The domain of the expression is all real numbers expect where the expression is undignified. In this case there is no real number that makes expression undefined. The range is the best set of all valid y values.

Can someone please help me?

Vladimir79 [104]

Answer:

Option D is the correct option.

Step-by-step explanation:

y = - 2x - 3 → Equation ( i )

y = 3x + 2 → Equation ( ii )

Using elimination method

y + 2x = - 3

y - 3x = 2

---------------------

5x = - 5

Divide both sides of the equation by 5

$\frac{5x}{5} = \frac{ - 5}{5}$

Calculate

$x = - 1$

Again, Putting the value of x in equation ( ii ) in order t get the value of y

$y = 3x + 2$

plug the value of x

$= 3 \times ( - 1) + 2$

Any expression multiplied by ( - 1 ) equals it's opposite

$= - 3 + 2$

Calculate

$= - 1$

Therefore, The possible solution of the system is the ordered pair ( x , y )

$(x \:, y \: ) = ( - 1 \:, - 1)$

-----------------------------------------------------------------------

Check if the given ordered pair is the solution of the system of equation

$- 1 = - 2 \times ( - 1) - 3$

$- 1 = 3 \times ( - 1) + 2$

Simplify the equation

$- 1 = - 1$

Since all the equalities are true, the ordered pair is the solution of the system.

Hope this helps..

Best regards!!

How many years will it take for the account to reach $18,600? Round your answer to the nearest hundredth

Margarita [4]

<span>it depends how the interest is calculated, but there's not much of a difference

assuming its continuously compouned, you use this formula: A(t)=Pe^(rt), where A is the final amount, P is the initial investment, r is the interest, and t is the time in years

you want to find t such that A(t)=18,600 so 18,600=1000e^(.0675t)

you need to use logarithm to figure it out, take the natural log of both sides

the following properties will come into use:

ln(a*b)=ln(a)+ln(b)
ln(a^b)=bln(a)
ln(e)=1

taking the natural log

ln(18,600)=ln(1000e^(.0675t))

ln(18,600)=ln(1000)+ln(e^.0675t)

ln(18600)=ln(1000) + .0675t

now solve for t: t= (ln(18600)-ln(1000))/.0675

t=43.31</span>
