Answer:
aₙ= 47 -3n
Step-by-step explanation:
44, 41, 38, 35, 32
This is AP with 1st term of 44 and common difference of -3
nth term of this AP:
- aₙ= a₁+(n-1)d= 44+(n-1)*(-3)= 44 - 3n+3= 47-3n
He could type 3 3/7 in one hour.I think this because since it is 1/3 you would have to multiply it by 3.So you multiply 1/3 by 3,It would give one hour.When you multiply 1 1/7 by 3 it would give you 3 3/7.
Answer:
(x,y) = (6/5, 38)
Step-by-step explanation:
y = y right?
so, you just substitute both of those equations
26+10x = 44-5x
26 -44 = -5x -10x
x = 6/5
then substitute x into ANY of these two equations
let's say we want the second one
y = 44 - 5 × 6/5
y = 38
I'm not sure but I think that first number there might be a 20 and not a 26. If that's true then, solving the same way you'd have
(x,y) = (8/5, 36)
Answer:
number 11 is slope=3, then number 12 is slope=-2, then number 13 is slope=4 and number 14 is slope =1. i got my answers by looking at the x axis. In a y=mx+b whatevers infront of the x is your slope. idk what 15 is though its weird lol Good luck! :)

F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
