11. D'(2.9) is the image of D after a reflection

Mathematics

algol [13]3 years ago
4 0

Answer:

D(- 2, 9 )

Step-by-step explanation:

Under a reflection in the y- axis

a pont (x, y ) → (- x, y )

Given D'(2, 9 ) is the image of D, then

D(- 2, 9 ) ← are the original coordinates

Since D(- 2, 9 ) → D'(2, 9 )

Whitepunk [10]

Answer:

12

Step-by-step explanation:

Which graph represents the function y = 2x – 4? A coordinate plane with a line passing through (negative 4, 0) and (0, 2). A coo
VARVARA [1.3K]

Answer:

The third option: "A coordinate plane with a line passing through (0, negative 4) and (2, 0)."

Step-by-step explanation:

Use the equation defined by the function: y = 2x - 4 to check the (x, y) values they give you. If they both render true mathematical statements, those are indeed points on the plane that belong to the given line.

For the third case; the pairs (0,-4) and (2,0), both satisfy the equation of the line that is given.

For (0,-4):  y = 2x - 4 becomes:

(-4)=2(0)-4\\-4=0-4\\-4=-4 which is a TRUE statement

For (2,0):  y = 2x - 4 becomes:

(0)=2(2)-4\\0=4-4\\0=0 which is also a TRUE statement.

This option is the only one that verifies both given points as truly being part of the given line.

Jocelyn is training for a race by running several miles each day. she tracks her progress by recording her average speed in minu
Luden [163]

Finding the regression equation, her average speed on the 9th day should be expected to be of 6.92 minutes per mile.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

Researching the problem on the internet, the values of x and y are given as follows:

  • Values of x: 1, 2, 3, 4, 5, 6.
  • Values of y: 8.2, 8.1, 7.5, 7.8, 7.4, 7.5.

Hence, using a calculator, the equation for the average minutes per mile after t days is given by:

V(t) = -0.15143t + 8.28

Hence, for the 9th day, t = 9, hence the estimate is:

V(9) = -0.15143(9) + 8.28 = 6.92 minutes per mile.
