Answer:

It is 39 cupcakes.

Since he charges $2 per cupcake (39), it is 78.

He makes profit so subtract 30 from 78 and you get $48.

Find the equation of the line with Slope =5 and passing through (9,51)

BaLLatris [955]

Answer:

The equation of the line that passes through the point (9,51) with a slope of 5

is

y=5x+6

Step-by-step explanation:

You want to find the equation for a line that passes through the point (9,51) and has a slope of 5.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was 5. So you can right away fill in the equation for a line somewhat to read:

y=5x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(9,51). When x of the line is 9, y of the line must be 51.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the 5 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (9,51).

So, why not plug in for x the number 9 and for y the number 51? This will allow us to solve for b for the particular line that passes through the point you gave!.

(9,51). y=mx+b or 51=5 × 9+b, or solving for b: b=51-(5)(9). b=6.

What is the recursive of this:

abruzzese [7]

Answer:

$a_n=a_{n-1}+2^{n-1}\ \ n>1$

Step-by-step explanation:

Recursive Sequence

We are given the following sequence:

-1, 1, 5, 13...

It's required to find the recursive term for the sequence.

A recursive formula calculates each term as a function of one or more previous terms.

To find the recursive formula, we must find a pattern and transform it into a math expression.

Let's write the sequence, and below it, the difference of consecutive terms:

-1, 1, 5, 13...

+2, +4, +8

Note the difference between consecutive terms is always a power of 2, starting from 2^1, 2^2, 2^3.

The exponent is one less than the number of the term, thus:

$a_n-a_{n-1}=2^{n-1}$

Thus:

$\mathbf{a_n=a_{n-1}+2^{n-1}\ \ n>1}$

Testing:

n=1

$a_1=-1$ (given).

n=2

$a_2=a_{1}+2^{2-1}=-1+2^{1}=1$

n=3

$a_3=a_{2}+2^{3-1}=1+2^{2}=5$

n=4

$a_4=a_{3}+2^{4-1}=5+2^{3}=13$
