Two variable equation LET x=0 x-2y=4 what is the value of y?

Solve for the missing variable: LET y=0: x-2y=4 what is the value of x?

Step-by-step explanation:

(i) Let x = 0 and x-2y=4

Put x = 0 in x-2y=4

0-2y=4

-2y=4

y=-2

If x = 0, the value of y is -2.

(ii) Let y=0 and x-2y=4

Put y = 0 in x-2y=4

x-2(0)=4

x=4

If y = 0, the value of x is 4.

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
