The rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is Rotation 0° to 90° and reflection about the x-axis.
<h3>What is the transformations rule that was used here?</h3>
A transformation is a rule that is used to manipulate the position of a point of geometric figure.
Analyzing the figure, rotation of ΔJKL through the angle 90 degrees in a counter-clockwise direction gives us ΔJ'K'L' .
ΔJ"K"L" is been gotten also using ΔJ'K'L' through the refraction of ΔJ'K'L' across the x-axis.
In this case, rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is Rotation 0° to 90° and reflection about the x-axis.

Answer:
5 5/7
Step-by-step explanation:
Convert it to fractions:
30/7 and 4/3
Now multiply.
120/21
Simplify it:
5 5/7
If the number only has 2 digits, it could only be 91, because since the tens digit is 8 more than the ones digit, the tens digit is greater than or equal to 8. it cannot be 10 or more, because that would make the number over 100, leaving only 8 and 9. If the tens digit is 8, the ones digit is zero, and since it cannot be zero, then the tens digit must be 9, leaving the ones digit to be 1. So, the final answer is 91.
Answer:
x = 2
y = -5
Step-by-step explanation:
2x - y = 9
y = x - 7
2x - y = 9
2x - (x - 7) = 9
2x - x + 7 = 9
x + 7 = 9
x = 2
y = x - 7
y = 2 - 7
y = -5
Answer:
-8
Step-by-step explanation:
Since you can't take 18 away from 10, you get negative eight. You can take up to 10 away from 18 so this is how you end up with 8 left over.
