General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define

7/8 = 21/k

Step 2: Solve for k

Step 3: Check

Plug in k to verify it's a solution.

Answer:

Step-by-step explanation:

If a vertical line can be drawn that goes through 2 or more points on the graph, then it is not a function. That will be the case for the two graphs on the left side of your figure.

The two graphs on the right side pass this "vertical line test," so are functional relationships.

upper left: not a function

upper right: is a function

lower left: not a function

lower right: is a function

Answer:

$2,184

Step-by-step explanation:

$6,500 x 2.8% = annual interest

6,500 x 2.8% = $182 annual interest

$182 x 12 years = interest earned in 12 years.

182 x 12 = $2,184

Answer: b

Step-by-step explanation:

The answer is b because both sides of the table start with zero and both sides of the table have a continues pattern the y side(right). They are increasing by a set # of points(3).

The value of f(6)=64

Given :

The graph of an exponential function .

Explanation :

We need to find out f(6) using the given graph .

To find f(x), first we find out the function f(x) using the graph .

Pick any two points from the graph (0,1) and (1,2)

General form of exponential function is [tex]y=ab^x[/tex]

Substitute (0,1) in general equation

[tex]1=ab^0\\1=a\\a=1[/tex]

Now we plug in (1,2) in the equation

[tex]y=ab^x\\2=1(b)^1\\2=b\\b=2[/tex]

Substitute a=1, b=2 in [tex]f(x)=ab^x\\[/tex]

[tex]f(x)=1(2)^x\\f(x)=2^x[/tex]

To find out f(6), we plug in 6 for x  in f(x)

[tex]f(x)=2^x\\f(6)=2^6\\f(6)=64[/tex]

We can solve this problem by testing the solution against each system of equations. We'll do this by substituting the point into each equation for each system.

Answer:

After n passing, the total number of people knowing the secret [tex]= 2^n[/tex].

After 10 passing, 1024 peoples know the secret.

Step-by-step explanation:

Given that each friend can pass the secret to 2 people.

On 1st pass:

Total number of people knowing the secret = 1+1=2

On 2nd pass:

Total number of people knowing the secret = 1+1+1x2=4

On 3rd pass:

Total number of people knowing the secret = 1+1+2+2x2=8

This can be written as [tex]1+1+2+2^2=1+1+2+2^{3-1}=8[/tex]

Or, [tex]1+S_3=8[/tex], where [tex]S_3=1+2+2^{3-1}[/tex].

So, for the [tex]n^{th}[/tex] pass:

Total number of people knowing the secret = [tex]1+1+2+2^2+\cdots+2^{n-1}=1+S_n, where, S_n = 1+2+2^2+\cdots+2^{n-1}[/tex].

As [tex]S_n[/tex] is the sum of geometric progression of n terms having the first term, [tex]a_1=1[/tex], and the common radio [tex]r=2[/tex].

So, [tex]S_n = \frac{a_1(r^n-1)}{r-1}[/tex]

[tex]\Rightarrow S_n =\frac{1(2^n-1)}{2-1}=2^n-1[/tex].

Hence, after n passing, the total number of people knowing the secret

[tex]=1+S_n = 1+2^n-1=2^n.[/tex]

After, 10 passing, put n=10.

Total number pf peoples know the secret [tex]= 2^{10}=1024.[/tex]

Answer:

y= -6/5x -3

Step-by-step explanation:

So for now lets bring it into mx + b format

Subtract 6x from both sides to isolate y which is also called subtraction property of equality.

so 5y = -6x -15

Now you divide both sides by 5 which is called division property of equality.

You now have y = -6/5x - 3

y= -6/5x -3 is the slope intercept form of the standard form equation of 6x + 5y = -15.

Hope this helps!

Given:

Total number of invited people = 450

Total number of people who accept the invitation = 315

To find:

The percent of the people who accepted the invitation.

Solution:

We need to find 315 is what percent of 450.

[tex]\%=\dfrac{\text{Number of invited people - Who accept the invitation}}{\text{Number of invited people}}\times 100[/tex]

[tex]\%=\dfrac{450-315}{450}\times 100[/tex]

[tex]\%=\dfrac{135}{45}\times 10[/tex]

[tex]\%=3\times 10[/tex]

[tex]\%=30[/tex]

Therefore, 30% of the people accepted the invitation.
