Customer A spent $18 on a plate of brisket, two sides, and a drink. Customer B spent $10 on a plate of brisket and a drink. Customer C spent $57 on three plates of brisket, six sides, and four drinks. Which augmented matrix best represents the system of linear equations that could be used to determine the price of each item?

x intercept = (-1,0)   (4,0)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

answer: 193

explanation:

200-7 = 193
