Similar triangles have corresponding sides with proportional lengths.

AB/BC = DE/EF

5/9 = 7.5/EF

5(EF) = 9 * 7.5

5(EF) = 67.5

EF = 13.5

kirza4 [7]

Answer:

The selling price would be $420.

Step-by-step explanation:

In order to find the mark up, we need to multiply the amount it originally costs by the percentage it is being marked up.

$300 * 40% = $120

Now that we have the mark up amount, we add it to the original cost to get the sale price.

$300 + $120 = $420

The function f(x) is defined as (1/2)x - 7. Emma says one possible value for the function is (2, -6). Is she correct?

Yes, she is correct. If you plug 2 into the equation, you will see this:

(1/2)(2) -7
1-7
= -6

So, the pair of values is (2,-6). Emma is correct.
