Point slope form- y-4=(x+2)
Slope intercept- y=x+6
B. x > 3Took a while, but there you go xD
Answer:
- Melissa: 30
- Ryan: 23
- Chau: 69
Step-by-step explanation:
Let r represent the number of messages Ryan sent. Then Chau sent 3r and Melissa sent r+7. Their total was ...
(r+7) +(r) +(3r) = 122
5r +7 = 122 . . . . . collect terms
5r = 115 . . . . . . . . subtract 7
r = 23 . . . . . . . . . . divide by 5
Ryan sent 23, Melissa sent 30, and Chau sent 69 text messages.
3x(5x+6)-8(1+8x)
15x^2+18x-8-64x
15x^2-46x-8 is your final answer
