Answer:
20-2(n-1)
Step-by-step explanation:
The general term (or the nth term) of this sequence is [20-2(n-1)].
Verification:
1st term = 20-2(1-1) = 20-2(0) = 20-0 = 20
2nd term = 20-2(2-1) = 20-2(1) = 20-2 = 18
3rd term = 20-2(3-1) = 20-2(2) = 20-4 = 16
4th term = 20-2(4-1) = 20-2(3) = 20-6 = 14
I need help pronto {(2,2,),(-5,2),(6,6),(9,4),(4,9)} is it a function and explain please

Answer:
yes, because the x values are all different. if the y values are the same it doesnt matter.
Step-by-step explanation:
Answer:
[A] use the complementary relationship between sine and cosine to rewrite sin(x + y) as cos(pi/2-(x+y)). apply the cosine sum identity. then simplify using sin(–y) = –sin(y) and cos(–y) = cos(y).
Step-by-step explanation:
i got it right
screw that other person l0l
note that sin(-x)=-sin(x) and cos(-x)=cos(x)
so sin(-y)=-sin(y) and cos(-y)=cos(y)
or something like that idfk
Answer:
Domain :Set of all real values
Range : -5
Step-by-step explanation:
Here we see the blue line. Assuming it to be the graph of the function we are about to find Domain for.
Here we see that the graph is a straight line , parallel to x axis at y=-5
Hence the function will be
f(x)=-5
Also for every values of x, y =-5. Hence it is defined for all values of x. So the Domain is Set of All Real numbers
However,
For every value of x, the value of y is constant that is -5. Hence The range of f(x)=-5 is {-5}
