Which expressions are equivalent to -6 +49 +(-6q)?
Choose all answers that apply:

C, none of them are equivalent

BECAUSE

For A, the -4q should be positive 4q to apply

For B, the 2q when distributing with the parentheses should be negative 2q to work with the expression above

Hope this helps!

None of these

Step-by-step explanation:

-6 +4q +(-6q)?

Combine like terms

-6 -2q

Factor out -2

-2(q+3)

The first answer given has -6q-4q = -10q

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
