Third choice is correct hope I helped:3
7:
Parallel lines have the same slope
y = -3x + b
Plug in the x and y values from the point
5 = -3(-4) + b
5 = 12 + b
-7 = b
Answer to 7: y = -3x -7
8:
Perpendicular lines have opposite reciprocal slopes
y = -2x + b
Plug in x and y from the point
-6 = -2(7) + b
-6 = -14 + b
8 = b
Answer to 8: y = -2x + 8
Answer:
a) $14.37 sales tax
b) $25.13 left on gift card
Step-by-step explanation:
Purchases: 78.50 + 32.00 = 110.50
Sales tax: 13%:
1% of 110.50 = 1.1050
1.1050 x 13 = 14.365
rounded to 2 decimal places: $14.37
Total cost: 110.50 + 14.37 = $124.87
Gift card: 150.00 - 124.87 = 25.13
The shape of a bst approaches that of a perfectly balanced binary tree, (log2n) is the time complexity for a balanced binary search tree in case of insertions and search.
In computing, binary bushes are mainly used for looking and sorting as they offer a way to save statistics hierarchically. a few common operations that may be conducted on binary trees encompass insertion, deletion, and traversal.
A binary tree has a special situation that each node could have a most of two youngsters. A binary tree has the benefits of each an ordered array and a linked listing as search is as brief as in a taken care of array and insertion or deletion operation are as fast as in related listing.
In pc science, a binary tree is a tree information shape in which every node has at maximum two youngsters, that are known as the left baby and the proper toddler.

Answer: The correct option is A.
Explanation:
The given equation is,
Multiply both sides by 2.
![2[4(x+5)-5]=\frac{8x+18}{2}](https://tex.z-dn.net/?f=2%5B4%28x%2B5%29-5%5D%3D%5Cfrac%7B8x%2B18%7D%7B2%7D)
Subtract both sides by 8x.
This statement is false for any value of x, therefore the system of equation have no solution and option A is correct.
