What type of number is - v 81?

Answer:

x<10

Step-by-step explanation:

Isolate X:

2x-8+8<12+8 = 2x<20

Then divide by 2:

2x/2<20/2 = x<10

x<10

Answer:

2 x-intercepts at 3 and 9

Step-by-step explanation:

x^2-12x+27=0

(factoring)

(x-3)(x-9)=0

this tells us that there is going to be a x-intercept at both 3, and 9, and that there is no stretching of it. It would look like this.

Answer:

[tex]b = 8[/tex]

Step-by-step explanation:

First, cross multiply across the equal sign. Note that what you do to one side, you do to the other:

[tex](b+10)(2b-7)(\frac{8}{b+10}) = (\frac{4}{2b -7})(b+10)(2b-7)\\ \\(2b -7)(8) = (4)(b+10)[/tex]

Next, distribute 8 and 4 to their corresponding parenthesis:

[tex]8(2b -7) = 16b - 56\\4(b + 10) = 4b + 40[/tex]

[tex]16b - 56 = 4b + 40[/tex]

Next, isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 56 and subtract 4b from both sides:

[tex]16b (-4b) - 56 (+56) = 4b (-4b) + 40 (+56)\\16b - 4b = 40 + 56\\12b = 96[/tex]

Isolate the variable, b. Divide 12 from both sides:

[tex]12b = 96\\\frac{12b}{12} = \frac{96}{12} \\b = \frac{96}{12} \\b = 8[/tex]

[tex]b = 8[/tex] is your answer.

Answer:

Hello, It isn't clear.

It looks blur to me

Answer:

7. C

8. A

To find slope, we need two points. Once we have them, we can put them into the formula:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]      ← this is rise/run

For 7, it's just a matter of comparing any two consecutive points.

For 8, you are given the two points.

Answer:

The simplified expression is : -9c +1

Step-by-step explanation:

The like terms are -8c and -c

The constant term is 1

The simplified expression is :

-8c + -c + 1 = -9c +1

Step-by-step explanation:

In this problem we will estimate her monthly earnings

given that she earns $13.05 per hour

and also given that she works for 190 hours in a month

then in a month, her earnings will be

=$13.05*190

=$2479.5

alternatively,

per week she works 47.5hours

in a week she will earn 13.05*47.7= $622.485

4 weeks make a month

then after one month her earning will be

$622.485*4= $2479.5

Answer:

x = [tex]\frac{4}{3}[/tex]  

Step-by-step explanation:

Rectangle:

Length = 3x feet

Width = 4 feet

Perimeter = 2*(length +width)

                = 2* (3x + 4)

                = 2*3x + 2*4

                 = 6x + 8

Area = length * width

        = 3x * 4

        = 12x

Area of rectangle =  perimeter of rectangle

                       12x = 6x + 8              {Subtract 6x form both sides}

               12x - 6x  = 8

                       6x = 8                    {Divide both sides by 6}

                         x = 8/6

                         x = [tex]\frac{4}{3}[/tex] feet

The number is equal to 25.

To write the word problem as an algebraic equation:

In this exercise, we are required to translate the word problem into a mathematical (algebraic) expression and solve for the unknown variable (number):

Translating the word problem into an algebraic expression, we have;

A number is doubled and then increased by 20:

i can explain it to you if u want

Step-by-step explanation:

Divide the polygon into 5 triangles by using each side as a base and joining the vertices of the polygon to a common point (for example, the centre). If the polygon is regular the angle at the vertex of each triangle is 360/5=72 degrees, so you have 5 isosceles triangles of equal area. Find the area of one and multiply by 5 to get the total area.multiply 5 times the lenght of oneside

Answer:

Answer: x is greater than 9 x>9

Step-by-step explanation:

You see -4 times 9 equals to -36. And -36+plus 40 equals to -4. The question is asking you to make sure the left side is greater. So, it has to be greater than 9. for example -4 times 8 equals to -32. And -32+40 equals to 8. So your answer is X>9. I hope that helped you.

The answer is [tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]

First, you must flip the equation

[tex]12k+29[/tex] ≥ [tex]120[/tex]

Then, you must subtract 29 on both sides

[tex]12k[/tex] ≥ [tex]91[/tex]

Finally, divide both sides by 12

[tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]
