Step 1: –10 + 8x < 6x – 4

vesna_86 [32]

The final step in solving the inequality is to divide through by -2 and flip the sign

<h3>Solving Inequalities </h3>

From the question, we are to determine the final step in solving the inequality

The given inequality and the steps for solving are

Step 1: –10 + 8x < 6x – 4

Step 2: –10 < –2x – 4

Step 3: –6 < –2x

The final step will be to divide both sides of the inequalities by -2 and then flip the sign

That is,

–6 < –2x

Divide both sides by -2 and flip the sign

3 > x

x < 3

Hence, the final step in solving the inequality is to divide through by -2 and flip the sign

Consider the function f(x) = the quantity x squared minus x minus 12 all over the quantity x plus 3. Describe the graph of this

FromTheMoon [43]

Answer:

The graph of f(x) is discontinuous at x= -3. The x and y-intercepts or he function f(x) are (4,0) and (0,-4) respectively. The graph of the function is a straight line.

Step-by-step explanation:

The given function is

$f(x)=\frac{x^2-x-12}{x+3}$

$f(x)=\frac{x^2-4x+3x-12}{x+3}$

$f(x)=\frac{x(x-4)+3(x-4)}{x+3}$

$f(x)=\frac{(x-4)(x+3)}{x+3}$

Cancel out the common factor (x+3).

$f(x)=x-4$

It is a linear equation and it will give a straight line.

Put x=0, to find the y-intercept.

$f(x)=0-4$

$f(x)=-4$

Therefore the y-intercept is (0,-4).

Put x=0, to find the x-intercept.

$0=x-4$

$4=x$

Therefore the x-intercept is (4,0).

At x= -3 the value of denominator is 0, therefore the function is undefined for x= -3.

As x approaches toward x=-3 from left and right, the value of function approaches towards y=-7.

The function is discontinuous at x= -3.

Answer:

I just took the assignment for this i was correct but this is what i put First you would evulate what is in parenthisis and then evalate what's in them so you do 3.50 and you add 1.74 and that equals 5.25. Then you add 9 plus 1.34 and you get 10.34 and after that you do 5.25 and 10.34 and that equals 15.59 then u take the 1/2 and add that and in total you get 16.09 sample answer was... Sample Response: First, add the decimals in the parentheses. Next, multiply that number by 0.5. Finally, add all the decimal numbers.

Hope this helps have a nice day just rember the step shown in video that's all u had to includde in this answer really but rember pendas hope i help thanks

You run a hotel with 1465 rooms. You currently have 296 rooms reserved by individuals and 651 rooms reserved by groups for a par

Tanya [424]

Answer:

Hotel is over booked by 140 rooms

Step-by-step explanation:

Total number of hotel rooms = 1465

number reserved by individuals = 296

number reserved by groups = 651

booking rates = 67% for individual , 56% for groups

<u>Determine if you are under booked or overbooked for the weekend </u>

let X represent the number of rooms booked by individuals

and Y represent the number of rooms booked by groups

number of reserved room for individuals

= 67% of X = 296

X = 67% + 33%

= 296 + ( (296 / 67 ) * 33 )

= 296 + 146 ≈ 442

number of rooms reserved for groups

= 56% of Y = 651

Y =( 651 / 56 ) * 100

≈ 1163

Total rooms booked = X + Y

= 442 + 1163 = 1605

<u>To determine if under booked or over booked </u>

Total rooms booked - Total number of hotel rooms

= 1605 - 1465

= 140 ( Your Hotel is over booked )
