Answer:
<em>y ≥ x - 2, and x + 2y < 4 ; Option C</em>
Step-by-step explanation:
Consider the y - intercept and slope of 1 of these given lines,
From this we can formulate the equation of 1 line;
Now consider the y - intercept and slope of the remaining line;
This creates a line with the equation as such;
From this we see that the solution of the system is such;
<em>Solution ; y ≥ x - 2, and x + 2y < 4 ; Option C</em>
Answer:
C. 20/12 = 100/x
Step-by-step explanation:
The ratio of interest is (fruit juice)/(total liquid) = x/100. The usual way that would be expressed is ...
(12 cups)/(12 cups + 8 cups) = x/100
12/20 = x/100
We note that the only answer choice with the numbers 12, 20, and 100 is C. Checking that against the expected relation above, we see that <em>both sides are inverted</em>, so the proportion of C is equivalent to the one we expect.
