Divide (6x3y2 + 12x2y - 8xy) by (2xy)

Mathematics
1 answer:
rosijanka [135]2 years ago
5 0

Answer:

Step-by-step explanation:

6x³y² = 2 * 3 * x³ * y²

12x²y = 2 *3 * 2 * x² * y

8xy    = 2 *  2 * 2 *x * y

GCF = 2xy

6x³y² + 12x²y - 8xy = (2xy * 3x²y) + (2xy * 6x) - (2xy * 4)

                               = 2xy *(3x²y + 6x - 4)

\dfrac{6x^{3}y^{2}+12x^{2}y-8xy}{2xy}=\dfrac{2xy*(3x^{2}y+6x-4)}{2xy}\\\\\\= 3x^{2}y + 6x - 4

52 companies; 25% increase find original amount?
Vlada [557]
To find your answer, you would find 25% of 52. To find 25% of 52, you would multiply 52x.25.
52x.25=13
Now you need to subtract 52-13. 52-13 is 39. The original amount is 39 companies.

Solve the system by graphing or using a table.<br> 2x+4y=12 <br>x+y=2
Molodets [167]

Answer: x = -2 and y = 4


Step-by-step explanation:

We have given a system of equations

2x + 4y =12   ...........(1)

and

x + y = 2         .............(2)

Now to plot them in graph we need to find the points of the above linear equations .

From equation 1  ,we get

4y=12-2x\\\Rightarrow\ y=\frac{12-2x}{4}\\ \Rightarrow\ y=3-\frac{x}{2}\\\text{Put x=0, then} \\y=3-\frac{0}{2}=3\\\Rightarrow\ \text{Put x=6}\\y=3-\frac{6}{2} =3-3=0

So get the points (0,3) and (6,0).

From equation 2 ,we get

y=2-x\\\text{Put x=0}\\y=2-0=2\\\text{Put x=2}\\y=2-2=0

So we get the points (0,2) and (2,0).

So after plotting these points we get two lines intersecting at (-2,4).

Therefore our solution is x=-2 and y= 4.
