The image point of (-4,8) after a translation right 3 units and down 3 units is (-1, 5)

<h3>What is a transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformations are<em> reflection, translation, rotation and dilation.</em>

Rigid transformation are transformation that preserve the shape and size hence producing congruent figures such as translation, reflection and rotation.

The image point of (-4,8) after a translation right 3 units and down 3 units is (-1, 5)

a rectangular wall with a length of 10x and width of 20 x has a rectangular doorway with a length of 5x and a width of 2x. What

Shtirlitz [24]

Answer:

∴ The the surface area of the wall is $190x^{2} \ square\ unit$ .

Step-by-step explanation:

Given that,

The length of rectangular wall is $10x$ .

The width of rectangular wall is $20x.$

The length of doorway is $5x.$

The width of doorway is $2x.$

and, we have to find the surface area of rectangular wall.

Now,

The length of rectangular wall is $10x$ .

The width of rectangular wall is $20x.$

∴ Total surface area of a rectangular wall $= Length\ of\ wall\times Width\ of\ wall$

$= 10x\times 20x$

$=$ $200x^{2} \ square\ unit$

Total surface area of a rectangular wall is $200x^{2} \ square\ unit$ .

Again, The length of doorway is $5x.$

The width of doorway is $2x.$

∴Total surface area of doorway $=Lenght\ of\ doorway\times Width\ of\ doorway$

$=5x\times 2x$

$=10x^{2} \ square\ unit$

Total surface area of doorway is $10x^{2} \ square\ unit$ .

∴The remaining surface area of a rectangular wall is $=$ $200x^{2} -10x^{2}$

$=190x^{2} \ square\ unit$

∴ The the surface area of the wall is $190x^{2} \ square\ unit$ .

How do I do 1/2 divided by -2/5 + -1/4

anastassius [24]

IF -2/5 + -1/4 IS IN PARENTHESES:

skip this part if its not

(1/2) / (-2/5 - 1/4)

(-2/5 - 1/4) is equivalent to (-8/20 - 5/20) = -13/20

substitute -13/20 for (-2/5 - 1/4)

1/2 / -13/20

remember that division is the inverse of multiplication, so if we flip the second fraction, we can change the division sign to multiplication (when doing this, never flip the first fraction, you will not get the right answer)

1/2 * -20/13

simplify -20/2 to get -10

1 * -10/13 = <u>-10/13</u>

IF -2/5 + -1/4 IS NOT IN PARENTHESES:

1/2 / -2/5 +-1/4

PEMDAS : multiplication/division comes before addition / subtraction

1/2 / -2/5 = (apply the flip rule : read the chunk of text above if you don't know what it is) 1/2 * -5/2 = -5/4

subtract 1/4 form -5/4 now

-5/4 - 1/4 = -6/4

simplify

= <u>-3/2</u>

PLEASE HELP IM DESPERATE<br><br> ALL I NEED IS FOR SOMEONE TO ANSWER NUMBERS 7, 8, AND 9

andrezito [222]

Answer:

The answer to 9 is below

Step-by-step explanation:

2(L + W) = P

2(W + 5a - b) = 16a + 2b

2(W + 5a - b) = 2(8a + b)

W + 5a - b = 8a + b

W = 3a + 2b
