What is the rate of change for the linear relationship modeled in the table?
x y
-1 10
1 9
3 8
5 7
A -1/2
B 0
C 1/2
D 2​

Answers

Answer 1

Use the first and lay set of x,y values.

Rate of change is change in y/ change in x:

7-10 / 5- -1 = -3/6 = -1/2

The answer is A.-1/2

Answer 2
A.-1/2 is the answer due to the fact that the rate of change is y/x. The rate at which the y values are changing is -1, and the rate at which the d values are changing is +2. Put them together, -1/2. Hope this helps

Answers

Answer:

y =  1/2x + 4 1/2

Step-by-step explanation:

(9 , 9) (3 , 6)

slope (m) = Rise (Δy) /run (Δx) = (9-6) / (9-3) = 3/6 = 1/2

(y-6)/(x-3) = 1/2

y-6 = 1/2 (x-3) = 1/2x - 3/2

y = 1/2x + 9/2 = 1/2x + 4 1/2

The net of a triangular prism is shown. Use the ruler provided to measure the dimensions of the net to the nearest half centimeter. Which measurement is closest tot he total surface of the triangular prism in square centimeters.?

Answers

Answer:

The total surface area of the figure is 516 square units.

Step-by-step explanation:

The net of the triangular prisms is attached. Remember, the total surface area refers to the area of each face of the volumetric figure. In this case we have 3 equal rectangles and 2 equal triangles.

The Area of the rectangles.A^1 = 3 (10 x 14) = 3 (140) = 420 u^2

   2. The Area of the triangles.

A^2 = 2(1/2 x 12 x 8) = 96 ^2

The total surface area is given by the sum of all these areas:

S= 420 + 96 = 516 u^2.

Using the variable n for the term, describe the sequence.

Answers

Answer:

3 + 5n

Step-by-step explanation:

This is an arithmetic sequence.

First term = a = 8

Common difference = d =Second term - first term

                                = 13 - 8

                                 = 5

Nth term = a + (n- 1)*d

              = 8 + (n -1) * 5

             = 8 + n*5 - 1 *5

              = 8 + 5n - 5

               = 8 - 5 + 5n

                = 3 + 5n
