The answer is f(x) = 5(2/4)^x, which is the fourth answer choice.

Based on the graph you can see that f(1)=2, and if you plug in 1 for each of the functions listed, the only one that gives you 2 is f(x) = 5(2/4)^x

Reading the situation, I can say that Jared and Nicole are correct because they manipulated the equation right. They can either write the equation as y as a function of x then substitute it to the y in the other equation and solve for x. They can also write the equation as x as a function of y and substitute it to x in the other equation and solve for y. For both solution, they will still obtain the same answers.

He is wrong because as long as they have the same terms/ variables behind the number it doesn’t matter about if it is positive or negative

**Answer: choice D**

**Step-by-step explanation:**

An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.

in this exampke the constant(d) is -3

Answer:

£1999.85

Step-by-step explanation:

A = P(1 + rt)

Where:

A = Amount after t years

P = Initial amount invested = £1850

r = Interest rate = 2.7%

t = Time in years = 3 years

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.7%/100 = 0.027 per year.

Solving our equation:

A = £1850(1 + (0.027 × 3))

A = £1999.85

Therefore, Brian will have £1999.85 after 3 years.
