Yolanda bought 12 pounds of rice for $5 . How many pounds of rice did she get per dollar?

defon

<h3>Answer: 2.4 pounds per dollar</h3>

Explanation:

We can set up the ratio

12 pounds : 5 dollars

Then divide both parts of that ratio by 5 so that the "5 dollars" becomes "1 dollar"

12/5 = 2.4
5/5 = 1

The ratio 12 pounds : 5 dollars is equivalent to 2.4 pounds : 1 dollar

The function G(x)=-x+5 is compressed horizontally to form F(x). Which of the following could be the equation of F(x)?

Y_Kistochka [10]

The horizontal compression of a graph means that the graph has come closer to the y-axis. Horizontal stretching and compression occur when a factor is multiplied to the original equation. If the factor being multiplied is greater than 1, then the graph is compressed. If the factor being multiplied is less than 1, the graph is stretched. Therefore, in this case, a number greater than 1 must be multiplied to -x + 5.
The answer is B. F(x) = -2(x-5)

Find the inverse of the linear function y= 1/2x+3

Korvikt [17]

Answer: The inverse of the given function is $y=2x-6.$

Step-by-step explanation: We are given to find the inverse of the following linear function :

$y=\dfrac{1}{2}x+3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`(i)$

The inverse of y = f(x) is written as

$x=f^{-1}(y).$

Substituting the above in equation (i), we get

$y=\dfrac{1}{2}x+3\\\\\Rightarrow y=\dfrac{1}{2}f^{-1}(y)+3\\\\\Rightarrow \dfrac{1}{2}f^{-1}(y)=y-3\\\\\Rightarrow f^{-1}(y)=2(y-3)\\\\\Rightarrow f^{-1}(y)=2y-6.$

Thus, the inverse of the given function is $y=2x-6.$
