Answer:
Step-by-step explanation:
If x is an odd integer, the next greater odd integer is x+2. The product is said to be 63, so the equation is ...
x(x +2) = 63
__
The equation can be rewritten as ...
(x +1)² = 64
x = -1 ±√64 = -1 ±8
The positive solution is x=7, so the positive set of integers is {7, 9}.
The negative solution is x=-9, so the negative set of integers is {-9, -7}.
Answer:
I think the correct answer is -1.
The "Pre Image" is the image that we started with, so the pink triangle.
The "Image" is the image that we ended with, so the blue triangle.
To determine how far we went from the pre image to the image, we can focus on one point, let's say point "P".
The pre image coordinates for point "P" are 2, 3.
The image coordinates for point "P'" are -1, 0.
To get from x value 2 to x value -3, we subtracted 3.
To get from y value 3 to y value 0, we subtracted 3.
So, our rule for this translation would be A, (x, y) ----> (x-3, y-3).
Answer:
The train appears to go the same distance each minute
9mins
The cost for each person appears to be the same
Step-by-step explanation:
So for the first qu you basically want to find the distance the train travels each minute, so for
3mins : 9km
therefore
1min : 3km
basically divide 9 by 3
then the train travels 27km, how long does it take?
if 3km = 1min
then 27/3 = 9
so it takes the train 9 minutes
Then for the second qu you'll do the same thing
2ppl : $16
so one person : 16/2
so 1 person costs $8
so for 8 ppl you multiply 8 by 10
8ppl : $80
hope this helps:))))
