Find the image of U'( -8 , 1) after a translation along < 2 , 0 > and a reflection in the x axis
Lana71 [14]

Given:

The point is U'(-8,1).

It is translated along <2,0> and reflected across the x-axis.

To find:

The image of U'.

Solution:

The given point is U'(-8,1).

It is translated along <2,0> . So, the rule of translation is:

(x,y)\to (x+2,y+0)

U'(-8,1)\to U_1(-8+2,1+0)

U'(-8,1)\to U_1(-6,1)

Then, it is reflected across the x-axis. So, the rule of reflection is:

(x,y)\to (x,-y)

U_1(-6,1)\to U''(-6,-1)

The image of U'( -8 , 1) is U''(-6,-1).

Therefore, the correct option is A.

For binomials of the form (x - y) ^ n explain how to determine the sign of a term without writing out the entire expansion
Mnenie [13.5K]

Answer:

When raising an expression of that format to any power, after grouping like terms, you'll always find that the odd numbered terms are positive, and the even numbered terms are negative.

For example:

(x - y)² = x² − 2xy + y²

(x - y)³ = x³ − 3x²y + 3xy² − y³

(x - y)⁴ =x⁴ − 4x³y + 6x²y² − 4xy³ + y⁴

etc.
