Answer:
3
Step-by-step explanation:
substitute x = 4 , y = 6 into the expression
y - (5 - (x - y))
= 6 - (5 - (6 - 4))
= 6 - (5 - 2))
= 6 - 3
= 3
The answer is b
The perimeter of a rectangle is 2(l + w) so in this case, it is 2(15 + 9) and that is equal to 48. But so at c and d. So u need to multiply the width by 2 (9*2=18) and then you’ll see that 18-3=15. And therefore, the length is -5 and the width is 9
Answer:
No; the slopes of segment EF and segment DF are not opposite reciprocals.
Step-by-step explanation:
The slope between two points O(e, f) and X (g,h) is given as:
The slopes of segment EF and segment DF are given below:
For triangle DEF to be a right triangle, DF and EF are supposed to be perpendicular to each other. Two line are said to be perpendicular if the product of their slope is -1, i.e the slope of one line is the negative reciprocal (opposite reciprocal) of the other line.
Since the slope of DF and EF are not opposite reciprocals, ΔDEF is not a right triangle.
y = 3 is the line of reflection
Under a reflection in a line, corresponding points of the original and it's image should be equidistant from the line of reflection
y = 3 is the horizontal line passing through all the points with a y-coordinate of 3
A is 1 unit above and A' is 1 unit below the line
B is 3 units above and B' is 3 units below
C is 1 unit below and C' is 1 unit above
D is 1 unit below and D' is 1 unit above
The vertices of the figure and the image are all equidistant from y = 3
