Evaluate the function would be= x^2-f-x
I learned this so many times but I forgot how to do it exactly.
But looking at this, you can already determine that y is equal to -3 so couldn't you use that as an answer.
Answer:
A y = 40x + 75
B 1 hour = 115
2 hour = 155
3 hour = 195
4 hour = 235
5 hour = 275
6 hour = 315
C, D, E look at pic below
plz mark brainliest
The equation would be y= .40x + 3 , The slope would be 2/5 and the y intercept would be 3 , the cost of a 20 minute call would be 11 dollars
