-20 + 4y = -8
-20 – 2y = 4
Find the solution to the system of equations shown above by graphing

The solutions are x=0 and y= -2, if the given equations are and .

Step-by-step explanation:

The given is,

                    ...............................(1)

                     .................................(2)

Step:1

          To find the values of x and y, we subtract the equation (1) and (2)

               ( - )

         Subtraction of the Eqn (1) and (2) becomes,

         Substitute the value of y in Equation (2),

                                                      x = 0

Step:2

         Check for solution,

         Substitute the values of X and y,

                                                    -8 = -8

         Both sides are equal so the values of x = 0 and y = -2 are equal.

Result:

             The solutions are x=0 and y= -2, if the given equations are and .

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
