Answer:

Yes

Step-by-step explanation:

f(x) = x³ − 9x² + 11x + 21

f(3) = (3)³ − 9(3)² + 11(3) + 21

f(3) = 27 − 81 + 33 + 21

f(3) = 0

Need help with middle two questions... I’ll give points
nignag [31]

Answer:

ok sorry i could not put this into a formula im have to go but i will show you a really easy way.

Step-by-step explanation:

for number 1 i got (7,-1)

This is because there is a slope of 1/1 between these two points. so i plotted the two points on the graph. The distance between the two points is 4. so i followed the slope 4 times and thats what i got.

The correct way for doing number 1 is using the distance formula i believe but im running out of time

for the second one i got  (3, -1/2)

we do this by using the midpoint formula.

The first picture is for number one and the second for number 2

if you have any questions feel free to ask in the comments

Write an e explicit formula for an, the nth term of the sequence 22, 19, 16, ...<br>​
alexira [117]

Answer:

a_{n} = 22 + (-3)(n - 1)

Step-by-step explanation:

The first term is 22. It looks like each term after that is the term before, plus a negative 3.

a-sub-one  = 22

common difference = d= -3

Formula for a_{n}:

a_{n} = 22 + (-3)(n - 1) = 25 - 3n
