Answer:
point A' is (5, 9)
Step-by-step explanation:
A (-2,-5) is a glide reflection wear the translation is (x,y) is x+7,y and the line of reflection is y=2
A is (-2,-5)
a glide reflection wear the translation is (x,y) is (x+7,y)
7 is added with x, so add 7 with x value -2 on A(-2,-5)
(-2+7, -5)
(5,-5)
Reflection is y=2
So we need to find the difference of y values of point (5,-5) and y = 2
2-(-5) = 7
So we move 7 units up from y = 2. y=2+7 = 9
x value remains the same x=5
Hence point A' is (5, 9)
A) the perimeter of a triangle is the bottom plus the left slanty side plus the right slanty side, but you need the bottom in ft so that would be 6 ft. the perimeter is 13 ft
b) 1 yard
Answer:
The y-value is -20
Step-by-step explanation:
So let's solve this by Elimination method;
-2(4x + 5y = -12)
4(2x + 3y = -16)
Let's Distribute;
-8x - 10y = 24
8x + 12y = -64
So x cancels out because -8 + 8 = 0
-10y + 12y = 2y
24 - 64 = -40
2y = -40
Divide both sides by 2;
y = -20
Now lets plug in y to find the value of x;
4x + 5(-20) = -12
4x - 100 = -12
Add 100 to both sides;
4x = 88
Divide both sides by 4;
x = 22
The rate of change is 110 percent.
