Y is inversely proportional to x, when Y = 7, x = 4.
babymother [125]

Answer:

The given statement  Y = 7, x = 4 is False.

Step-by-step explanation:

We are given:

Y is inversely proportional to x, when Y = 7, x = 4.

We need to tell if the statement is True or False: the constant of proportionality, k, is 20.

Y is inversely proportional to x

We can write it as: y\:\alpha \:\frac{1}{x}\\y=\frac{k}{x}

Now, we need to check when Y=7, x = 4 is true or false

We are given k = 20

Now, I can find value of y, by putting values of k and x in the equation:

y=\frac{k}{x}\\y=\frac{20}{4}\\y=5

When we put x = 4, and k =20, we get Y=5 and not Y=7

So, The given statement  Y = 7, x = 4 is False.

Using distributive property -1/6(6y+7)??
Solnce55 [7]

Hello!

The distributive property states, a(b + c) = ab + ac. Normally, we would simplify the values inside the parentheses first, and then multiply, but since these two values are not alike terms, we would need to use the distributive property.

-1/6(6y + 7) is also equal to -1/6(6y) + -1/6(7), so with that, we can simplify the expression.

-1/6(6y) + -1/6(7) can be simplified to -y + -7/6.

Therefore, using the distributive property, the answer is -y - 7/6.

tamaranim1 [39]

Answer: The relationship between the weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper is proportional.

Step-by-step explanation:

Let us assume here, in this situation that each page has the same weight so if i want to find the weight of the complete stack, I will multiply the number of sheets of paper by the weight of a single sheet of paper.
