Answer:
(x, y) → (2x - 2, 2y - 1)
Step-by-step explanation:
The original length from Point E to Point G was 2. The length after the figure was transformed is 4. This means that the value of x was multiplied by 2 because 2(the original value) multiplied by 2 equals 4(the new value.)
After the x value is doubled, Point E is found at x = 0 when the transformed Point E is at x = -2. This tells us that the x value has to decrease by 2 after it is doubled.
The original length from Point F to Point H was 4. The length after the figure was transformed is 8. This means that the y value doubled in value, which is the same as saying it was multiplied by 2.
After you double the y value, Point F is found at y = 9, but the fully transformed figure's Point F is found at y = 8. This means that after the y value is doubled it should decrease by 1.
I hope this helps, and let me know if you have any other questions :)
A=l*w
161=14w
161/14=w
11.5cm is the width
If the perimeter of a circle is d*pi, then you would do ((30*3.14)-(20*3.14))/2 to find the perimeter.
30*3.14=94.2
20*3.14=62.8
94.2-62.8=31.4
31.4/2=15.7 cm
(y-14)(y+14). You just square root 196
Gradient is basically the same as slope in this instance. so the answer would be positive 4.
