Annie is creating a stencil for her artwork using a coordinate plane. the beginning of the left edge of the stencil falls at (1, −1). she wants to align an important detail on the left edge of her stencil at (3, 0). she knows this is 1: 3 of the way to where she wants the end of the stencil. where is the end of the stencil located?

The end of the stencil is located at, (9 , 3)

Step-by-step explanation:

Let, the end of the Stencil is located at (x ,y) .

According to the question,

The point (3 , 0) cuts the straight line segment joining (1 , -1) and (x , y) in the ratio 1 : 3 .

So,

⇒x  + 3 = 12

⇒x = 9 (1)

Again,

⇒ y = 3 (2)

So, the end of the stencil is located at, (9, 3)

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

just sum

10 + 10 = 20
