Each table represents some values of a function. If the slope between two pairs of points are equal, assume the function is line

kolbaska11 [484]

The slope of a function is the ratio of the rise (y2 - y1) and the run (x2-x1) of a function, In this case the slope would be (1 - 0) / (1-0) = 1. The y-intercept would be the y value when x is zero. From the table we see this will have a value of zero. The equation for this function would be y = x. We use the said equation to fill the blanks in the table.

Simplify the expression. Write the answer with positive exponents only. Assume the variable represents a nonzero real number.

luda_lava [24]

Answer:

$\frac{1}{w^{29}}$

Step-by-step explanation:

The given expression is $\frac{w^{-7}(w^{-9})^2}{w^4}$ .

Since, $w^{-7}=\frac{1}{w^7}$

And $w^{9}=\frac{1}{w^9}$

Expression will become,

$\frac{w^{-7}(w^{-9})^2}{w^4}=\frac{\frac{1}{w^7}(\frac{1}{w^9})^2}{w^4}$

$=\frac{\frac{1}{w^7\times w^{18}}}{w^4}$

$=\frac{\frac{1}{w^{(7+18)}}}{w^4}$

$=\frac{1}{w^{25}}\times \frac{1}{w^4}$

$=\frac{1}{w^{25}\times w^4}$

$=\frac{1}{w^{29}}$

Therefore, Simplified form of the given expression will be $\frac{1}{w^{29}}$ .

The relationship between the number of pounds (lb) of peanuts and the price

Rom4ik [11]

The answer to the question "What is the unit price of peanuts?" is option B: The unit price of the peanuts as shown on the graph $6/1lb

By carefully observing the graph:

The price of the peanuts is on the vertical axis of the graph

The weight(pounds) of the peanut is on the horizontal axis

From the graph:

The price of 1 pound of peanut is $6

The price of 2 pounds of peanut is $12

The price of 3 pounds of peanut is $18

The price of 4 pounds of peanut is $24

The price of 5 pounds of peanut is $30

Therefore, the unit price of the peanuts as shown on the graph $6/1lb
