Answer:
22°C
Step-by-step explanation:
(16 + 20 + 24 + 28 + 28 + 23 + 15)/7 = 22°C
Y = -4x - 9
The new line has the same slope as the one above, that is - 4
A y intercept means the point (in this case) is 0,3 [The x value is 3]
y = -4x + b Now use (0,3)
3 = 0 + b
b = 3
y = - 4x + 3 is the line you want.
Answer:
11+2n
Step-by-step explanation:
Arithmetic sequence=a+(n-1)d
a=first number
n=nth term
d=difference
a=9
n=?
d=-2
So let's solve
9+(n-1)(-2)
9+(2n+2)
9+2n+2
Collect like terms
9+2+2n
11+2n
So the nth term is 11+2n
