Answer: 54 mph
Step-by-step explanation:
d-the distance
s+9 - the speed to the conference
d=6*(s+9)
s- is the speed on the way back home
d=7*s
so 6*(s+9)=7*s
6s+54=7s
-6s -6s
54= 7s-6s
s=54 mph
She has a total of 170 cubes
170/10=17 trains
The common rule is (x - 1, y + 3) can be used to describe the translation.
Step-by-step explanation:
Step 1:
The point J (-3, -4) becomes (-4, -1).
In order to write the rule for translation from J to , we subtract the x coordinate of J from and subtract the y coordinate of J from .
The x coordinate
The y coordinate
Step 2:
So from the calculations, we get that the x coordinate is subtracted by 1 i.e. and the y coordinate is increased by 3 i.e. .
So the common rule is (x - 1, y + 3).
Answer:
Option B Yes by AAA
Step-by-step explanation:
we know that
If the two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
so
substitute the values and verify
simplify
-------> is true
therefore
The triangles are similar by AAA------> the three angles are congruent
