The sequence -6,-11,-16,-21,-26 is arithmetic true or false ?

True.

Step-by-step explanation:

In this case, you are subtracting 5 each time to get from one term to another. The definition of a arithmetic sequence is that the difference between any given numbers that are next to each other of the sequence have the same change.

For example:

-11 - (-6) = -5

-16 - (-11) = -5

-21 - (-16) = -5

Note that the change has been consistently -5.

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16
