y = | x -5| + |x+5|
as range of x is
-5 < x < 5
we can see if we put x = 0 we get
y = 10
we put any value of x in given range first term is always negative without absolute. and 2nd term is always positive
so
y = | x -5| + |x+5|
= -( x-5) + x + 5
= - x + 5 + x + 5
= 10
so
y = 10 where -5 < x < 5

Answer:
$7
Step-by-step explanation:
P(.80)=5.60
We need to find dot products of 2 vectors:
u·v = x1*x2 + y1*y2
u·v = 2*(-6) + 3*4 = -12 + 12 = 0
Another way to write dot product u·v = |u|*|v|*cos α.
Because the do product = 0, we can write
|u|*|v|*cos α = 0.
That means cos α = 0, and thus α=90⁰, so vectors v and u are orthogonal.
