Determine the coordinates of the pre-image?

Mathematics
1 answer:
d1i1m1o1n [39]3 years ago
7 0

Just find the coordinates and divide the x and y coordinates by the scale factor.

I'll do A.

(4,3)

Divide 4 by 0.5 and 3 by 0.5.

4/0.5=2

3/0.5=1.5

So the original coordinate for A is (2,1.5).

Hope it helps

3. What % of 100 is 13?
Sedbober [7]

Answer:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 13 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 13 is 100%, so we can write it down as 13=100%.

4. We know, that x is 100% of the output value, so we can write it down as x=100%.

5. Now we have two simple equations:

1) 13=100%

2) x=100%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

13/x=100%/100%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 100% of 13

13/x=100/100

(13/x)*x=(100/100)*x       - we multiply both sides of the equation by x

13=1*x       - we divide both sides of the equation by (1) to get x

13/1=x

13=x

x=13

now we have:

100% of 13=13
