Which one of the following pairs of terms is composed of like terms? a. 2a, 2b b. –3x, +3y c. abc, cab d. 4mn, 3my

Option C

Step-by-step explanation:

We have to find the pair of terms composed of like terms.

(A) 2a, 2b  Unlike terms

(B) -3x, +3y Unlike terms

(C) abc, cab

    As we know cumulative property of multiplication shows a×(b×c) = (a×b)c

    Therefore, both the terms abc and cab are similar.

(D) 4mn, 3my Unlike terms

Option C is the answer.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
