I think it would best be displayed as a line plot.
Answer:
x = -1 and y = 1
Step-by-step explanation:
5x + 2y = -3 . . . . . . . (i)
x + 5y = 4 . . . . . . . (ii)
- Finding x in terms of y from eq. (ii) :-
x + 5y = 4
x = 4 - 5y
- Placing this value of x in eq. (i) :-
5(4 - 5y) + 2y = -3
20 - 25y + 2y = -3
-23y = - 23
<u>y = 1</u>
- Placing the value of y in eq. (i)
5x + 2(1) = -3
5x + 2 = -3
5x = - 5
<u>x = -1</u>
From the slope our equation so far is
y = -4/5x + B
Now we find B
-------------------------
To find be all we have to is substitute (-5,-4) for x and y in <span>3x + 5y = 15
</span>(-4) - (-4/5)( -5) = b
-8 = b
---------------------------------
So your equation would be y = -4/5x - 8
Surface area is 8.25(pi) or 25.9181
Volume is 3(pi) or 9.427
