The most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.
<h3>What are parentheses?</h3>
In mathematics, parenthesis is used to arrange numbers in the sequence of operations, clarify numbers, and denote multiplication.
Suppose you have an expression as:-
E = { ( 5-2 )8} 6
In this case, you would calculate 5 minus 2 first (parentheses), then multiply by 8 (brackets), then complete the part inside the curly braces, and finally multiply by 6.
Therefore the most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.

Answer:
(0,0)
Step-by-step explanation:
Y = 2x is a <u>proportional</u> relationship because it follows the form y = kx, where k = constant of proportionality. Proportional relationships intersect the y-axis at (0,0), thus having a y-intercept of 0, but we usually don't write the 0.
Given the information above, y = 2x intersects the y-axis at (0,0), the origin.

Answer: The answer is (d) 
Step-by-step explanation: Given equation to be factored is
The given expression is quadratic, so we can factor it into two linear factors, by using the following factorisation rule.
So, the given equation can be factorised using the above rule. The factorisation is as follows.
Thus, the correct option is (d).

Answer:
Step-by-step explanation:
<u>Let the cost of daylilies = d and ivy = i, then we have below equations:</u>
- d + 12i = 114
- 10d + 10i = 150
<u>Simplify the second equation:</u>
<u>Subtract the second equation from the first:</u>
- d - d + 12i - i = 114 - 15
- 11i = 99
- i = 9, ivy costs $9
<u>Now find d:</u>
- d = 15 - 9 = 6, daylilies cost $6
