Answer:
The missing side length is 36
Step-by-step explanation:
You need to find the ratio of the dilation so if you take corresponding sides, for example, 72 and divide by 8 you get 9. So, if you multiply each side of the triangle XYZ by 9, it should get the length of the sides on triangle ABC.
4 * 9 = 36
Hope this helps! :)
Answer:
C
Step-by-step explanation:
Here, originally, we are told that the point Q has coordinates (-2,1)
Now, its dilated point has the coordinates (-8,4)
what we can observe here is the the shape original polygon was dilated by a factor of 4 to give the image
Now the point R’ is (0,8)
To get the point R , we simply divide each coordinate by 4
Thus, we have (0/4 , 8/4)
This is same as option C
Answer:
200.65
Step-by-step explanation:
147 plus 75% or 110.25 minus 22% or 56.59
Right now, we are given the standard form of the line: ax + by = c
a = 6, b = -3, c = 12
If we use algebra to to change it into its point-slope form, we can easily identify the slope of the equation.
6x - 3y = 12
-3y = 12 - 6x
- 3y = -6x + 12
3y = 6x - 12
3y/3 = (6x - 12)/3
y = 2x - 4
Now the equation is in point-slope form: y = mx + b where m is the slope.
Since m=2, the slope of the line is 2.
A shortcut to find the slope of a line in standard form is m = -a/b
Using the same equation as above, 6x - 3y = 12 a = 6, b = -3
-6/(-3) = 2
The correct answer is 2x/3 -1
