-3y = -2x -6
Y= 2/3x + 2
When x= 3
Y= 2/3(3) + 2
Y= 2+2 = 4
(3,4)
When x= 6
Y=2/3(6)+2
Y= 4+2 = 6
(6,6)
When x= 12
Y= 2/3(12) + 2
Y= 8+2=10
(12,10)
Rectangles and squares are usually considered to be special cases of isosceles trapezoids though some sources would exclude them.

Answer:
14.42
Step-by-step explanation:
The three lengths are 3x, 6x, 8x.
The perimeter of a triangle is the sum of all lengths:
3x + 6x + 8x = 520.
Solving for x,
17x = 520
x = 30.59 cm
So the three lengths are
3(30.59) = 91.77 cm
6(30.59) = 183.54 cm
8(30.59) = 244.72 cm
Answer:
C) 8.5%
Step-by-step explanation:
First, subtract the cost after tax to the cost before tax.
84.63 - 78.00 =
6.63
Then, divide the original cost from this
6.63 / 78.00 =
0.085
When reading percentages on a calculator, we know this is equivalent to 8.5%
Hope this helps! :)
