Answer:

\frac{2}{x-y}}

Step-by-step explanation:

This equation may look difficult, but let's take it step by step. We are given the equation \frac{3x+3y}{x^{2}-y^{2} } -\frac{1}{x-y}.

We can simplify this to \frac{3x+3y}{(x-y)(x+y)} -\frac{1}{x-y} through the difference of two squares formula. Now, we need to make the denominators the same, so:

\frac{3x+3y}{(x-y)(x+y)} -\frac{(x+y)}{(x-y)(x+y)}

We can finally combine the fractions since they have the same denominator:\frac{3x+3y - (x +y)}{(x-y)(x+y)}}

We distribute the negative:  \frac{3x+3y - x-y}{(x-y)(x+y)}}

From here, we combine like terms: \frac{2x+2y}{(x-y)(x+y)}}

There's still one more step, we can factor out a two from the numerator: \frac{2(x+y)}{(x-y)(x+y)}} so that we can cancel out the term (x+y).

We are left with \frac{2}{x-y}}

Answer:

f(-3) = g(-3)

Step-by-step explanation:

Let's look at each option to which one is true with regard to the given functions on the graph.

The option that is correct is the option that shows where the graph of f(x) and g(x) intercepts or cut across each other.

Now, take a look at the graph, the line of both functions intercepts at x = -3. At this point, the value of f(-3) and g(-3) is equal to -4.

Therefore: f(-3) = g(-3)

Li deposited $17,500 into a bank account that earned simple interest each year. After 2 years, he had earned $2975 in interest.
Nimfa-mama [501]
Let x is the interest rate

$17,500 * 2 * x = <span>$2975
</span>$35,000x = $2,975
x = $2,975/$35,000
<span>x = 0.085

0.085 * 100 = 8.5%

Answer: annual interest rate was 8.5%
