Dox needs to solve the system of equations below 4x + 5y = 7
2x - 3y = 9

He decides to use the elimination method to cancel out the x terms in order to first solve for y. Dox uses the following steps:

Step 1: 4x + 5y = 7
-2(2x) - 3y = 9

Step 2: 4x + 5y = 7
-4x - 3y = 9

Step 3: 2y = 16

Step 4: y = 8
Did Dox use the correct steps to solve for y?

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 .

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
