answer:

f (2) = 6

step-by-step explanation:

first plug in 2 as x
f(2) basically means x = 2

f (2) = 3(2)^0 - 2(2)^-1 + 4

solve the exponents and use PEMDAS

f (2) = 3(2)^0 - 2(2)^-1 + 4

f (2) = 3 - 1 + 4

2 to the 0th power is 1
3 times 1 is 3 so we get 3
2 to the power of -1 is 1/2 (it gets flipped)
-2 times 1/2 is -1 so we get 1
there is nothing to do with +4 so we bring it down
now, simply solve it using PEMDAS

f (2) = 3 - 1 + 4

f (2) = 2 + 4

f (2) = 6

Soleil and Malvin each work a job. Soleil starts with $700 and makes $100 per day. Malvin starts out with $200 and makes $120 pe

Goshia [24]

Answer:

Soleil and Malvin would have $ 5,000 all together after 13 days.

Step-by-step explanation:

Since Soleil and Malvin each work a job, and Soleil starts with $ 700 and makes $ 100 per day while Malvin starts out with $ 200 and makes $ 120 per day, to determine after how many days will they have at least $ 5000 all together it must be done the following calculation:

5,000 - 700 - 200 = 4,100

200X + 120X = 4,100

320X = 4,100

X = 4,100 / 320

X = 12.8

So Soleil and Malvin would have $ 5,000 all together after 13 days.
