Skylar wanted to show the proportional relationship between the dollar value of the original investment, x, and its value after
suter [353]

After checking the information of the table, it is to notice that the table fulfills the behavior of a <em>direct</em> relationship described by the <em>linear</em> equation y = 0.9 · x. #SPJ1

<h3>How to analyze a relationship between the two variables</h3>

Let be <em>x</em> and <em>y</em> the <em>original</em> investment and the value after applying the change, both in monetary units. A <em>direct</em> relationship is observed by following this model:

y = (1 + r/100) · x     (1)

Where <em>r</em> is change rate, in percentual units.

After checking the information of the table, it is to notice that the table fulfills the behavior of a <em>direct</em> relationship described by the <em>linear</em> equation y = 0.9 · x. #SPJ1

<h3>Remark</h3>

The table of the <em>change</em> in investment with respect to <em>initial</em> investment is missing and is now introduced below:

<em>(x₁, y₁) =</em> (75, 7.5), <em>(x₂, y₂) =</em> (100, 10), <em>(x₃, y₃) =</em> (200, 20), <em>(x₄, y₄) =</em> (300, 30), <em>(x₅, y₅) =</em> (400, 40)

Matthew made a fruit salad, in which the ratio of blueberries to red grapes is 8:6. If Matthew used 28 blueberries, how many red
Inga [223]

Answer:

Step-by-step explanation:

Let's look at some other ratios that equal 8:6  We could increase them or decrease them.  For instance if we cut one in half we cut the other one in half, so 8:6 would be the same ratio as 4:3.  With the same thinking if we double one we double the other so 8:6 s the same ratio as  16:12.  Now, we want to go from 8 to 28.  What do we multiply 8 by to get to it?  Or, it might be easier to use 4:3 and see what you multiply 4 by.  Then you multiply 3 by that same number to get the other number.

Let me know if that doesn't make sense.
