Step-by-step explanation:
CD = 6 cm because opposite sides are equal
angle d = 110

STEP-BY-STEP SOLUTION:
Let original price = x
( 100% - 20% )x = $44
0.8x = 44
x = ( 44 / 80 ) × 100%
x = $55
Okay, so you are asking how they came up with 0.8 as shown in the 2nd line above which I will rewrite below:
0.8x = 44
The 0.8 refers to how much of x ( original price ) is left in the new price.
So, if:
x = 100%
Then:
New price = x - 20% = 100% - 20% = 80%
Now, to get 0.8 is as follows:
80% = 0.8
Answer:
2/3x - 3 = 5
Step-by-step explanation:
Let x be the number
2/3x - 3 = 5
Add 3 to each side
2/3x-3+3 = 5+3
2/3x = 8
Multiply each side by 3/2
3/2*2/3x = 8*3/2
x = 12
A function is odd if:
f ( - x ) = - f ( x )
A ) f ( - x )= 0.8 ( - x ) ^3 = - 0.8 x^3 = - f ( x )
Answer: A ) f ( x ) = 0.8 x^3 is an odd function.
Functions B ) and C ) are even and D) is neither even nor odd.
