To convert a mixed number into<span> a </span>fraction:First, <span>multiply the </span>whole number<span> by the denominator (the bottom part), and add the result to the numerator (the top part). That's how you convert a mixed number into a fraction I hope that helped. Also if you are in college don't you think you should know that? LOL :D Glad to help.</span>
Solve first for the solution of the inequalities. This can be done by replacing first the inequalities sign with the equal sign.
x + y = 1
2y = x - 4
The values of x and y from the system of linear equation are 2 and -1. This means that the intersection of the lines should be at point (2, -1).
Substitute 3 to x and determine the value of y from the second inequality.
2y ≥ x - 4
Substituting,
2y ≥ 3 - 4, y ≥ -1/2
Hence, the solution to this item should be the fourth one.
You can use either of these, depending on your teacher.
2.e+14
2.0*10^14
Y=-x
(X,Y) will change to -> (-y,-x)
(5,-3) will change to ->(3,-5)
-3 changed to 3 because -(-3) = 3
So the answer is (3,-5). I recently learn about this one too.
