Triangle END is reflected across the line y = x using the rule (x, y) -- (), x) to create triangle E'N'D' If a line segment is drawn from point E to point E, which statement would best describe the line segment drawn in relation to the line y = x?
O Both are congruent to each other
O Both create diameters of concentric circles
They are parallel
They are perpendicular

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
