel to the
kozerog [31]
For the answer to the question above,
The slope of the line of the line is calculated through the equation,
m = (y2 - y1) / (x2 - x1) 

Using the first two points in the given,
 m = (-7 - 9) / (-12 - 8) = 4/5

The line parallel to this has also a slope of 4/5. Through the point-slope form, the equation of the second line is,
 y - -15 = (4/5)(x - -5)

Simplifying gives the answer of,
y = (4/5)x -11

Eliminating the fraction, 
5y = 4x - 55

I hope my answer helped you.
