X = 7
Y = 16
Since we know that the bottom two sides are congruent we can make an equation to solve for that X first [2x + 5 = x + 12] . (since we cannot make an equation with the two congruent sides at the top because there are different variables).
Now that we've solved for X which is 7, we can plug it into the top equation [y - 4 = x + 5] which would simplify to [ y - 4 = 12] which would give us 16 for Y<span />
The clearance price of hat is $17.28
Step-by-step explanation:
Price paid by store = $20
Increment = 60% of price paid
Increment = 
Increment = $12
Increased price = 20+12 = $32
Sale = 10%
Discount amount = 10% of increased price
Discount amount = 
Discount amount = $3.2
Sale price = 32 - 3.2 = $28.8
Clearance sale = 40%
Discount of clearance sale = 40% of sale price
Discount = 
Discount = $11.52
Clearance price = sale price - Discount of clearance sale
Clearance price = 28.8 - 11.52 = $17.28
The clearance price of hat is $17.28

Step-by-step explanation:
i)=
m=2/3
x=-3
y = 5
now
y=mx+c
or, 5 = 2/3× -3 + c
or, 5 = -2+c
c =7
now,
y= mx + c
or, y = 2/3×x+7
or, y = 2x/3+7
or, 3y = 2x+21
so, 3y-2x=21
equation would be 3y-2x=21.
now
ii)=
if slope of 3y-2x=21 and 2x-3y = 0 are same, they are parallel.
2x-3y = 0
2x = 3y
lets suppose x is 9
now
2x=3y
2×9 = 3y
or, 18 = 3y
so, y = 6
one coordinate would be (9,6) now
lets again suppose x is 3
2x=3y
2×3 = 3y
or, 6 = 3y
so, y = 2
another coordinate is (3,2)
now lets find slope
x1=9,y1=6
x2=3,y2=2
slope = (y2-y1)/(x2-x1)
= (2-6)/(3-9)
= -4/-6
= 2/3
Since, slope of 3y-2x=21 and 2x-3y has same slope 2/3, they are parallel.
