Answer:

reflection over y = 2.5
translation left 1

Step-by-step explanation:

The orientation of the triangle is reversed, so a reflection is required. Horizontal lines remain horizontal, but up/down are reversed, so the reflection is across a horizontal line. The horizontal line that is halfway between each point and its image is the line y = 2.5.

The x-coordinates of the image points are 1 less than the x-coordinates of the original, so a left shift of 1 unit is involved.

The two transformations to get from A to B could be (in any order) ...

reflection over the line y = 2.5
translation left 1 unit

__

The transformation can be summarized by ...

(x, y) ⇒ (x -1, 5 -y)

Consider the points.

miskamm [114]

Answer:

6 units

Step-by-step explanation:

Use the distance formula, $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$ .

Plug the x and y values from the given points into the distance formula:

$\sqrt{([-4]-2)^{2}+(5-5)^{2}}$ .

Solve the square root:

$\sqrt{36}$ = $\sqrt{6^{2}}$ = $6$

The table shows the number of toys sold at Penelope's Toys and Games store in different years. Find the rate of change in the nu

Aliun [14]

Answer:

Year - (1993 - 1995)

Step-by-step explanation:

Rate of change in the number of toys sold = $\frac{\text{change in number of toys sold}}{\text{Time interval}}$

In the interval (1990 - 1993),

Rate of change in number of toys sold = $\frac{32000-20000}{1993-1990}$

= $\frac{12000}{3}$

= 4000

In the interval (1993 - 1995),

Rate of change = $\frac{42000-32000}{1995-1993}$

= $\frac{10000}{2}$

= 5000

In the interval (2000 - 1995),

Rate of change = $\frac{57000-42000}{2000-1995}$

= $\frac{15000}{5}$

= 3000

In the interval (2006 - 2000),

Rate of change = $\frac{63000-57000}{2006-2000}$

= $\frac{6000}{6}$

= 1000

Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).
