Answer:

-63

Find common difference:

  • -5 -(-3)
  • -5 + 3
  • -2

nth term:

  • a + (n-1)(d)      <u>[where a is first term, d is common difference]</u>
  • -3 + (n-1)(-2)
  • -3 -2n + 2
  • -2n -1

So 31st term:

  • -2(31) -1
  • -63

Given: Z = 0.43Y + 12 ; What is Y when Z = 28
jolli1 [7]
Z = 0.43Y + 12; Z = 28
28 = 0.43Y + 12; insert value of Z
16 = 0.43Y; subtract 12 from both sides
37.21 = Y; divide both sides by 0.43; rounded to nearest hundredth

Answer:

  y = 5x - 7

Step-by-step explanation:

We can make an equation for the perpendicular line by swapping the x- and y-coefficients, negating one of them. Then we can use that form with the given point to see what the constant is.

  10x -2y = ...

Removing a common factor of 2 gives ...

  5x -y = 5(2) -(3) = 7 . . . .  using (x, y) = (2, 3), we can find the constant

Solving for y, we get ...

  5x -7 = y . . . add y-7

  y = 5x -7 . . . write in the desired form
