Question 12(Multiple Choice Worth 1 points)

The statement which would best describe the line segments drawn in relation to one another is " They are parallel and congruent " ⇒ 3rd answer

Step-by-step explanation:

In a translation,

  • Every point of the object must be moved in the same direction.
  • Every point of the object must be moved for the same distance.
  • The lines drawn from each point to its image are parallel and congruent.

The rules of translation:

  • If the point (x , y) translated horizontally to the right by h units  then its image is (x + h , y)
  • If the point (x , y) translated horizontally to the left by h units  then its image is (x - h , y)
  • If the point (x , y) translated vertically up by k units  then its image is (x , y + k)
  • If the point (x , y) translated vertically down by k units  then its image is (x , y - k)

∵ Δ JOY is translated using the rule (x, y) → (x + 3, y - 2)

∵ Δ J'O'Y' is its image after translation

- That means each point move 3 units to right and 2 units town

∵ Line segment JJ' joins the vertex J by its image J'

∵ Line segment OO' joins the vertex O by its image O'

- The lines drawn from each point to its image are parallel

   and congruent

∴ JJ' // OO'

∴ JJ' ≅ OO'

The statement which would best describe the line segments drawn in relation to one another is " They are parallel and congruent "

Alex's dog weighs 7 times as much as her cat. Together, the two pets weigh 72 pounds. How much does Alex's dog weigh?
raketka [301]
D=dog's weight
c=cat's weight
d=7c
d+c=72
sub 7c for d
7c+c=72
8c=72
divide both sides by 8
c=9
d=7c
d=7(9)
d=63
dog=63lb
