The value of <u>a</u> is 2 and the value of <u>b</u> is 6.

<h3>Factoring</h3>

In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization.  One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.

You should factor the given expression.

2-\frac{x+3}{x+1}-\frac{x-5}{x-1}\\ \\ 2+\frac{-\left(x+3\right)\left(x-1\right)-\left(x-5\right)\left(x+1\right)}{\left(x+1\right)\left(x-1\right)}\\ \\ \mathrm{Apply\:the\:fraction\:rule}:\quad \:a+\frac{b}{c}=\frac{ac+b}{c}\\ \\ \frac{2\left(x+1\right)\left(x-1\right)-\left(x+3\right)\left(x-1\right)-\left(x-5\right)\left(x+1\right)}{\left(x+1\right)\left(x-1\right)}\\ \\ \frac{2x+6}{\left(x+1\right)\left(x-1\right)}=\frac{2x+6}{x^2-1}

Identify the domain of the function shown in the graph.
Leno4ka [110]

Domain is set of all x-values. You are supposed to focus on the x-axis instead.

From the graph, the point starts from x = -5 and ends on x = 5. That means no values would exist after x = 5 or before x = -5.

Hence, the domain starts from -5 to 5.

Answer

  • -5≤x≤5

If $560 is invested at an interest rate of 9% per year and is compounded continuously, how much will the investment be worth in
koban [17]

Answer:

$878.25

Step-by-step explanation:

Continuously compounded interest is:

A = Pe^(rt)

where A is the final amount, P is the initial amount, r is the interest rate, and t is the number of compoundings.

Here, P = 560, r = 0.09, and t = 5.

A = 560e^(0.09×5)

A = 878.25

What’s the answer to this question?
NemiM [27]

Answer:

y=1/2x

Step-by-step explanation:

The slope of the line goes up by 1 over by 2 each time or 1/2. (Rise over run)

This can be proven by substituting X and Y for a point on the graph.

y=5, x=10

5=1/2(10)

5=5
