-- Reflecting across the x-axis makes all the x-coordinates the negative of
what they were before the reflection. The y-coordinates don't change.
-- Translating 2 units up makes all the y-coordinates 2 greater than
they were before the translation. The x-coordinates don't change.
You didn't give us a list of new coordinates, so there's nothing
to match with.
The points have the same x-coordinate, so they lie on a horizontal line. The distance between them is the difference between their y-coordinates.
2.5 - 1.4 = 1.1
The distance between the two points is 1.1
Answer:
2/3
Step-by-step explanation:
so the inverse takes us from the range to the domain... they tell us that f(4) goes to 5.. so if we were to take the inverse f
(5) it takes us back to 4... and the slope at 4 or the derivative was 2/3 so that's what we get for f
'(5) :)
Answer:
<h3>Toni can type words in 3 minutes is 270 words</h3>
Step-by-step explanation:
Given that the double number line shows that Toni can type 180 words in 2 minutes.
<h3>To find how many words can Toni type in 3 minutes:</h3>
From the given Toni can type 180 words in 2 minutes,
⇒ Toni can type 
<h3>∴ 90 words per minute </h3>
For Toni would be able to type words in 3 minutes is
<h3>∴ 270 words per minute.</h3><h3>∴ Toni can type words in 3 minutes is 270 words.</h3>
She will need 12 seconds because -20•12=-240
