For the transformation t , write the t
t: (x, y)-> (5x,5y)

Step-by-step explanation:

T:  x' = 5x

    y' = 5y

calculate x , y :

x = 1/5x'

y = 1/5 y'

T-1 : x' = 1/5x

      y' = 1/5y

T-1 : (x;y)→ ( 1/5x  ; 1/5y )

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
