Point J has coordinates (–3, 4) in the coordinate plane. Point K has coordinates (3, 4).
olga2289 [7]

The reflections of the two points J and K as described in the task content are; (-3, -4) and (3, -4) respectively.

<h3>Which points represents the reflection of both points across the x-axis?</h3>

It follows from convention that the reflection of a given point across the x-axis simply implies that the y-coordinate of such a point is multiplied by -1.

On this note, it follows that the points J and K given as in the task content have their reflection across the x-axis are: (-3, -4) and (3, -4) respectively.

Therefore, the reflections of the two points J and K as described in the task content are; (-3, -4) and (3, -4) respectively.

Suppose your marginal cost of making a peanut butter and jelly sandwich is constant at $10, but the marginal benefit of eating t
Softa [21]

Answer:

At most 3 sandwiches i would eat at this situation

Step-by-step explanation:

Making a first sandwich has a constant value 10$ but its marginal benefit is 12$. There is a 2$ benefit exist if i eat one.

Making the second one costs 20$ but its marginal benefit is 22$. Still 2$ benefit is exist if i eat the second one also.

Making the third one costs 30$ ant its marginal benefit also 30$. There is a even situation here. Making three sandwiches still an option.

After third one marginal benefit becomes lower than marginal cost of sandwiches.

Find the product. Enter your answer in the box below as a fraction, using the slash mark (/) for the fraction bar.
MakcuM [25]

Answer:

5/7

Step-by-step explanation:

In order to multiply fractions, multiply the numerators together and multiply the denominators together - the answers will be the numerators and denominators of the product, respectively. Also, remember that 5 can also be expressed as \frac{5}{1} in fraction form since it is a whole number.

Knowing this, multiply like so:

\frac{1}{7} · \frac{5}{1}

= \frac{5}{7}

Therefore, 5/7 is the answer.
