Answer:
x = 15
y = 10
Step-by-step explanation:
ΔTUR is a 60°-60°-60° triangle because all angles are equal and 180/3 is 60
therefore, the angle adjacent to ∡R is 120 because it forms a straight line (which measures 180 degrees)
that means that angles T and S (which are both 3y°) plus angle R equal 180 so you can set up this equation to find y: 120 +6y = 180
6y = 60
y = 10
Because angles T and S are the same we know that TR and TS are also the same, so RT is 15
ΔTUR is equiangular which means it is also equilateral; so if RT is 15 then UT and UR are 15 also
If UT = 15, we can write this equation: x - 5 = 15 and find that x = 20
2 because for every 5 she gets she gives 2 to her brother and she only got one 5 so its 2

Answer:
(-2,-6)
-2
Step-by-step explanation:
To get the vertex take the number that's in the parathenses with the x and flip it's sign (in this case to a negative) which means we have
-2
this is the x coordinate of the vertex.
Next take the number that's being subtracted (or added) on the outside and leave that as is (-6)
This is the y coordinate
which means we have (-2,-6)
the axis of symmetry is just the x coordinate of the graph
which is -2
Answer:
20.7%
Step-by-step explanation:
3/14.5 = 0.2068
Take 0.2068 and multiply it by 100 to get its percent value which is about 20.7%
$3.00 is 20.7% of $14.50
