Answer:
12 - 2n
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = 8 - 10 = - 2, thus
= 10 - 2(n - 1) = 10 - 2n + 2 = 12 - 2n
After trying to do it the hard way, i remembered the easy way.
substitution:
because x = 6 and 6 is in the range of -6 < x < 9, we only need the equation 6x^(2) + 2
f(x) = 6x^(2) + 2
f(6) = 6(6)^(2) + 2
f(6) = 6(36) + 2
f(6) = 216 + 2
f(6) = 218
Answer:
y=1/5x-4
Step-by-step explanation:
So, first we're gonna put this into point slope form, (y-y1)=m(x-x1), then we'll convert it. When you plug the numbers in, you get (y+9)=1/5(x+25)
Then, you simplify!
y= 1/5(x+25)-9
y=1/5x+5-9
y=1/5x-4
Hope this helped!
