Answer:
d
Step-by-step explanation:
3 shirts that each costs s dollars would be 3s
jeans is $30, pair of shoes is $50, add $30+$50 and you'll end up with $80
so, an expression in the simplest form that represents the total cost would be:
d. 3s+80
They are perpendicular lines. they form right angles
Y=mx+b
m=slope
b=yint
y=16500-1500x
y=-1500x+16500
slope is -1500
yintercept is 16500
Answer:
$20.70
Step-by-step explanation:
$9.20 x 2 1/4 (lbs) = $20.70
Answer: x=4, y=-2
Step-by-step explanation: 4x+y=14, x-2y=8
4x+y-y=14-y
4x/4=14/4-y/4
x=14-y/4-(2y)(4)/4
4(14-9y)/4=(8)(4)
14-9y-14=32-14
-9y/-9=18/-9
y=-2
(14)-(-2)/4
14+2/4
16/4
4
x=4
x=4, y=-2
