Mrs. Stephan took her children to pick out pumpkins. Cater picked out a pumpkin

$35.31

Step-by-step explanation:

(20+13) x (1+0.07) = 35.31

You add the price of both pumpkins together to get the price of the pumpkins before tax. Then you multiply it by (1 + 0.07) because 1 is the regular price plus the sales tax which is a percent that can be converted to decimal to 0.07. You multiply these together and get 35.31

$35.31

Step-by-step explanation:

(20+13) x (1+0.07)

Translation of a units to the right and b units up:

Ta,b → (x + a, y + b)

[This is read as "Translation of positive a along the x axis and poitive b along the y axis" or more simply, "Translation of a units to the right and b units up" as your question states. ]

Reflection across the y- axis  

This is a left to right movement so the sign of your x value is changing but the y value stays the same.  

My-axis  (x, y) → (-x, y)

Reflection across the x-axis

This is an up and down movemet so so the sign of your y is changing but the x value stays the same.  

Mx-axis (x, y) → (x, -y)

rotation of 90 counterclockwise about the origin, point 0  

This is "1" turn, so it moves 1 quadrant, which means your values "flip"  

Ro, 90° (x, y) → (-y, x)

rotation of 180 degrees counterclockwise across the origin, point 0

This is "2" turns,so it moves 2 quadrants which means  x and y will have opposite signs after the move.  

Ro, 90° (x,y)→ (-x, -y)

Rotation of 270 degrees counterclockwise across the origin, point 0

This is "3" turns, so it moves 3 quadrants which means your values will "flip"

Ro, 270° (x,y) → (-y, x)
