Answer:

below

Step-by-step explanation:

The point N is at (-7, -8)

The point N’ is at (4, -4)

On the x-axis, -7 to 4 is a shift of 11 units to the right.

On the y-axis, -8 to -4 is a shift of 4 units upward.

To find the scale factor, we need to find the change in radius size.

As previously identified, the center of Circle N is (-7, -8). If we draw a vertical line from the center to the edge of the circle, the line will be 2 units long.

As previously identified, the center of Circle N’ is (-4, -4). If we draw a vertical line from the center to the edge of the circle, the line will be 6 units long.

6 is 3 times the amount of 2, meaning the scale factor is 3.

Hope this helps!

On a particular day, the wind added 4 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 4 miles

Agata [3.3K]

(v+4)t=66

t=66/(v+4)

...

(v-4)t=42, using t found above in this equation gives you:

66(v-4)/(v+4)=42 perform indicated multiplication on the left side

(66v-264)/(v+4)=42 multiply both sides by (v+4)

66v-264=42v+168 add 264 to both sides

66v=42v+432 subtract 42v from both sides

24v=432 divide both sides by 24

v=18

So his normal bicycling speed with no wind is 18 mph.

Which form most quickly reveals the vertex?

Jet001 [13]

Answer:

Step-by-step explanation:

A will give you the roots (the x intercepts) just by reading the numbers and doing a small adjustment.

x + 1 = 0

x = - 1 So one of the roots is (-1,0)

x + 5= 0

x = - 5 The other root is (-5,0)

A is not the answer.
