The graph of the line with equation y = 7 x + 8 crosses the x-axis when x = ?

X=8 because when you put it into the graphing calculator thats when they intersect

To find the X intercept plug in a zero for the Y then solve for X.
y = 7x + 8
0 = 7x +8
Subtract 8 from both sides
-8 = 7x
Divide both sides by 7
-8/7 =x

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
