1 answer:

6 0

To prove that it is a parallelogram, remember that the definition of a parallelogram is a quadrilateral with two pairs of parallel sides. Therefore, one way to prove it is a parallelogram is to verify that the opposite sides are parallel. From algebra, remember that two lines are parallel if they have the same slope.

Answer:

-xy^6 +2y -6

Step-by-step explanation:

(-6x^2 y^8+12xy^3-36xy^2)

-------------------------------------------

6xy^2

Divide each term by 6 in the numerator and denominator

(-6/6x^2 y^8+12/6xy^3-36/6xy^2)

-------------------------------------------

6/6xy^2

-x^2y^8 +2xy^3 -6xy^2

---------------------------------

xy^2

Divide each term by x in the numerator and denominator

-x^2/xy^8 +2x/xy^3 -6x/xy^2

---------------------------------

x/xy^2

-xy^8 +2y^3 -6y^2

---------------------------------

y^2

Divide each term by y^2 in the numerator and denominator

Remember when dividing, we subtract the exponents

-xy^8/y^2 +2y^3/y^2 -6y^2/y^2

---------------------------------

y^2 /y^2

-xy^6 +2y^1 -6

---------------------------------

-xy^6 +2y -6

Nina [5.8K]

Answer:

Step-by-step explanation:

Part A

Yes, there is a proportional relationship in Cara's. For every 5 yellow flowers, there are 3 white flowers. 5:3. I didn't see an equation that would work for the equation in the question. The equation I found on my own would be 5w/3 = y

Part B

There is no proportional relationship in Hector's. The equation would be e=h-2.
