Answer:
Reflection: A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
Dialation: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)
Step-by-step explanation:
A(−5,3),B(−2,3),C(−2,1),D(−5,1)
To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:
A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
To dialate by a scale factor of 2 you multiple everything by 2 and you should get: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)

Answer:
10 +2x
Step-by-step explanation:
Put the given values into the perimeter formula and simplify.
P = 2(L+W)
P = 2(5 + x)
P = 10 +2x . . . . the perimeter of the rectangle in units
Answer:
see attached graph
Step-by-step explanation:
Given equation: 
Standard form of a quadratic equation: 
where 
is the y-intercept
If 
then the parabola opens upwards.
If 
then the parabola opens downwards.
Therefore, the y-intercept of the graph is (0, 3)
To find the x-intercepts, factor the equation:
Therefore, the x-intercepts of the graph are (3, 0) and (1, 0)
To determine the vertex, differentiate the equation:
Set to zero and solve for x:
Substitute 
into the original equation and solve for y:
Therefore, the vertex (or turning point) is at (2, -1)
