Answer:

The set of rigid motions could be used to show that triangle ABC is congruent to triangle DEF is " a horizontal translation and a vertical translation" ⇒ D

Step-by-step explanation:

Horizontal translation means move the object right or left
Vertical translation means move the object up or down
Translation horizontally or vertically not change the direction of the object or its size, then the image is congruent to the original object
Rotation and reflection change the direction of the object but do not change its size

∵ Δ DEF has the same direction as Δ ABC

∵ Δ DEF is congruent to Δ ABC

∴ The translation is using

∵ Δ DEF is right and below to Δ ABC

∴ There are horizontal and vertical translation

The set of rigid motions could be used to show that triangle ABC is congruent to triangle DEF is " a horizontal translation and a vertical translation"

Problem 3: Let x = price of bag of pretzels Let y = price of box of granola bars
We have Lesley's purchase: 4x+2y=13.50
And Landon's: 1x+5y=17.55
We can use the elimination method. Let's negate Landon's purchase by multiplying by -1. -1x-5y=-17.55
We add this four times to Lesley's purchase to eliminate the x variable.
2y-20y=13.50-70.2
-18y=-56.7
y = $3.15 = Price of box of granola bars

Plug back into Landon's purchase to solve for pretzels.
x+5*3.15=17.55
x+15.75=17.55
x = $1.80 = price of bag of pretzels

Problem 4.
Let w = number of wood bats sold
Let m = number of metal bats sold

From sales information we have: w + m = 23
24w+30m=606
Substitution works well here. Solve for w in the first equation, w = 23 - m, and plug this into the second.
24*(23-m)+30m=606
552-24m+30m=606
6m=54
m=9 = number of metal bats sold
Therefore since w = 23-m, w = 23-9 = 14. 14 wooden bats were sold.
