Answer:

C. 5/18

Step-by-step explanation:

A quadrilateral is any shape with 4 sides, therefore a rectangle is a circle while the other ones are not. Since there are 5 rectangle cards, the answer will be 5 over the number of total cars

8 triangle cards + 5 rectangle cards + 5 circle cards = 18 total cards

5 rectangle cards out of 18 total cards

5/18

C. 5/18

<h3>Answer: Choice B. f(x) = 100 - 68x</h3>

Work Shown:

Solve for y. Then replace y with f(x).

$680x + 10y - 1000 = 0\\\\10y - 1000 = -680x\\\\10y = -680x + 1000\\\\y = \frac{-680x + 1000}{10}\\\\y = \frac{-680x}{10} + \frac{1000}{10}\\\\y = -68x + 100\\\\y = 100 - 68x\\\\f(x) = 100 - 68x\\\\$
