Answer:
![[4,0,3,1,2,5]](https://tex.z-dn.net/?f=%5B4%2C0%2C3%2C1%2C2%2C5%5D)
and ![[6,9,8,7]](https://tex.z-dn.net/?f=%5B6%2C9%2C8%2C7%5D)
Step-by-step explanation:
GIVEN: an array of ten integers 
.
TO FIND: If we partition this array using Quick sort's partition function and using 
for the pivot. List the elements of the resulting array after the partition finishes.
SOLUTION:
quick sort is a divide and conquer algorithm in which an array is partitioned into sub-arrays about an pivot element by checking whether elements are greater than pivot or and then sub arrays are sorted recursively.
Here is the pivot element.
two arrays will be created, in first array element less than or equal to pivot element are stored in other elements greater than pivot element are stored.
Starting from first element of array
elements in first array will be ![=[4,0,3,1,2,5]](https://tex.z-dn.net/?f=%3D%5B4%2C0%2C3%2C1%2C2%2C5%5D)
elements in second array will be ![=[6,9,8,7]](https://tex.z-dn.net/?f=%3D%5B6%2C9%2C8%2C7%5D)
Hence the resulting array after the partition finishes are and
Answer: 46 puzzles
Step-by-step explanation:
There are 70 puzzles in total in the book.
Jackie has completed / of those puzzles. In whole numbers that is:
= 2 /5 * 70
= 28 puzzles
She then completes 18 more puzzles.
Total that she has completed is:
= 28 + 18
= 46 puzzles
Simplify each term<span>.
</span><span>10x−20−11=4+3x
</span>Add <span>−20</span><span> and </span><span>−11</span><span> to get </span><span><span>−31</span>.
</span><span>10x−31=4+3x
</span>Move 3x to the left-hand side of the equation<span> by subtracting </span><span>3x</span><span> from both sides.
</span><span>10x−31−3x=4
</span>Add <span>10x</span><span> and </span><span>−3x</span><span> to get </span><span><span>7x</span>.
</span><span>7x−31=4
</span>Since <span>−31</span><span> does not contain the </span>variable<span> to solve for, move it to the right-hand side of the </span>equation<span> by adding </span>31<span> to both sides.
</span><span>7x=31+4
</span>Add 31<span> and </span>4<span> to get </span><span>35.
</span><span>7x=35
</span>Divide<span> each </span>term<span> in the </span>equation<span> by </span><span>7.

Answer:
-4.5
Step-by-step explanation:
I added 3.25 and .5=3.75. Then i did 0.25*-6=1.5. -1.5+3.75=2.25. 2.25*2=-4.5
1/2 is the slope. You can tell because if you count the rise of one point from the next is one and the run is two.
