![T^{-2}:(x,y)](https://tex.z-dn.net/?f=T%5E%7B-2%7D%3A%28x%2Cy%29)
means doing the inverse transformation twice.
The forward transformation is given as
![T:(x+3,y+1)](https://tex.z-dn.net/?f=T%3A%28x%2B3%2Cy%2B1%29)
so the inverse transformation is
![T^{-1}:(x-3,y-1)](https://tex.z-dn.net/?f=T%5E%7B-1%7D%3A%28x-3%2Cy-1%29)
and
Answer:
answer of 13) Lenght of one edge of this cube = 3cm
answer of 14) The area of BCE = 25 cm^2
Step-by-step explanation:
Any cube has six identical sides.
Let one side have an area of A.
Let the lenght of one cubic side be L.
L * L = A
So this results in L = SQRT (A)
All six A combined add up to 54 cm^2.
Then 6 * A = 54
A = 54/6 = 9 cm^2
L = SQRT (9)
Lenght of one edge of this cube = 3cm
To find the area of BCE you can simply subtract the area of CDE from the biggest triangle BDE.
2 * BDE = {5+4) * 10
so BDE = 45
2 * CDE = 4 * 10
so CDE = 20
BCE = BDE - CDE
BCE = 45 - 20
The area of BCE = 25 cm^2

Answer:
Daniel = 207 | Brandon = 196.2
Step-by-step explanation:
Brandon will reach the taco truck first.
• Daniel's time can be found by using the expression 327.6/3 + 489/5, which is 207 seconds.
• Brandon's time can be found by using the expression
327.6^+489^2/3 [Sqaured]
The equation is
(y-2)/(x-(-1))=-6
y-2=-6x-6
y=-6x-4
