Answer:

A and B

Step-by-step explanation:

For A, y=2 is the axis of vertical symmetry, meaning a reflection would map the shape onto itself.

For B, x=3 is the axis of horizontal symmetry, meaning a reflection would map the shape onto itself.

For C, a rotation of 90 degrees would make the shape taller vertically and shorter horizontally, therefore it would be wrong.

For D, a translation two units down would move all points down, even though some would need to go up, therefore it would be wrong.

(x+2y = 10 16y=-3x+30

Harlamova29_29 [7]

Answer:

x = 10, y = 0

Step-by-step explanation:

x + 2y = 10

x = 10 - 2y (Bring the 2y to the right)

16y = -3x + 30

16y = -3(10 - 2y) + 30 (Substitute x to 10 - 2y)

16y = -30 + 6y + 30 (Expand brackets)

10y = 0 (Bring y to the left)

y = 0

x = 10 - 2(0) (Substitute y = 0)

x = 10

x = 10, y = 0

raketka [301]

Answer: 30 trees

Step-by-step explanation:

Elizabeth has 330 citrus trees and 180 palm trees

The largest number of trees that she can have in a row will base on the highest common factor between the two number of trees

330 = 2 × 3 × 5 × 11

180 = 2 × 2 × 3 × 3 × 5

HCF = 2 × 3 × 5

HCF = 30

The largest number of trees that she can have in a row is 30 trees.
