Since there are no ordered pairs or linear systems in sight, it is undetermined whether the ordered pair fits it.

A recipe that makes 8 servings calls for 3/5 cup of flour. Jeff modifies the recipe so that it can serve 10. How many cups of fl

Blababa [14]

8 goes with 3/5: 10 goes with n (n being the number of cups)

$\frac{8}{3/5} = \frac{10}{n}$

Use cross products and we get 8n = 6
Now divide by 8
8n = 6
8 8

n= 6/8 or 3/4 of a cup of flour.

Answer:

positive
negative

Step-by-step explanation:

The thrust of the question is to make sure you understand that increasing the y-coordinate of a point will move the point upward, and decreasing it will move the point downward.

That is adding a positive value "k" to x^2 will move the point (x, x^2) to the point (x, x^2+k), which will be above the previous point by k units.

If k is subtracted, instead of added, then the point will be moved downward.

The blanks are supposed to be filled with positive , and negative .

Comment on the question

The wording of the statement you're completing is a bit odd. If k is negative (-2, for example), this statement is saying the graph is translated down -2 units. It is not. It is translated down |-2| = 2 units. The direction of translation depends on the sign of k. The amount of translation depends on the magnitude of k.

If you thoroughly understand (x, y) coordinates and how they are plotted on a graph, it should be no mystery that changing the y-coordinate will change the vertical position of the graph.
