Which transformations can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4

)? a 180 (dagree) rotation about the origin a 90 (dagree) counterclockwise rotation about the origin and a translation down 4 units a 90 (dagree) clockwise rotation about the origin and a reflection over the y-axis a reflection over the y-axis and then a 90(dagree) clockwise rotation about the origin

The triangles ABC and A'B'C' are shown in the diagram below. The transformation is a reflection in the line y=-x. This is proved by the fact that the distance between each corner ABC to the mirror line equals to the distance between the mirror line to A'B'C'.

Please help me with this!!!!!!!!!!!!!!
miss Akunina [59]

Answer:

True

Step-by-step explanation:

Its true since it passes the vertical line test. How does the vertical line test work? You put a vertical line through a point and if it has only one point on that specific line it is a function. Note:hope this helps

Is 5 1/25 a rational number
Alla [95]

Answer:

Yes, it is a rational number.

Step-by-step explanation:

Rational numbers are numbers that can be written as a fraction or ratio no matter if it is proper or improper.

Example: Take π for example. Since it goes on forever, it cannot be written a s a fraction or ratio. Therefore it is irrational.

Ending: Therefore, since this can be changed into a fraction, 5 1/5 is rational.

Can i please get some help im pretty desperate and will give brainiest to first answer with some steps, just try your best pleas
Citrus2011 [14]

Answer:

To calculate the vertex you can use the vertex form ( i searched about the vertex and found it) but i don't know how to use it so i used another method.

The vertex is where the function inverts (y values) so it is going to be or a maximum or a minimum of the function. To calculate the min/max you derivate the function and then equal it to zero.

1) y  = -3x^2 -12x -10

the derivative of y is y' = -6x -12 = -6(x+2)

y'=0 <=>  -6(x+2) = 0 <=> x+2=0 <=> x=-2

y(-2) = -3(-2)^2 -12*(-2) -10 = 2

So the vertex is the point (-2,2) .

Because the slope of the equation is negative that means that the vertex is going to be the maximum , so the maximum is (-2,2) .

To find another 4 points you just have to pick values of x and replace them in the equation y  = -3x^2 -12x -10  to find y.

2) y = -2x^2 -12x -16

Do the same thing we did in point 1

y'= -4x-12 = -4(x+3)

y'=0 <=>  -4(x+3) = 0 <=> x+3=0 <=> x=-3

y(-3) = -2(-3)^2 -12*(-3) -16 = 2

So the vertex is the point (-3,2) .
