First you should plot the points and connect them so you can see the triangle.
Then you need to find the slope of each line segment. Then you need to get the slope that would be perpendicular to each individual slope.
Then you got to the OPPOSITE vertex of each line segment, and use the perpendicular slope from that vertex to draw a line, then you will see that all 3 of them intersect at (5,-1)
Answer:
170
Step-by-step explanation:
First, find the area of the rectangles. It's length is 10, and the width is 5. Multiply them to get an area of 50. Since there are 3 congruent rectangles, multiply that by 3. Then find the area of the triangle. It's height is 4, and the base is 5. Multiply and divide by 2, giving you 10. Since there is a congruent triangle add 10 again, as well as the area of the 3 rectangles.
50+50+50+10+10 = 170
Answer:
Y must be negative
Step-by-step explanation:
Use this equation as an example: 5 + -7 = negative
If you add both of them you end up with -2
-2 is a negative integer
The reflection of any point across the x axis is the symmetric of this point, having x axis as axe of symmetry
Let :
A(1,3) its symmetric vs. x axis is A'(1,-3)
B(-1,5) its symmetric vs. x axis is B'(-1,-5)
C(-3,-3) its symmetric vs. x axis is C'(-3,3)
D(-4,-4) its symmetric vs. x axis is D'(-4,4)
Symmetry vs. the x axis keeps abscises the same & change just the sign of y value
