Check that 2b+b and 3b have the same value when b is 1,2, and 3. Do 2b+b and 3b have the same value for all values of b? Explain your reasoning

Expression 2b+b and 3b have same values for all values of b.

Step-by-step explanation:

Given the two expression and and values of b as 1, 2 and 3.

Consider first expression that is, .

Substituting the value of ,

....1

Substituting the value of ,

....2

Substituting the value of ,

....3

Consider second expression that is, .

Substituting the value of ,

....4

Substituting the value of ,

....5

Substituting the value of ,

....6

For value of b=1, equation 1 and equation 4 are same, for value of b=2, equation 2 and equation 5 are same and for value of b=3 equation 3 and equation 6 are same.

Therefore both expression are same for all values of b.

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
