Answer: y = 4x + 20
Step-by-step explanation:
4x - y = -20
=> -y = -4x - 20
=> y = 4x + 20
is there anything else to the doc because there isn't anything else attatched....i dont know....pls mark brainliest and ill give you another answer afterwards
btw it would make my day :)
He spends $750, and makes $3000
3000/650=0.22
The answer is 22%
As the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1
As per the question statement, we are given a new mathematical operation a△b=a^2-b/b-a^2 and we are supposed to find the value of 4△3 using the same operation.
Given, a△b=a^2-b/b-a^2
now 4△3 = (4^2-3) / (3-4^2)
4△3 = (16-3) / (3-16)
4△3 = 13 / -13
4△3 = -1
Hence, as the new mathematical operation is defined by a△b=a^2-b/b-a^2, the value of 4△3 using the same operation will be 4△3 = -1.
- Mathematical operation: An operator in mathematics is often a mapping or function that transforms components of one space into elements of another.
