Answer: 7:49

Step-by-step explanation: As you can see in the table, if you divide the number of fans present at a football game by the number of students, you would always get 7. So, 7:49 is a choice because if you divide 49 by 7, you get 7. Hope this helps!!

The length of a rectangle is 11 in. longer than its width. the perimeter of the rectangle is 86 in.write and solve an equation t
Tcecarenko [31]
I hope this helps you


width w


length w+11



perimeter =2 (width +length )


86=2 (w+w+11)


43=2w+11


32=2w


w=16

length = w+11=16+11=27

Find the minimum value of C=x+y subject to the following constraints<br> Please help me!!
hram777 [196]

Answer:

The minimum value of C is 14

Step-by-step explanation:

Sketch the graph of the constraints using

2x + y = 20

with intercepts (0, 20) and (10, 0)

2x + 3y = 36

with intercepts (0, 12) and (18, 0)

The solution to both are above the lines

Solve 2x + y = 20 and 2x + 3y = 36 to find the point of intersection at (6, 8)

Then the coordinates of the vertices of the region formed are

(0, 20), (6, 8) and (18, 0)

Evaluate the objective function at each vertex to determine minimum value

C = 0 + 20 = 20

C = 6 + 8 = 14

C = 18 + 0 = 18

Thus the minimum value of C is 14 when x = 6 and y = 8

Write parametric equations of the line 9x + y = -1
iris [78.8K]

Step-by-step explanation:

Parametric equations of the line,  9x + y = -1

Assign any one of the variables equal to s. (say x = s).

By substituting the value x=s in the given equation,

        The equation can be rewritten as  9s + y= -1

         Set of parametric equations is x = s and

                                                             y=  -9s- 1 (or) y= -(9s + 1)

Answer:

  see attached

Step-by-step explanation:

13. The difference of two matrices is the term-by-term difference. For example, the bottom right term is the difference of the bottom right terms ...

  (-6) -(5) = -11

__

14. The scalar multiple of a matrix is the scalar multiplied by each term of the matrix. For example, the upper right term is ...

  3(1) = 3

__

15. The matrix product is the dot product of the rows of the left matrix with the columns of the right matrix. For example, the product term in row two, column one is the dot product of row 2 of C and column 1 of B:

  [9, -2, 4]·[-2, -7, 10] = 9(-2) +(-2)(-7) +4(10) = -18 +14 +40 = 36

_____

It is convenient to let an appropriate tool help with this. Many graphing calculators and spreadsheets are able to do these functions easily.
