4/3
Step-by-step explanation:
(4-8)/(2-5) = -4/-3 = 4/3
Answer:
some
Step-by-step explanation:
<h3>Answer:</h3>
F (3x, 3y)
<h3>Explanation:</h3>
Dilation about the origin multiplies each coordinate by the dilation factor. For some coordinates (x, y), dilation by a factor of 3 means the new coordinates are ...
... 3×(x, y) = (3x, 3y)
_____
<em>Comment on the problem</em>
The way the problem is worded, you expect an answer choice that will be specific to the coordinates of point A. There are none.
Instead, the answer choices are generic, corresponding to dilation of a point (x, y) by a factor of 3, translation up and to the right by 3, dilation by a factor of 1/3, and translation down and to the left by 3.
Answer:
calories
Step-by-step explanation:
Given: The racer moves at miles per hour expends energy at a rate of calories per hour.
To find: Energy in calories, required to complete a marathon race miles at this pace.
Solution: We have,
The racer moves at miles per hour.
The racer expends energy at a rate of calories per hour.
So, energy expended while moving miles calories.
Now, energy expended while moving mile calories.
So, energy expended while moving miles calories.
Hence, calories of energy is required to complete a marathon race miles at this pace.
