Answer:

B. y= - (0.25)^x+ 4

C. y= - (3)^x+4

Step-by-step explanation:

There is no impediment in an exponential function, so all of the have the domain (-infinity, infinity).

In an exponential function in the following format:

-a^{x} + b

The range is (-infinity, b).

So these following functions apply:

B. y= - (0.25)^x+ 4

C. y= - (3)^x+4

A and D have ranges from negative infinity to negative four.

The equation that can be used to find the number of wolves in the state on January 1 is w - 23 = 84

<h3>How to represent a situation with an equation?</h3>

A zoologist is recording the loss of wolves in her state. She notes the number of wolves, w, in the state on January 1. One year later, there were 84 wolves in the state, which is 23 fewer wolves than were in the state a year earlier.

The equation that can be used to find the number of wolves in the state on January 1 can be calculated as follows:

where

  • w = number of wolves in the state January 1.

Therefore, the equation to represent the situation is as follows:

w - 23 = 84

ruslelena [56]

Answer:

Step-by-step explanation:

There are 100 cm in 1 meter. the dimensions are 400cm by 250cm. depending on which way you turn them, they will fit better. if you take 400 divided by 16, you will have a row of 25 wide and if you divide 250 by 10, you will have a length of 25. you now have 25 rows of 25. 25x25 is 625 tiles.

Hope this helps

Math homework help please thanks!

Answer:

x = 5

Step-by-step explanation:

I already answer this on another question you actually made, but here it is again:

To do this, you need to use the Thales theorem.

You can actually apply this theorem and choose two sides of the figure to do it.In this case, I will choose segment LM and MN and look for a ratio with DE and EF like this:

LM/MN = DE/EF

This theorem states that you can stablish a ratio between two segments assuming that you have at least two paralels lines, like DL || EM || FN

Therefore, it's time to replace the values of those segments and solve for X:

LM/MN = DE/EF

14/16 = 6x -9 / 4x + 4

7/8 = 6x - 9 / 4x + 4

7(4x+4) = 8(6x-9)

28x + 28 = 48x - 72

72 + 28 = 48x - 28x

100 = 20x

x = 100/20

x = 5
