4400 - 3600 = 800
Decrease = 800 Calories
Original value was 4400 Calories.
Now,

After Rounding off,
Decrease percentage will be 18 %
Add the two values being multiplied by m
37.26 + 2.7 = 39.96
39.96 m + 0.0015 is the most simplified you can get without having a way of finding the value of m. I apologize if I am mistaken, but I'm fairly certain! :)
Answer:
x is equal to negative one, and y is equal to negative four.
Step-by-step explanation:
You can do this by solving one of the equations by either x or y, then substituting it into the other. Let's solve the second one for y:

Now we'll substitute that into the first equation:

So we now know that x is equal to -1. We can simply substitute that into one of the original equations to find y:

We now know that x is equal to -1, and y is equal to -4. We can also check our answer by plugging that -4 into the other equation, and see if we still get -1:

So we know that our answer is correct.
The slope in the equation of a line is the coeffient of x
the equation of a line and a point is
(y-y1)=m(x-x1)
where m is the slope so 3 is the slope
