Combine any like terms 2x + 3y -6x -8y + 10

Step-by-step explanation:

-4x - 5y + 10

hope this helps

-24x + 4y

Step-by-step explanation:

first step is to expand -4 is used to multiply 5x + 3y

first know that - × + = -

                       - × - = +

-4 × 5x = -20x

-4 × 3y = -12y

-2 × 2x = -4x

-2 × -8y = 16y

-4(5x + 3y)-2(2x - 8y) = -20x - 12y - 4x + 16y

we can rearrange this by collecting like terms close to each other

-20x - 4x - 12y + 16y = -24x + 4y

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
