Answer:
It is C
Step-by-step explanation:
7/2 is 3.5. We can see that if we multiply the y value of 2 for d, it becomes 7, which is shown there. All other choices do not make sense.
To reflect in the line y = -x + 6, we translate everything down 6 first.
This will make it seem like we are reflecting in the line y = -x
(x,y) → (x, y-6)
Then, to reflect in the line y = -x, we switch the x- and y-coordinates and then make them negative
(x,y) → (-(y-6), -x)
Then we move everything back up again
(x,y) → (-(y-6), -x + 6)
I will present to you an example. Reflect the point (-4, 8) in the line y = -x + 6.
(-4,8) → (-(8-6), -(-4) + 6) → (-2, 10)
You should graph this out to confirm with the reflection line.
Answer:
6:9:15
Step-by-step explanation:
multiply each number in the first ratio by three. They multiplied 3 times three to get 9, so you have to do that to each number to make it a ratio.
A ratio is like an equivalent fraction. It all has to be proportionate to the other fraction.
Examples:
4:3 is equal to 8:6
16:6 is equal to 32:12
Answer:
60 Minutes
Step-by-step explanation:
The formula d = rt represent distance equal to rate * time
As were are looking for time, we can plug in d and r for 14 = 14t
With this, we can see the t = 1, though this is still in hours. Convert 1 hour to minutes, and we'll be given 60 minutes which is our answer, C
The answer is 149 because it is 180-31
