x4−7x3−9x2−8x−5

x

Step-by-step explanation:

Let's solve for a.

ax=x4−7x3−9x2−8x−5

Step 1: Divide both sides by x.

ax

x

=

x4−7x3−9x2−8x−5

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
