Two rules for creating a pattern are given below. Each rule begins with a number called the input and creates a number called the output. Rule 1: Increase the input by 4 to get the output.
Rule 2: Multiply input by 2. Then subtract 1 to get the output.

Which input and output table works for both rules?

Choose 1

A

Step-by-step explanation:

You can just check all of them in a minute.

Input               Output               Rule 1               Rule 2

  5                       9                  5 + 4 = 9 ✔      (5 × 2) - 1 = 9 ✔

 10                     14                10 + 4 = 14 ✔    (10 × 2) - 1 = 19 ❌

  8                      15                 8 + 4 = 12 ❌    (8 ×  2) - 1 = 15 ✔

Only the first one (A) works with both rules.

I hope it helps. Please choose my answer as the BRAINLIEST.

(x+3)(x+7)

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
