Which pairs are like terms in the expression below? select all that apply.

25y + 15x – 0.2y – 6 + (–2)
a. 2/5y and 1/5x
b. 2/5y and –0.2y
c. 1/5x and –0.2y
d. –0.2y and 2
e. –6 and –2

Step-by-step explanation:

like terms have exactly the same variablealso, numbers with no variables are like terms too.

2/5y + 15x - 0.2y - 6 + (-2)

like terms are :

2/5y and -0.2ybecause they have the exact same variable (letter)

-6 and -2numbers with no variables are like terms

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
