If a string is 38 millimeters long, how many meters long is it? (1 millimeter = 0.001 meter)
Basile [38]
38 mm to m

38 mm * (0.001 m / 1 mm)
**cancel mm units**
38 * (0.001 m / 1)
0.038 m

the coordinates of a quadrilateral are (5,8), (7,10), (9,12) and (11,14). after a transformation, the sign of the x-coordinate a
BartSMP [9]

Answer:

The quadrilateral is rotated 180° about the origin

Step-by-step explanation:

Lets revise some transformation

- If point (x , y) reflected across the x-axis

∴ Its image is (x , -y)

- If point (x , y) reflected across the y-axis

∴ Its image is (-x , y)

- If point (x , y) reflected across the line y = x

∴ Its image is (y , x)

- If point (x , y) reflected across the line y = -x

∴ Its image is (-y , -x)

- If point (x , y) rotated about the origin by angle 90° anti-clock wise

∴ Its image is (-y , x)

- If point (x , y) rotated about the origin by angle 90° clock wise

∴ Its image is (y , -x)

- If point (x , y) rotated about the origin by angle 180°

∴ Its image is (-x , -y)

* There is no difference between rotating 180° clockwise or

 anti-clockwise around the origin

* In our problem:

- The sign of the x-coordinate and the sign of the y- coordinate

 for each ordered pair have changed

- The image of each point is (-5 , -8) , (-7 , -10) , (-9 , -12) , (-11 , -14)

∴ The quadrilateral is rotated 180° about the origin

Which pair shows equivalent expressions?
Alona [7]

Answer:

Option 3

Step-by-step explanation:

We need to find a pair which shows equivalent expressions.

First equation is

2x+10=-2(x-5)

LHS=2x+10

RHS=-2(x-5)=-2(x)-2(-5)=-2x+10

LHS\neq RHS

Option 1 is incorrect.

Second equation is

-2(x+5)=2x-10

LHS=-2(x+5)=-2(x)-2(5)=-2x-10

RHS=2x-10

LHS\neq RHS

Option 2 is incorrect.

Third equation is

-2x-10=-2(x+5)

LHS=-2x-10

RHS=-2(x+5)=-2(x)-2(5)=-2x-10

LHS=RHS

Option 3 is correct.

Fourth equation is

-2(x–5)=-2X-10​

LHS=-2(x–5)=-2(x)-2(-5)=-2x+10

RHS=-2x-10

LHS\neq RHS

Option 4 is incorrect.

Therefore, the correct option is 3.
