So, you know that the fraction in front of the x is the slope, right?
She travels 1800 meters because the bus ride is moot point and she walks home twice once for lunch and once to come home for night and once back to work, so three times 600 meters is 1800 meters
Answer:
A∩B={7,9}
Option A is correct option.
Step-by-step explanation:
We are given:
A = {3, 5, 7, 9} and B = {1, 2, 4, 6, 7, 9}
and we need to find A intersects with B i.e. A∩B
We find A intersects with B, we will consider only those terms that are common in both A and B
So,
A∩B= {3, 5, 7, 9} ∩ {1, 2, 4, 6, 7, 9}
As 7 and 9 are only common in both A an B
A∩B={7,9}
So, we get: A∩B={7,9}
Option A is correct option.
Number - x
![2 |x - 3| = 3(x + 9) \\ 2 |x - 3| = 3x + 27 \\ |x - 3 | = 1.5x + 13.5](https://tex.z-dn.net/?f=2%20%7Cx%20%20-%203%7C%20%20%3D%203%28x%20%2B%209%29%20%5C%5C%202%20%7Cx%20-%203%7C%20%20%3D%203x%20%2B%2027%20%5C%5C%20%20%7Cx%20-%203%20%7C%20%20%3D%201.5x%20%2B%2013.5)
2 Answer once when it minus and one when it plus
if plus
![x - 3 = 1.5x +13.5 \\ - 0.5x = 16.5 \\ x = - 33](https://tex.z-dn.net/?f=%20x%20-%203%20%3D%201.5x%20%2B13.5%20%5C%5C%20-%20%200.5x%20%3D%20%2016.5%20%5C%5C%20x%20%3D%20%20-%2033)
if minus
![- (x - 3) = 1.5x + 13.5 \\ - 2.5x = 10.5 \\ x = - 4.2](https://tex.z-dn.net/?f=%20-%20%28x%20-%203%29%20%3D%201.5x%20%2B%2013.5%20%5C%5C%20%20-%202.5x%20%3D%2010.5%20%5C%5C%20x%20%3D%20%20-%204.2)
these are the possible numbers
Answer:
The two triangles are related by angles, so the triangles are similar but not proven to be congruent.
Step-by-step explanation:
Because the triangles have the same angles, they are congruent. The definition of congruence is if you take a shape and scale it up or down (or keep it the same) therefore, they are congruent.
Hope this helped, have a nice day
EDIT: I screwed up, I thought it was supposed to be similar. These triangles are SIMILAR not congruent. The actual answer is they are related by AAA similarity but they are similar, but they are not proven to be congruent. Hope this clears it up, and sorry.
