The factorization of x2 + 3x – 4 is modeled with algebra tiles. What are the factors of x2 + 3x – 4? (x + 4) and (x – 4) (x + 3) and (x – 4) (x + 4) and (x – 1) (x + 3) and (x – 1

Step-by-step explanation:

x2 + 3x - 4

First we will multiply 4 by 1 = 4 factors of 4 are 1 and 4 so

x2 + 4x - x - 4

x (x + 4) - 1( x + 4)

(x + 4) and (x - 1) are the factors

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
