Step-by-step explanation:
dilatation with scale factor (k) = 2
Answer:
C and F
Step-by-step explanation:
Given
(3x - 5)² = 19 ( take the square root of both sides )
3x - 5 = ± 
← note plus or minus
Add 5 to both sides
3x = ± + 5 ( divide both sides by 3 )
x = ±
Separating the solutions
x = 
→ C
x = 
→ F
-3x-1 = 2-(-3)
-3x-1 = 2+3
-3x-1 = 5
-3x = 5+1
-3x = 6
x = 6/(-3)
x = -2
1) Before tax = $249.99
100% = 1 = 249.99
4% = 0.04
100% + 4% = 104% = 1.04 multiplier
1.04 x $249.99 = $259.9896 = $259.99 After Tax
2) After tax = $249.99
100% = 1
4% = 0.04
1 + 0.04 = 1.04
104% = $249.99
$249.99 / 1.04 = $240.375 = $240.38 Before Tax
