9x- 7i > 3 (3x-7u)
9x- 7i > 9x-21u
9x-9x-7i>21u
-7i > 21u
Answer:
Yes. They have enough to pay their bill: 21 dollars times 1.06 = 22 dollars and 26 cents and 22 dollars and 26 cents times 1.15 = 25 dollars and 60 cents.
Answer:3 4 -7 1
Step-by-step explanation: {note and bc I'm kind of smart!}
Answer: y= -3x
(there is no y-intercept in the points you listed so if you can find one on a picture of your question, do so. but since i do not see a given y-intercept, i assume it is 0)
To find the slope, use the two points given.
1st: subtract the y-values. 0-6= -6.
2nd: subtract the x-values. 0-(-2)= 2
3rd: you have -6/2.
4th: simplify to get a slope of -3.
