In a paragraph, explain whether or not all geometric sequences are exponential functions.
ANTONII [103]

Answer:

In a short terms, if you have geometric sequences are most likely(99% sure) to be exponential functions because aromatic functions are the opposite of exponential. Aromatic function are used for linear equation, graphs, and functions while exponential functions will be used for exponential equations, graphs, and functions. So yes, all geometric sequences are in fact exponential functions.

Hope this is helpful.

How do you solve the system of the linear equation by substitution?<br> y=x-4<br> 4x-y=3
Bingel [31]

Answer:

x=-1/3, y=-13/3. (-1/3, -13/3).

Step-by-step explanation:

y=x-4

4x-y=3

------------

4x-(x-4)=3

4x-x+4=3

3x+4=3

3x=3-4

3x=-1

x=-1/3

y=-1/3-4

y=-1/3-12/3=-13/3

Solve for d <br> 3d - 8 = 7
taurus [48]

Answer:

The Value of d is 5.

Step-by-step explanation:

Given:

3d-8=7

We need to solve for d

Hence for solving for the term d we get;

3d-8=7

Now we will use Addition property for equality and add both side by 8 we get;

3d-8+8=7+8

3d=15

Now we will use Division property for equality and Divide both side by 3 we get;

\frac{3d}{3}=\frac{15}{3}\\

d=5

Hence the Value of d is 5.
