When dilation is about the origin, as it is here in every case, the image point coordinates are the original (pre-image) coordinates multiplied by the scale factor.
1. Multiply every coordinate value by 5:
... W' = (-5, 10), X' = (-15, -5), Y' = (25, -5), Z' = (15, 10)
2. Multiply every coordinate value by 1/3:
... A' = (-2, 5), B' = (0, 5/3), C' = (1, 10/3)
3. A' = (2, 8), B' = (6, 2), C' = (2, 2)
4. The image coordinates are 5 times the original coordinates, so ...
... the scale factor of the dilation is 5.
Answer:
C
Step-by-step explanation:
C is the only function that have a consistent decrease while A is a trigonometric function, B is a non linear function, D is an exponential function
Answer:
(4, 3)
Step-by-step explanation:
Since the x is by itself in the first equation already, we can solve for y in the next equation and substitute for x.
(y+1)+2y=10
3y+1=10
<u>-1 -1</u>
3y=9
y=3
Next, we need to find x. To do this, we need to substitute y with 3 in one of the equations.
x=(3)+1
x=4
The ordered pair is finally (4, 3).
Hope this helps!! I literally just learned this today...have a great day ❤
Answer:
5 and 6
Step-by-step explanation:
The square root of 25 is 5 and the square root of 36 is 6. 33 falls between those
