Take the formula: y=mx+b
m= slope
b=y-intercept

The price of gasoline increased 25% from July to August. If c = cost of gasoline in July, write two expressions that represent t

inessss [21]

Answer:

Wrote it in the explanation :)

Step-by-step explanation:

Expression One: c + 25% = price of gas in august

Expression Two: c + 0.25 = price of gas in august

Expression Two would be easier to use if we knew "c" because the numbers are already in decimal form. If it were in percentage form, it would cause us an extra step to convert it into a decimal.

Please tell me if you have any further questions...

Hope this helped!!

Joann invested $43,000 at 6% to be compounded annually. What will be the value of Joann's investment in 2 years? Round your answ

kaheart [24]

Answer:

<u>The total amount after 2 years of Joann's investment at a rate of 6% compounded annually is US$ 48.314.80 (rounded to the nearest cent)</u>

Step-by-step explanation:

1. Let's review the data given to us for answering the question:

Investment amount = US$ 43,000

Duration of the investment = 2 years

Annual interest rate = 6% compounded annually

2. Let's find the future value of this investment after 2 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Investment = US$ 43,000

number of periods (n) = 2 (2 years compounded annually)

rate (r) = 6% = 0.06

Replacing with the real values, we have:

FV = 43,000 * (1 + 0.06) ²

FV = 43,000 * (1.06) ²

FV = 43,000 * 1.1236

F(x) = 2(x + 3), now if we distribute the 2, we get 2x + 6.

we know the lbs of apple is "x", and therefore, the lbs of orange will be the constant 3.

2x will then stand for the price for "x" lbs of apples.

and 2*3 will stand for the price of "3" lbs of oranges, which is 6 bucks.

since the 2 is multiplying the lbs quantity, it must then be the price, so both cost 2 bucks each per pound.
