first you convert to slope intercept form
3x+y = 5 is the same as y = -3x+5
x - 4y = 32 is the same as y = 4x-8
then you graph
(starting with the y-intercepts as your first points)
the point where the two lines intercept is your solution.
Answer: Work done by both of them in k hours is
Explanation:
Since we have given that
Number of hours Mr. I does a job = x hours
Number of hours Mr. L does a job = y hours
Work done by Mr. I is given by
Work done by Mr. L is given by
Work done if they do together is given by
Work done if they work together for k hours is given by
Hence, work done by both of them in k hours is
If U = {a, b, c, d, e, f, g, h}, A= {a, b, c, d, e) and B= {c, d, e, f, g), find A-B and A nB.

<em>here</em><em>,</em>
U = {a, b, c, d, e, f, g, h}, A= {a, b, c, d, e) and B= {c, d, e, f, g),
now,
A-B = {a,b}
A n B = { c,d,e}
Hello!
To find the area of a rectangular prism you do 2(lw + lh + wh)
Put in the values
2(9 * 2 + 9 * 6 + 2 * 6)
2(18 + 54 + 12)
2(84)
2 * 84 = 168
The answer is 168 cubic inches
Hope this helps!
Yes- though we may say "When will we ever use this?" ever so often in class, the reality is that we use mathematics in everyday life. From simple addition, to factoring, to finding the angles of various components to a building, math is always being used in real life.
