Mia is tracking her savings account balance . She knows the equation to find her balance y in any year t, but she can't remember
motikmotik

Complete question is;

Mia is tracking her savings account balance. She knows the equation y = 8000p^(t) can be used to find her balance y in any year t, but she can't remember what p represents. Her balance 3⅔ years after opening her account, is $9,905.54. What is the value of p?

Answer:

p = 1.06

Step-by-step explanation:

We are told that the equation y = 8000p^(t) can be used to find her balance y in any year t.

Now, we are given t = 3⅔ = 11/3 years

Also, we are given balance after 11/3 years as;

y = $9,905.54

Thus;

Plugging the relevant values into y = 8000p^(t), we have;

9,905.54 = 8000p^(11/3)

p^(11/3) = 9905.54/8000

p = (9905.54/8000)^(3/11)

p = 1.06

Which is the function represented by the table? A 2-column table with 4 rows. Column 1 is labeled x with entries negative 2, neg
Serggg [28]

Answer:

f(x)=4x

Step-by-step explanation:

Given: See the attached image

To find: the function represented by the table

Solution:

A function is a relation in which every element of the domain has a unique image in the co-domain.

f(-2)=-8=4(-2)\\f(-1)=-4=4(-1)\\f(0)=0=4(0)\\f(1)=4=4(1)

Here, -2,-1,0,1 are elements in the domain and -8,-4,0,4 are elements in the co-domain.

Therefore, the table represents the function f(x)=4x

If f(x) = 5x - 2 and g(x) = 2x + 1, find (f + g)(x)
SVEN [57.7K]

Answer:

(f + g)(x) = 7x - 1

Step-by-step explanation:

Given :  f(x) = 5x – 2 and g(x) = 2x + 1

We have to find  (f + g)(x)

Consider  (f + g)(x) = f(x) + g(x)

Also, given  f(x) = 5x – 2 and g(x) = 2x + 1

Substitute, we have,

f(x) + g(x) = 5x - 2 + 2x + 1

Like Terms are terms having same variable with same degree.

Simplify by adding like terms,  we have,

f(x) + g(x) = 5x + 2x - 2  + 1

f(x) + g(x) = 7x  - 1

Thus, (f + g)(x) = 7x - 1
