Triangle ABC has vertices at points A(-1,1), B(-4,1) and C(-1,5).
270° rotation about the origin in anti-clockwise direction has the rule:
(x,y)→(y,-x).
Then
- A(-1,1)→A'(1,1);
- B(-4,1)→B'(1,4);
- C(-1,5)→C'(5,1).
Reflection about the x-axis has the rule
(x,y)→(x,-y).
Then
- A'(1,1)→L(1,-1);
- B'(1,4)→M(1,-4);
- C'(5,1)→N(5,-1).
Thus, triangles ABC and LMN are congruent.
Answer: correct option is A.
Just move the invisible decimal to the left until it is less than 10

To find how many degrees Celsius, divide your number in Fahrenheit by 5/9 (or approximately 0.56), then subtract 32. As an example we'll convert 90 degrees Fahrenheit into Celsius.
C = 5/9f - 32
C = 5/9 x 90 -32
C = 50.4 -32
C = 18.4
Answer:
y = 250x + 2175
Step-by-step explanation:
Mr. Jensen month pay = 2175
Commission per policy = 250
Let "x" be the number of policy he sells and "y" is the total paycheck including the commission.
y = 250x + 2175
