Answer:
There intersecting lines
Step-by-step explanation:
5x+2y=-8
-5x -5x
2y=-8 -5x
/2 /2 /2
y=-4 -5/2x also
y=-5/2x - 4
&
y=5/2x - 19
neither parallel (slope is not the same)
or perpendicular (slope is not reciprocal or opposite signed)
hope i helped
X= -5 because you divide -5x by -5 to get x alone so you have to 25/-5 which is -5
first speed --- x mph
return speed -- x+16 mph
6/x + 6/(x+16) = 1
times each term by x(x+16)
6(x+16) + 6x = x(x+16)
x^2 + 4x - 96 = 0
(x-8)(x+12) = 0
x = 8 or x is a negative
her first speed was 8 mph
her return speed was 24 mph
check:
6/8 + 6/24 = 1 , that's good!

Step-by-step explanation:
the sum of the lengths of any two sides of a triangle is greater than the length of the third side.
if the sides are a, b, c , then the following must be true
