Hi there!
The change of y-values is
- 15 - 22 = - 37
The change of x-values is
7 - - 8 = 7 + 8 = 15
Therefore, the slope of this line is
Answer:
6 1/9 hours
Step-by-step explanation:
10 3/9 - 4 2/9 = 6 1/9
Answer: The first number is 4
Explanation: Since the sum of the two numbers is ten, x + y = 10
Also, since the difference of the two numbers is two, then x - y = 2
Since x - y = 2, another way to write that is x = y + 2 and since x is exactly the same as y + 2, we can plug in "y + 2" in place of x in the first equation (x + y = 10) to get (y + 2) + y = 10. Then we solve this equation by combining like-terms.
2y + 2 = 10
2y = 8
y = 4
Since x = y + 2, x = 4 + 2 or x = 6
I hope this helped you!
Answer: Dilation
Step-by-step explanation:
Since, in isometry the shape and size does not change after transformation.
In a reflection, rotation and translation the shape and size of a figure is preserved therefore they are isometry while in dilation the size of the figure changes by a scale factor.
( However we get the similar figures after dilation but they are not congruent.)
Therefore, we can not consider dilation an isometry.
The legs are 12 cm each, so the hypotenuse is
√(144+144)=12√2
