Answer:
Solve the equation so it is in the y=mx+b form.
Step 1. 6x+9y = 216
Step 2. 9y = -6x+216
Step 3. y = -6/9x+24
Step 4. Simplify/Reduce to get y = -2/3x+24
Since it is Parallel then the slope is the same so the slope is -2/3x.
Step-by-step explanation:
14x + 70 + 20x + 8 = 180
34x + 78 = 180
34x = 102
x = 3
ABX = 14(3) + 70 = 112
CBX = 180 - 112 = 68
Answer:
see explanation
Step-by-step explanation:
Since the pentagon has one line of symmetry. This will be a vertical line through C, thus
CD = BC = x + 1 and ED = AB = 2x + 3
Perimeter = AE + ED + DC + CB + BA
= 4x + 2x + 3 + x + 1 + x + 1 + 2x + 3 = 10x + 8
Perimeter is given as 21, thus
(b)
10x + 8 = 21 (subtract 8 from both sides )
10x = 13 ( divide both sides by 10 )
x = 
= 1.3
Cost of TV = $1000
Sales Tax = 8% x $1000
Sales Tax= 0.08 x $1000 | Rewrite 8% as decimal
Sales Tax = $80
Price after tax = $1000 + $80 | Add cost of TV and tax
Price after tax = $1080
