Answer:
Step-by-step explanation:
3(2x + 7) - 2 (x + 5)
need to distibute
5x+10-2x+3
combine like terms
3x+13
divide
x=4.3
(x+2)(4+y)(5+6)(2+x)(4+0.5x)
combine like terms
(x+2) (4+y) (11) (x+2) (4+.5x)
11(x+2)^2 (4+y)(4+.5x)
distribute
11(x^2 +4x+2) (16+4y+2x+.5xy)
(11x^2+44x+22)(16+4y+2x+.5xy)
5.5 x^3 y + 22 x^3 + 66 x^2 y + 264 x^2 + 198 x y + 792 x + 176 y + 704
5/3+2/5=25/15+6/15=31/15=2 1/15
2 1/15 or 31/15
Those points you can see on the graph.
The first one refers to the x value and the second, to y value. If you notice, when you have x = 0, y = 3. When x = -5, y = 0.
When the line intercepts one of the axis, means the other coordinate is = 0.
3 is y intercept, it means the x value of that point is 0. The same happens to the x intercept - 5. It means the y value of that point is 0.
A ( -5 | 0 )
B ( 0 | 3 )
m = Delta y / Delta x.
Delta y is the variation over the x-axis. Delta x, the x axis.
Be safe!
