Write the equations for the basic absolute value equation y=|x-h|+k under the given transformations:
BlackZzzverrR [31]
<span>Left & Right affect the h,
Up & Down affect the k,
Shrink & Stretch affect the "a" (which is in front of the absolute value expression).

1. shift 1 unit to the right and up 2 units → y = |x-1| + 2
2. </span><span>shift 3 units to the left and 7 units down → y = |x + 7| - 7
3. </span><span>vertical shrink by a factor of 1/3 → y = \frac{1}{3}|x|
4. </span><span>vertical stretch by a factor of 3 → y = </span><span>3 |x|</span>

Please help. i dont understand, so if you could kindly please show me step by step

4.7244m

convert feet to inches using 1 foot = 12 inches

15.5 feet = 15.5 × 12 = 186 inches

multiply this by 2.54 to convert to cm

186 inches = 186 × 2.54 = 472.44 cm

now 1m = 100cm

divide 472.44 by 100 to convert to m

472.44 ÷ 100 =4.7244m

Write the 2-digit number that matches the clues. My number has a tens digit that is 8 more than the ones digit. Zero is not one
laila [671]
Firstly attention should pe paid to the exact words given in the problem and then only the answer can be easily deduced.
It is a 2 digit number and that is said in the problem
Now For the tens digit it has been said that it is 8 more than the ones digit. The ones digit cannot be zero and that is already mentioned in the problem.
So if we take the ones digit to be 1, then the tens digit will be= 8 +1
                                                                                                 = 9
Now if we take the ones digit to be 2, then the tens digit will be = 2 + 8
                                                                                                     = 10
So it cannot be 2 as the tens digit takes the number to a 3 digit number and it is not possible.
So the answer to this problem is 91.
