The x intercept is the x value when y is 0.
So,
0 = 2/5x + 5
-5 = 2/5x
-25 = 2x
The x intercept is -25/2.
This is a <em>right triangle</em>
I hope this helps!!
Just add all of the same variables. x+1/2x+4x all have the same variable, and 4 is it's own variable. Answer simplified is 5.5x+4.
Distribute it, a(b+c) = ab+ac
=(-2-c)(-1)
= (-2)(-1)+(-c)(-1)
= 2+c
