Answer: x-3y=3x

8y=6x8

y=6x

Step-by-step explanation:

<h2>Meaning of linear equation</h2><h3>A linear equation is a equation that goes at a constant pace and won't change overtime, so functions like x squared and functions that multiply x and y together doesn't go at a constant pace, there not linear equations, but functions like y=mx, M representing any constant, that is a linear equation, therefore    x-3y=3x</h3>

8y=6x8

y=6x

Greg deposited $4000 into an account with a 9.8% annual interest rate, compounded semiannually. Assuming that no withdrawals are
Dovator [93]

The number of years it would take $4000 to grow to $4616 is 2.92 years.

<h3>How many years would it take the investment to have a value of $4616?</h3>

When an amount earns compound interest compounded semi annually, it means that both the amount invested and the interest accrued increases in value twice yearly.

Number of years = (In FV / PV) / r

  • r = 9.8/2 = 4.90%
  • FV = future value = 4616
  • PV = present value = 4000

(In 4616 / 4000) / 0.049 = 2.92 years

What is the range of the function on the graph?all real numbersO all real numbers less than or equal to -1all real numbers less
Yuki888 [10]

The range of the function f(x) is the set of all values that function f takes.

The domain of the function f(x) is the set of all possible values for x.

From the given graph you can see that the domain is all real numbers, x\in (-\infty,\infty).

The maximal y-value that f takes is 3 at x=-1. For all another x from the domain, y is less than 3.

Thus, the range of the given function is y\in (-\infty,3].

Answer:  y\in (-\infty,3].
