Answer:

R' is ( 7 , -4 )

Step-by-step explanation:

( 3 , -4 ) reflected over x = 5

Since the line x = 5 is vertical we'll need to add to the x coordinate of point R.

( 3 , -4 ) is 2 units away from x = 5 so we'll need to add 2 units to 5 and we get

( 7 , -4 ) is R'

Answer:

(7,-4)

if x=5 then imagine a new vertical line on 5

(3,-4) is two spaces left of 5, so to reflect if you would move it two spaces to the right of 5

Answer:

1/5

Step-by-step explanation:

1 kg = 1000 g so your ratio is ...

$\dfrac{0.0064\text{ kg}}{32\text{ g}}=\dfrac{0.0064\cdot1000\text{ g}}{32\text{ g}}=\dfrac{6.4}{32}=\boxed{\dfrac{1}{5}}$

How do you know whether to add or subtract when using the distributive property to multiply?

bixtya [17]

Distributive property is characterized by the use of parenthesis, wherein you distribute the outside number to each term inside the parenthesis by multiplication. You'll just have to copy the operation inside the parenthesis as it is, whether addition or subtraction. For example,

3(10+4-3) = 3(10) + 3(4) - 3(3) = 33

Answer:

Point R is at (-40,30), a distance of 60 units from point Q

Step-by-step explanation:

Explanation

we will use below conditions

Type of transformation change to co-ordinate point

vertical translation up 'd' units (x, y) changes to (x, y +d)
vertical translation down 'd' units (x, y) changes to (x, y-d)
horizontal translation left 'c' units (x, y) changes to (x- c, y)

4. horizontal translation right 'c' units (x, y) changes to (x+ c , y)

now Given data is P( 20,-30) and in the graph Q(-40,-30)

Step1:-

Now we have to find 'R' point

Given data the point "R' is vertically above point Q so the point "Q' is moves vertically up with '60' units

now we will use the condition (1)

Q(-40,-30) is vertical translation up '60' units now changes the co-ordinate point is (-40 , -30+60)

The correct translation and The point R( -40 , 30)

Step2:-

Again in the given data "R" is at the same distance from point Q as point P is from point Q.

so given P point is (20 , -30)

now we translation 'P' also

vertically translation up at a distance '60' units and changes the new co-ordinate (20 , -30+60) that is (20,30) [ use above condition is (1)]

and again horizontal translation left '60' now changes (20 - 60 ,30)[ use condition (3)]

There fore the new co-ordinate is R( -40 , 30)

Final answer:-

Point R is at (−40, 30), a distance of 60 units from point Q
