Compare 6.52 & 6.520

2 answers:

5 0

6.52 = 6.520

Both numbers are the same because the 0 doesn't matter on 6.520. So you can basically write 6.52 = 6.52 you can eliminate the zero.

Hope this helps.

They are the same because if you add a zero it doesnt change it

Answer:

$\huge\boxed{\dfrac{x^2+9^2}{x-3y}+\dfrac{6xy}{3y-x}=x-3y}$

Step-by-step explanation:

Domain:

$x-3y\neq0\Rightarrow x\neq3y$

$\dfrac{x^2+9y^2}{x-3y}+\dfrac{6xy}{3y-x}=\dfrac{x^2+9y^2}{x-3y}+\dfrac{6xy}{-(x-3y)}\\\\=\dfrac{x^2+9y^2}{x-3y}-\dfrac{6xy}{x-3y}=\dfrac{x^2+9y^2-6xy}{x-3y}\\\\=\dfrac{x^2-2(x)(3y)+(3y)^2}{3y-x}=\dfrac{(x-3y)^2}{3y-x}\\\\=\dfrac{\bigg[-1(3y-x)\bigg]^2}{3y-x}=\dfrac{(-1)^2(3y-x)^2}{3y-x}\\\\=\dfrac{1(x-3y)(x-3y)}{x-3y}=x-3y$

Man is planting a section of garden with tomatoes and cucumbers the available area of the section is 130 ft.² he wants the area

Wittaler [7]

Answer: The system of inequalities would be,

x + y ≤ 130, x > 0.25y, x ≥ 0, y ≥0

Step-by-step explanation:

Here, x represents the amount to be planted in tomatoes and y represents the amount to be planted in cucumbers, ( in square ft )

Thus, the total area required ( in square ft )= x + y

Since, the available area = 130 ft²,

⇒ Total area ≤ 130 ft²

⇒ x + y ≤ 130,

∵ the area planted with tomatoes to be more than 25% of the area planet with cucumbers,

⇒ x > 25% of y

⇒ x > 0.25y

Also, area can not be negative,

⇒ x ≥ 0, y ≥ 0

The midpoint of AB is M(-2, -1). If the coordinates of A are (-7, 2), what are the coordinates of B?

slega [8]

Answer:

Coordinates of B is (3,-4)

Step-by-step explanation: $\frac{-7+x^{2} }{2}=-2$

$\frac{2+y^{2} }{2} =-1$

You multiply -2 by 2 to get -4 and then create the equation $-7+x^{2} = -4$ then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)

You multiply -1 by 2 to get -2 and then create the equation $2+y^{2} =-2$ then you subtract 2 by -2 which gives you -4 (y coordinate of B)

To check your answer use the midpoint formula $( \frac{x^{1} +x^{2}}{2} ) ( \frac{y^{1} +y^{2}}{2} )=M$

$\frac{-7+3}{2} =\frac{-4}{2} =-2\\\frac{2+ -4}{2} =\frac{-2}{2} =-1$ which will give you the midpoint (-2,-1)
