Answer:
The answer to your question is: first option
Step-by-step explanation:
Data
A (2, 5)
B (-2, -3)
Formula
Slope = m (y2 - y1)/(x2 - x1)
Line (y - y1) = m(x - x1)}
Process
m = (- 3 - 5) / (-2 - 2)
m = -8 / -4
m = 2
Substitution in line equation
(y + 3) = 2 (x + 2) Line equation
I believe the answer is a
Jo's Mobile Plan:
- Fixed monthly charge = £16
- Monthly 150 free minutes, post that 13p (or £0.13) per minute,
- Monthly 150 free texts, post that 15p (or £0.15) per text
Jo's mobile phone usage details:
- 170 minutes of calls
- 182 texts
Total Charges for Jo = Fixed Monthly Charge + Charges for Calls + Charges for Texts
⇒ Total Charges for Jo = 16 + (170-150) × 0.13 + (182-150) × 0.15
⇒ Total Charges for Jo = 16 + (20) × 0.13 + (32) × 0.15
⇒ Total Charges for Jo = 16 + 2.6 + 4.8
⇒ Total Charges for Jo = 23.4
Hence, Jo should be charged £23.4 for the month.
Answer:
Step-by-step explanation:
It would be 30.33 repeating.
You wanna simplify the expression first
5(3m+2p+m)
=15m+10p+5m
so B would be correct
