I'm pretty sure it would be y=2x+9
Answer: 1 : 1.48
Step-by-step explanation:
Adam was able to change £400 into 592 francs which means that the British pound is stronger because it was able to buy more Swiss francs.
The exchange rate can be gotten using direct proportion:
400 : 592
1 : x
Cross multiply:
400x = 592
x = 592/400
x = 1.48
Exchange rate is:
= 1 : 1.48
F(-1) = 12 - 5(-1)
f(-1) = 12 + 5
Solution: f(-1) = 17
Hope I helped you. You didn't even asked any question.
