Answer:

b.No

Step-by-step explanation:

given 3x-4=y

subsisting the point (2,6) we get -6 and not 6

therefore (2,6) is not a solution and thus it does not lie on the graph

marusya05 [52]

Answer:

$\large\boxed{(x^2+4x+8)(2x-1)=2x^3+7x^2+12x-8}$

Step-by-step explanation:

Use FOIL: <em>(a + b)(c + d) = ac + ad + bc + bd</em>

$(x^2+4x+8)(2x-1)\\\\=(x^2)(2x)+(x^2)(-1)+(4x)(2x)+(4x)(-1)+(8)(2x)+(8)(-1)\\\\=2x^3-x^2+8x^2-4x+16x-8\qquad\text{combine like terms}\\\\=2x^3+(-x^2+8x^2)+(-4x+16x)-8\\\\=2x^3+7x^2+12x-8$

One worker earned $6,450. I’m assuming you put the comma in the wrong area and the total of money they earned together was $103,200. The way I got $6,450 per worker was by dividing $103,200 by the 16 workers. And the outcome of that was $6,450.
