Ryan invested $4,800$4,800 in an account in the year 1990, and the value has been growing exponentially at a constant rate. The value of the account reached $6,300$6,300 in the year 1998. Determine the value of the account, to the nearest dollar, in the year 2007.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
