Triangle a is the pre-image in a translation, and triangle b is the image, as shown below.

how was triangle a translated?
four units left
four units right
six units left
six units right

six units right

Step-by-step explanation:

we know that

The point in the triangle A is translated to the point in the triangle B

so

The rule of the translation is equal to

That means-------> The translation is six units to the right

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
