Just substitute the value x into the equation y=2x
y = 2x
y = 2(-1)
y = -2
use the same method for the rest
Shape A is congruent to shape D because a 180° rotation about the origin and then a translation 2 units right maps shape A onto it.
Shape B is congruent to shape E because a 90° clockwise rotation about the origin and then a translation 1 unit left maps shape B onto it.
Answer: (x,y)---->(4x,4y)
Step-by-step explanation:
1. By definition, dilation is as a transformation in which the figure is enlarged or reduced.
2. For dilation you have:
- A scale factor, that determines how much the figure will be reduced or enlarged.
- The center of dilation, which is defined a a fixed point in the plane.
3. If the figure is dilated with a scale factor of 4 and the center of dilation at the origin, you must multiply each coordinate of the original figure by 4, then. Then, the rule is:
(x,y)---->(4x,4y)
Answer:
Okay to help with number 3 and 4 and 5
Step-by-step explanation:
g + 15 ≤ 3
step 1. subtract 15 from both sides
g ≤ -12
x/4 ≥ -4
Step 1. multiply 4 on both sides
x ≥ -16
5. -9x > -90
Step 1. divide -9 on both side (remember to switch the inequality sign)
x < 10
