Step-by-step explanation:
5 units up would be written as: 
.
3 units to the left would be 
.
The rule that describes the translation of 5 units up and 3 units to the left would be:
Answer:
a = 4, b = 
Step-by-step explanation:
Use any ordered pairs of points from the table.
Substitute into the equation and solve for a and b, that is
Using (0, 4), then
4 = a
= a
Hence a = 4
Using (2, 1), then
1 = 4
( divide both sides by 4 )
b² = 
( take the square root of both sides )
b =
Equation is
y = 4
If the spinner is spun three times, there are three possibilities for each spin, so there are 3*3*3=27 possible outcomes. Note that the letters on the spinner are extraneous information (i.e. you don't need to know what the letters are to solve the problem).
