Answer:
Terry initially had £390
Step-by-step explanation:
The ratio of the original amount is 3:7
Let the original amount Terry has be t and the original amount Faye has be f
3/7 = t/f
or simply 3f = 7t ••••••(i)
Terry putting 220 means he now has
t + 220
Faye withdrew 300
He now has f-300
These values are equal
t + 220 = f-300
f = t+220+300
f = t + 520 ••••••(ii)
Put ii into i
3(t + 520) = 7t
3t + 1560 = 7t
7t-3t = 1560
4t = 1560
t = 1560/4
t = 390
Answer:
<u>D.</u>
Step-by-step explanation:
You just have to try it out for some points. I tried it for (-4,-3), (0,0), (7,0)
Whenever we have a negative exponent, that means that the function should be in the denomenator. then the exponent will be positive.
Example
16^-4 = 1/(16^4)
Answer:
-2
Step-by-step explanation:

9g=-18
g=-2
