Answer:
The x is the domain and the y is the range. It's still a function
Step-by-step explanation:
Move 50x to the opposite sude so 50x-200>-75
move 200 over so 50x> 125
divide so x>2.5
1 1/2 + 1 1/2 & 1 3/4 + 1 1/4
To write the given phrase as an algebraic expression you can identify what does each part of the phrase mean:
59 less than: You have to substract 59 to the other part of the phrase
twice a number: as the number is n, twice a number is 2n
Then, you get the next algebraic expression:
54 + 46 = 100
180 = Triangle
180 - 100 = 80
80 is the answer.
