What is x and y of 2x-4y=10&x+5y=40

Step-by-step explanation:

We are given that

When given these types of equations, we can manipulate them in order to cancel out a variable. Cancelling either the x or y works, choose which one is easier.

In this case, we can multiply the second equation by -2 and easily cancel out the x's

Now we can add the two equations

We can substitute y into the second equation and solve for x

Check:

2(15) - 4(5)

30 - 20 = 10

it works

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 .

0.038
