The vertices of a polygon are given as follows: P(-2,4), Q(4,2), R(4,0); S(-12,0); k = 0.5 Find the coordinates of the vertex P' of the image after a dilation having the given scale factor. Type your answers as a coordinate pair in this format: (x,y)</span>

If the center of dilation is the origin, you can just multiply each coordinate by the scale factor to find the new values.

P' will be (-1, 2)

If the center of dilation isn't the origin, my answer is invalid.

Let b and s be the velocity of the boat and stream respectively....

3(b-s)=27

b-s=9

b=9+s we will use this in the second equation....

2(b+s)=30

b+s=15, now use b found above in this to get:

9+s+s=15

2s+9=15

2s=6

s=3, and since from earlier b-s=9, b=9+s so

b=12

So the speed of the boat is 12mph and the stream is 3 mph

Can i have some help

Answer:

b. m = 2, b = 4

Step-by-step explanation:

y = mx + b

m = slope and b = y-intercept

The slope is 2 cause it's going up 2 squares while only going to the right one square each time, so u could right 2/1 but it's not necessary so just 2. And the intercept is 4 because that's where the line intercepts the y-axis.

Draw clearly the graph of the linear equation. y=1/2x, where x= (-4 -2, 0, 2, 4)

Answer:

(in attachment)

Step-by-step explanation:

you can find the points by inputting the x-values into the equation to solve for the y-values, then connecting the plotted points to create the line.

When x=-4

y=1/2(-4)

y=-2

(-4,-2)

Repeat for all values.

Hi,

Rectangular prism or Cuboid has a volume that can be calculated by multiplying it's dimensions.

$v = l \times w \times h$
In your case...

$v = 5 \times 3 \times 4 = {60}^{3}$
Answer = 60m3

Hope this helps.
