Answer:
13
Step-by-step explanation:
2(x-1)+8=4x-20
distribute 2
2x-2+8=4x-20
2x+6=4x-20
subtract 2x from both sides
6=2x-20
add 20 to both sides
26=2x
divide both sides by 2
x=13

An= -16 + (n-1)7
an= -16 + 7n - 7
an=7n -23
When the rate of change is 7
{a1 = 16, a2=-9, so the rate of rate of change is 7}
Answer:
Step-by-step explanation:
The degree of polynomial is the sum of exponents of the variables involved in the expression,hence the given degree is
