what is the product of x and y

Answers

Answer 1
I think it would be (8)(-1) = -8. by adding the two equations you get 2x = 16 so x = 8 then y = 7 - x = -1. Therefore xy = -8.

[tex]( - 5) \times 2 = - 10 \\ - 10 = - 10[/tex]

putting x = -2

[tex]( - 5) \times ( - 2) = - 10 \\ 5 \times 2 = - 10 \\ 10 = - 10 \\ this \: is \: not \: correct \: equation[/tex]

putting x = 50

Answers

Answer:

CM = 16

MD = 16

CD = 32

Step-by-step explanation:

To find the value of x

3x + 1 = 8x - 24 (we know that M is the mid point so both of the lines will be equal)

Transpose

1 + 24 = 8x - 3x

25 = 5x

x = 25/5

x = 5

CM = 3x + 1

      = 3(5) + 1

      = 15 +1

     = 16

MD = 8x - 24

       = 8(5) - 24

       = 40 - 24

       = 16

CD = CM + MD

      = 16 + 16

      = 32

Answers

Coordinates of B is [tex](\frac{4}{11} ,\frac{13}{11} )[/tex] that divides AC five-sixths of the way from A to C

Given :

AC with A(4.-7) and C(-4, 11), if point B divides AC five-sixths of

the way from A to C

From the given information , B divides AC internally in the ratio of AB to BC is 5:6

Lets apply section formula to find coordinates of B

[tex](\frac{mx_2+nx_1}{m+n} ,\frac{my_2+ny_1}{m+n} )[/tex]

m:n is the ratio 5:6

A is (x1,y1) that is (4,-7)

B is (x2,y2) that is (-4,11)

Substitute the values inside the formula

[tex](\frac{mx_2+nx_1}{m+n} ,\frac{my_2+ny_1}{m+n} )\\(\frac{(5)(-4)+6(4)}{5+6} ,\frac{5(11)+6(-7)}{5+6} )\\(\frac{4}{11} ,\frac{13}{11} )[/tex]

For which value of x is the figure a rhombus?

A. X=6
B. X= 7.5
C. X=12
D. X=18.75

Answers

That is a question about properties of rhombus.

There is a property of a rhombus that says that the its diagonals divided the internal angles in two equals angles.

Now that we know about it, it is easier to solve this question, because now we know that [tex]2x+39[/tex] and [tex]6x - 9[/tex] are equal angles. So, we can make a equation and solve it:

[tex]2x+39 = 6x - 9\\39 + 9 = 6x - 2x\\48 = 4x\\4x = 48\\x=\frac{48}{4} \\x=12[/tex]

Therefore, the value of [tex]x[/tex] is 12. So, the correct alternative is letter C).

What is the average rate of change over the


interval [0.75, 1.125]? Explain the meaning


of the average rate of change.

Answers

Answer:

The average rte of change = 6

2) The average rate of change over an interval is the ratio of the total change in the determinate variable or function (values of the output of the function) to the change in the indeterminate variable (values of the input of the function)

Step-by-step explanation:

1) The average of change of the function is found as follows;

At x = 0.75, y = -0.5, at x = 1.125, y = 1.75

Therefore, the average rate of change = (1.75 - (-0.5))/(1.125 - 0.75) = 6

2) The average rate of change over an interval on a graph or of a curve is found by dividing the difference between the y-coordinate values of the two points on the graph by the difference of the x-coordinate values of the two points.

Step-by-step explanation:

If 8 years are subtracted from the present age of Jessica and 3 is added to the remaining number, then Olivia’s age can be found. If Olivia is two years older than Daniel who is 7 years old, then what is Jessica’s present age?

Answers

Answer:

Jessica is 14 years old.

Step-by-step explanation:

Let [tex]o[/tex] equal Olivia's age, let [tex]j[/tex] equal Jessica's age, and let [tex]d[/tex] equal Daniel's age. With this lets write out what we know:

[tex]d = 7[/tex]

[tex]o = d + 2 = 7 + 2 = 9[/tex]

[tex]o = j - 8 + 3 = j - 5[/tex]

[tex]9 = j - 5[/tex]

[tex]j = 9 + 5 = 14[/tex]
