Answer:
B
Step-by-step explanation:
The graph is a sine curve but multiplied by -1
Answer:
-5n + 8
Step-by-step explanation:
<u>1. What is the difference?</u>
The sequence goes down by 5. This means that the formula will have -5n in it.
<u>2. Work out the term before the first term.</u>
The first term is 3, and we know that the sequence goes up by 5. So, to get the term before 3 we would add 5.
3 + 5 = 8 Remember, this is positive 8. (+8)
<u>3. Put that term at the end of the equation. </u>
We have -5n already and we just worked out the term before the first one which is positive 8 - so put that at the end of the equation.
-5n + 8 This is our answer!
Just to prove it works:
<em>Substitute: n = term</em>
Lets see if we can get the 3rd term which is -7. (n = 3)
-5(3) + 8
-15 + 8 = -7
See, it works!
Answer:
Step-by-step explanation:
Okay, so hopefully my crude diagram helps you visualize the problem. When in doubt, always draw a picture.
All I did was graph the points and formed a line.
Slope: It's going to be 0 because it doesn't change at all (no different y values)
(y2-y1)/(x2-x1) = (6-6) / (4-2) = 0/2 = 0
Y intercept is where the line crosses the y axis- this is also where x=0 (find it in your chart!)
Equation is y= 6; I don't know how to explain this, but trust me, it's right
Answer:
Yes, it is a graph
Step-by-step explanation:
Lets write this out:-
z² + z + 4z³ + 4z²
z² will become 1z² because when ever there is a varaible, and before it there is NO coefficient the coefficient automatically becomes 1. Same is with z. z will be come 1z.
Lets write it out again:-
1z² + 1z + 4z³ + 4z²
Combine like terms:-
1z² + 1z + 4z³ + 4z²
(1 + 4)z² = 5z²
1z + 5z² + 4z³
So, when combining like terms in z² + z + 4z³ + 4z² the answer is
1z + 5z² + 4z³.
