Answers:

  • Domain is (-4, 3]
  • Range is (-5, 5]

=====================================================

Explanation:

The domain is the set of allowed x input values, aka the set of all allowed x coordinates of the points. We see that -4 < x \le 3. It might help to draw vertical lines through the endpoints until you reach the x axis. Note the open hole at x = -4 to indicate we do not include this as part of the domain (hence the lack of "or equal to" for the first inequality sign).

The interval -4 < x \le 3 then can be condensed into the shorthand form (-4, 3] which is the domain in interval notation.

It says: x is between -4 and 3. It can't equal -4 but it can equal 3.

So the use of parenthesis versus square brackets tells the reader which endpoint is included or not.

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

The range describes all possible y outputs. We see that y = 5 is the largest it gets and y = -5 is the lower bound. It might help to draw horizontal lines through the endpoints until you reach the y axis. The open hole means -5 is not part of the range.

The range as a compound inequality is -5 < y \le 5. This condenses into the shorthand of (-5, 5] which is the range in interval notation.

Verbally, the range is the set of y values such that y is between -5 and 5. It can't equal -5 but it can equal 5.

<h3>Answer:  89,58 $ </h3>

Step-by-step explanation:

The formula :

\displaystyle \rm S=A\cdot \left (1+\frac{N}{100}  \right  )^{\big r}

where r is years ; N is the percentage by which we increase the price ; A is the original price

In our case :

\rm r=1 \ \ ;  \ \  A=100 \ \ ;   \  \  N=7,5\% \\\\ S=1000\cdot \bigg(  1+\dfrac{7,5}{100} \bigg)^1=1000\cdot 1,075=\boxed{1075\$}

Then the monthly salary is equal to:

\dfrac{1075}{12} \approx 89,58 \$

Please help 2х -3y =18
siniylev [52]

Answer:

x = 3(6 + y)/2

Step-by-step explanation:

Solving for x

Add 3y to both sides.

2x = 18 + 3y

Divide both sides by 2.

x = 18 + 3y/2

Factor out the common term 3.

x = 3(6 + y)/2
