Which ordered pair would form a proportional relationship with the point graphed below?

kvasek [131]

Answer:

$(x,y) = (-30,10)$

Step-by-step explanation:

Given

$(x,y) = (60,-20)$

Required:

Determine a pair with a proportional relationship

A proportional relationship is:

$k = \frac{y}{x}$

Where k is the constant of proportionality.

$(x,y) = (60,-20)$

So, we have:

$k = \frac{-20}{60}$

$k = -\frac{1}{3}$

This means that for a pair to have a proportional relation, k must be -1/3.

This is true for (c).

Where:

$(x,y) = (-30,10)$

So, we have:

$k = \frac{10}{-30}$

$k = -\frac{1}{3}$

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each.he spent a total of $47.65. If Hugh bought 3

Nookie1986 [14]

He bought 4 books

Steps:

3.95(3) + 8.95b = 47.65
<span>11.85 + 8.95b = 47.65
</span>
Now just subtract 11.85 from both sides and now the equaton shoud look like this

8.95b = 35.8

Now divide 8.95 from both sides and you get...

b=4

Hope this helps!
