Write the coordinates for the given dilation
kenny6666 [7]

<u>Answer:</u>

D_o of Y = (-3/2, -1)

<u>Step-by-step explanation:</u>

We are given three points on the graph:

X (4, 0)

Y (3, 2)

Z (2, 2)

and the scale factor of dilation which is -\frac{1}{2}.

Given that, we are to find the coordinates of Y after dilation. To find that, we will multiply the coordinates of the point Y with the scale factor.

Y =  (-\frac{1}{2} × 3 , (-\frac{1}{2}[/tex] × 2)

Y = (-\frac{3}{2} , -1)

vagabundo [1.1K]

Answer:

The amount of sales in order to meet her goal must be greater than or equal to $20,000

Step-by-step explanation:

Let

x----> represent the amount of sales Liz will need

we know that

The amount of sales for the month multiplied by the commission rate as a decimal plus the fixed amount must be greater than or equal to $2,800 each month

so

The inequality that represent this situation is

0.03x+2,200\geq 2,800

solve for x

subtract 2,200 both sides

0.03x \geq 2,800-2,200

0.03x \geq 600

divide by 0.03 both sides

x \geq \$20,000

The amount of sales in order to meet her goal must be greater than or equal to $20,000

Every female chicken lays 4 eggs. What is the constant of proportionality for the ratio of eggs to female chickens? 4 3
satela [25.4K]

Since every female chicken lays 4 eggs, if you have one chicken you have 4 eggs, if you have two chicken you have 8 eggs, and so on.

We can even build a little table to show some values:

\begin{array}{c|c}1&4\\2&8\\3&12\\4&16\\5&20\\\vdots & \vdots\\n& 4n\end{array}

So, as you can see, the ratio between the number of eggs and the number of female chicken is 4.
