Answer:
y= -4(x-4) +1
Step-by-step explanation:
Use the equation y=m(x-x(sub 1))+(sub 1)
Answer:
See image below:)
Step-by-step explanation:
For this case we have the following function:
f (x) = 2x + 5
Clearing x we have:
2x = y - 5
x = (y-5) / 2
Rewriting:
f (x) ^ - 1 = (x-5) / 2
Evaluating x = 8:
f (8) ^ - 1 = (8-5) / 2
f (8) ^ - 1 = 3/2
Answer:
f (8) ^ - 1 = 3/2
option 2
Answer: A
Step-by-step explanation: A because it corresponds to the other black dots but if you do B or C, it wouldn't work because it doesn't correspond to them.
If he decides to save 10% he decided to save 38.75 since 387.50×.10 is 387500 (move decimal 4 times to figure out what the percentage of 387.50 is since the $ already has 2 numbers after the decimals and so does .10 which =38.75 this is what he saves so subtract this from 387.50 to find out what he has left to spend
387.50-38.75= 348.75
