One number is 5 more than twice another and their sum is 23. which of the following system of equations represents the word problem? x + y = 23 and y = 2x + 5 y = x + 5 and y + 2(x + 5) = 23 y = 2(x + 5) and x + y = 23

x+y = 23

y = 2x + 5

Step-by-step explanation:

One number is 5 more (Add 5) than twice another (2 times x)

y = 2x + 5

the sum is 23 so x + y = 23

x + y = 23 and y = 2x + 5 represents the word problem One number is 5 more than twice another and their sum is 23

Solution:

Given that One number is 5 more than twice another and their sum is 23

Let the two numbers be "x" and "y"

Where one number let it be x is 5 more than twice the another number y and sum of these number is 23

y = 5 + 2x   ….  (1)

Sum of numbers = 23

x + y = 23  …  (2)

Hence the above two equations x + y = 23 and y = 2x + 5 represents the word problem

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

i belive those are the ones that are under 90 degreese.
