Find the area bounded by the equations y=15-3x and y/3+4=2x and the x-axis

[From: ] [author: ] [Date: 12-08-27] [Hit: ]
and then work out what those lines are. Then I presume whatever area is made using those lines is what youre after.......
I have no idea what "Find the area bounded by the equations" means
I got x to be -17.5 and y to be 67.5 ..
Please help.
answer was said to be 9....

what?

We have to integrate, or you could possibly graph it and then find area of trapezoid or whatever shape we get.

y = -3x + 15
y = 14x
14x = -3x + 15
17x = 15
x = 15/17

∫ (-3x + 15) - 14x dx

∫ -17x + 15

(-17/2)x^2 + 15x

From 0 to 15/17

(-17/2)(15/17)^2 + 15(15/17)
(-1/2)(225/17) + 225/17
-225 / 34 + 450/34
225/34

Not 9, but i think its because you typed in your second equaiton wrong

Well I'm assuming you would draw a graph, and then work out what those lines are. Then I presume whatever area is made using those lines is what you're after.
