Answer:

  see attached

Step-by-step explanation:

The boundary lines are drawn by considering the relation as an equation.

The first "equation" describes a line with slope -8/3 through the y-intercept point (0, 6). Another point on that line would be 8 units down and 3 units right of (0, 6), at (3, -2). Both inequalities include the "or equal to" case, so both boundary lines are solid lines.

Since we have y ≥ ( ), the shading is above the line.

__

The second "equation" describes a line with a slope of 5/3 through the y-intercept point (0, -7). Another point would be 5 units up and 3 units right of (0, -7), at (3, -2). Since we have y ≤ ( ), the shading is below the line.

That is, the solution region is in the right-hand quadrant of the X where the lines cross. It includes the lines themselves.

Find the perimeter of a regular pentagon with sides of (3x + 5).
kotegsom [21]

Answer:

  5(3x + 5)   or   15x + 25

Step-by-step explanation:

A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:

  P = 5(3x +5)

Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:

  P = 15x + 25

Find the Mean, Median and Mode of the data set:
Paul [167]

Answer:

Mode = 37

Mean = 26.1

median = 30

Step-by-step explanation:

have a good day!!!!

To find the mean add all then divide by how many are for example:

(8+ 32+ 41+ 6+ 36+ 10+ 37+ 31 +29+ 37+ 32+ 11+ 30+ 15+ 23+ 37+ 34+17+29) /19= 26.1

To find the mode find the number that most appear in the data set

To  find the median organiz the data set from in a crecent order then find the number in the middle.

The formula for finding the perimeter, P, of a rectangle with length l and width w is given. P=2l+2w
Ivenika [448]

Answer:

The formula to determine the length of rectangle with perimeter and width is L = \frac{P - 2W}{2}

Step-by-step explanation:

Given as :

The perimeter of rectangle = P

The length of rectangle = L

The width of rectangle = W

∵ Perimeter of rectangle given as P = 2 × Length + 2 × Width

I.e  P = 2 L + 2 W

Or, 2 L = P - 2 W

∴     L = \frac{P - 2W}{2}

Hence The formula to determine the length of rectangle with perimeter and width is L = \frac{P - 2W}{2}    Answer
