Answer: x=-3 or x=0

Factor the quadratic

2x(x+3)=0

Equate each factor to 0 and solve for x

2x=0

x=0

Mumz [18]

Answer: $4,365.10

Step-by-step explanation:

Ok, we know that:

The account starts with $2350

There is a simple interest of 3.75% (or 0.035).

Then after one year, the amount in the account will increase by 3.75%, this means that the amount will be:

$2350 + 0.035*$2350 = (1.035)*$2350.

After another year, we have the same increase (but applied to the new amount in the account):

(1.035)*$2350 + 0.035*(1.035)*$2350. = (1.035)^2*$2350

And so on.

You already can see the pattern here, the amount of money in the saving account after N years will be:

M(N) = $2350*(1.035)^N.

Now we can answer:

what is the balance of the account if it earns a  simple interest of 3.75% for 18 years?

Just replace N by 18 in that equation:

M(18) = $2350*(1.035)^18 = $4,365.10

The graph of the parent function f(x) = x is transformed such that g(x) = f(-2x). How does the graph of g(x) compare to the
Verdich [7]

Answer:

  • reflected across the y-axis
  • compressed by a factor of 2

Step-by-step explanation:

Replacing x by -x in f(x) causes it to be reversed horizontally, that is, reflected across the y-axis.

Replacing x by 2x in f(x) causes it to be compressed horizontally by a factor of 2.

Both of these transformations result in g(x) being a horizontally compressed horizontal reflection of f(x).

See the attachment for an example. The blue curve is g(x); the red curve is f(x).
