If lines are paralel, then they have the same slope
if the lines are pependicuilar, the slopes mutiply to -1

so

y=mx+b
m=slope

and
ax+by=c
-a/b is the slope

given
y=2/3x-2
slope is 2/3

x+y=4
slope is -1/1 or -1

2/3≠-1 and -1 times 2/3≠-1 so they are neither perpendicular or paralell

since they aren't paralell, we know they intersect somewhere

Solve each of the following literal equations for c: (c/b) - x = 2d and ac + bd = x
maks197457 [2]
(c/b) - x = 2d
(c/b) = 2d + x
c = b(2d + x)
c = 2db + bx

ac + bd = x
ac = x - bd
c = (x - bd) / a OR c = (x/a) - (bd/a)

Height = = 3.75 in

Volume of rectangular prism = 1,050 inches

Find:

Length of prism

Computation:

Volume of rectangular prism = WHL

1,050 = Length of prism × 16 × 3.75

Val walks 2 3 fifths miles each day. Bill runs 10 miles once every 4 days. In four days, who covers the greater distance?
melisa1 [442]
Val covers greater distance because 2 3/5 x 4 = 10 2/5. Bill only ran 10 miles so Val covered 2/5 more miles than him.
