Answer:

  A) The graph is the quadrant of the coordinate plane that lies between the two lines and to the left of the point (-2 14/15, 1 1/5)

  B) no; it does not satisfy either inequality

Step-by-step explanation:

A) The boundary line defined by the first inequality is a dashed line with a slope of 3 and a y-intercept of 10. Shading is above the line (and to its left).

The boundary line defined by the second inequality is a dashed line with a slope of -3/4 and a y-intercept of -1. Shading is below the line (and to its left).

The two lines cross at the 2nd-quadrant point (-2 14/15, 1 1/5). The solution area is the area between the crossing lines and to the left of that point. Neither that point nor any point on either line is part of the solution area.

The solution area is the doubly-shaded area in the attached graph.

__

B) The first-quadrant point (8, 10) is not in the solution area, since the solution area is comprised of parts of quadrants 2 and 3 only.

We can see that (8, 10) will not satisfy either inequality:

  10 > 3(8) +10 . . . . not true

  10 < -3/4(8) -1 . . . . not true

Answer:

length of rectangle = 4 units

width of rectangle = 3 units

Perimeter of a rectangle = 14 units

Step-by-step explanation:

Properties of a rectangle:

From inspection, we can see that (2, 2) and (2, 6) have the same x-values.  So (2, 6) is above (2, 2) on the same vertical line.  

To calculate the distance between them, find the difference between their y-values:  6 - 2 = 4

Therefore, one pair of sides of the rectangle are 4 units in length.

From inspection, we can see that (2, 6) and (5, 6) have the same y-values.  So (5, 6) is to the right of (2, 6) on the same horizontal line.  

To calculate the distance between them, find the difference between their x-values:  5 - 2 = 3

Therefore, the other pair of sides of the rectangle are 3 units in length.

Therefore:

Perimeter of a rectangle = 2 × length + 2 × width

                                         = 2 × 4 + 2 × 3

                                         = 8 + 6

                                         = 14 units

Step-by-step explanation:

Answer:

Greatest = 98,321

Least= 12,389

98,321>12,389

Step-by-step explanation:

there are only 5 digits. To get the greatest number, the digits with the most value should be put in front to ensure the great value.

To get the smallest number, the digits with the least value should be put in front.

The greater valued number is greater than the least valued number

The number string is an illustration of the addition operation

The number string that corresponds to the text “Hello Raya” is 97

The text is given as:

“Hello Raya”

From the table in the complete question, we have the following representations:

H = 8; E = 5; L = 12; O = 15; R = 18; A = 1; Y = 25; _ or space = 0

The sum of the numerical values of the characters are:

Sum = 8 + 5+ 12 + 12 + 15 +0 + 18 + 1+ 25 + 1

Evaluate the sum

Sum = 97

Hence, the number string that corresponds to the text “Hello Raya” is 97

Answer:

To find the surface area of this parallelepiped, we need to know how to find the area of a regular parallelogram.

Formula for area of a parallelogram;

A = BH

Where b represents the base, and h displays as the height.

Once, we know how to find the area of a parallelogram, we find the areas of the three different sides of this figure and multiply it by two since opposite sides have an equal area.

Now we find the area of the front parallelogram:

A = BH

Plug in our values;

A = 4(2)

A = 8, and since opposite sides are equal:-

8(2) = 16, is the area of both the front and back parallelograms.

Now the top and bottom bases of this parallelepiped.

But, to find the height and base of this, we transfer the base of the front parallelogram and the base of the right parallelogram. So our base and height is 4.

A = BH

Plug in our values;
A = 4(4)

A = 16, and since opposite sides are equal:-

16(2) = 256, is the area for both the upper and bottom bases.

Now for the right and left parallelograms;

A = BH

Plug in our values;

A = 4(2.5)

A = 10, since opposite sides are equal:-

10(2) = 20, is the area of both the right and left parallelograms.

Now we add all the areas together:

16 + 256 + 20

= 292 square meters.

Answer:

Using distributive property you jsut multiply the number outside the parenthesis by each number inside.
In this case its
1/2 ( p + 4)

So multiply each number (or variable) by 1/2

And leave the sign if nothing changes

1/2 * p = 1/2p

1/2 * 4 = 2

You’d get
1/2p + 2

Answer:

1/2

Step-by-step explanation:

7/10 - 1/5

=> 7/10 - 1*2/5*2

=> 7/10 - 2/10

=> (7-2)/10

=> 5/10

=> 1/2

first, you have to make sure they have the same bottom number so you would make 1/5 2/10.

7/10-2/10

which is 5/10

you would simplify it and get 1/2 because 5 is half of 10

it going to be number three

Answer:

[tex]2 (x^2+3x+18)[/tex]

Step-by-step explanation:

The missing number that will make both expressions to be equivalent expressions is: 110.

Two expressions are equivalent if they have the same value.

Given the following expressions:

Let x represent the missing number in the second expression. Thus, equate both expressions and solve for x.

200r -(-110) = x + 200r

200r + 110 = x + 200r

Add like terms

200r - 200r + 110 = x

110 = x

x = 110

Therefore, the missing number that will make both expressions to be equivalent expressions is: 110.

Percentage change = ?

Solution:

The percentage change is the difference between the final and initial value divide by the initial value multiplied by 100;

      Percentage change  = [tex]\frac{Final value - Initial value}{Initial value} x 100[/tex]

  Input the parameters and solve;

  Percentage change = [tex]\frac{31 - 27}{27} x 100[/tex]

the roots are: -1.3, 0.8

Step-by-step explanation:

the graph displayed is what is known as a quadratic

the turning point of a quadratic is the bottom of the line (where the line stops going down and starts going up)

the roots of a quadratic graph is where the line crosses the x axis (there are usually two roots but sometimes there are none).
