rows of chairs are set out for a wedding. there are 6 chairs in the first row, 14 chairs in the second row, and 22 chairs in the
fomenos
This is just a simple multi-step math problem. The first step to finding the answer is to find out the pattern of the chairs. So, we would take two of the numbers, 14 and 6, and subtract 14 from 6.

14 - 6 = 8

So now we know that the difference between the first to rows is 8 chairs. To double check this pattern you would simply subtract 14 from 22.

22 - 14 = 8

Okay, so now we are sure that the pattern is by simply adding 8 to the number of chairs in the row before. Now that we have a pattern all set, there are two different ways to solve this problem, yet I am going to use the longer method. You would simply start from 6 and keep adding on 8's until you would reach the 7th row like so:

6 + 8 = 14
14 + 8 = 22
22 + 8 = 30
30 + 8 = 38
38 + 8 = 46
46 + 8 = 54

So as you can see, the total number of chairs would be 54. This may take a little longer to do, as I happened to use the longer method for this problem. Yet I hope this still helped :)!

An exponential function is given by the equation y=3x. Using the points xx and x+1x+1, show that the y-values increase by a fact
Kobotan [32]

Answer:

Here we have the function:

y = f(x) = 3^x

Using the values:

x and (x + 1)

We need to find that the y-value increases by a factor of 3.

So we need to prove that:

f(x + 1) = 3*f(x).

Or we can see the quotient:

f(x + 1)/f(x) = 3

Here we can find the values:

f(x + 1) = y = 3^(x + 1)

f(x) = y' = 3^x

If we take the quotient, we get:

\frac{f(x + 1)}{f(x)}  = \frac{3^{x + 1}}{3^x}

Here we can use the properties:

a^n*a^m = a^{n + m}

\frac{a^n}{a^m}  = a^{n - m}

Using these in the quotient equation we get:

\frac{f(x + 1)}{f(x)}  = \frac{3^{x + 1}}{3^x} = \frac{3^x*3^1}{3^x} = \frac{3^x}{3^x}*3 = 1*3 = 3

Then:

\frac{f(x + 1)}{f(x)} = 3

f(x + 1) = 3*f(x)

So we found that the y-value increases by a factor of 3 between any two points x₂ and x₁ such that: x₂ - x₁ = 1.

Find the value of x.<br> please help
maks197457 [2]

Answer:

123 degrees

Step-by-step explanation:

Well, since we have a 4 sided figure, we know that the sum of the interior angles is 360 degrees.

(n-2)*180=(4-2)8180=360

Okay we are given 3 angles

120+43+74= 237

that means that x= 360-237

x=123 degrees
