Answer: \Large\boxed{A.~y=3x+4}

Step-by-step explanation:

<u>Given information</u>

Slope = 3

Point = (-3, -5)

<u>Given the format of the equation</u>

Slope-intercept form: y = mx + b

  • m = Slope
  • b = y-intercept

<u>Substitute values into the equation</u>

y = (3)x + b

y = 3x + b

<u>Substitute the given point into the equation to get the value of [ b ]</u>

(-5) = 3(-3) + b

-5 = -9 + b

b = -5 + 9

b = 4

Therefore, the equation of the line is \Large\boxed{y=3x+4}

Hope this helps!! :)

d = 16.76 inches

Step-by-step explanation:

We can extend the definition of the Pythagorean theorem to 3-dimensions:

d =  \sqrt{ {x}^{2} +  {y}^{2}  +  {z}^{2}  }

Let x = 10 in

y = 10 in

z = 9 in

d =  \sqrt{ {(10)}^{2} +  {(10)}^{2}  +  {(9)}^{2}  }

d =  \sqrt{281}  = 16.76 \: in

How do you calculate a net worth statement?
marissa [1.9K]

Answer:

a. Assets - Liabilities

Step-by-step explanation:

Assets/Liabilities is a management method to minimize risk. So, it cannot be the answer.

There is no formula like "Assets + Liabilities" and "Assets x Liabilities" in accounting to calculate the net worth. Therefore, those can be eliminated.

We know that net worth is calculated by deducting all liabilities (long-term and short-term) from net assets. Therefore, option (a) is the correct answer.

In your own words, explain why when we multiply terms that have the same bases, we add the exponents.
Doss [256]

When multiplying exponents, remember the first rule: when multiplying similar bases, add powers together. 52% + 56% =? The bases of the equation remain unchanged, while the exponents' values are added together. Adding the exponents is only a quick way to get at the answer. Simply add the exponents to multiply exponential expressions with the same base. Simplify. The product rule applies because the base of both exponents is a. With a common basis, add the exponents.

Part A

Answer: The common ratio is -2

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

Explanation: 

To get the common ratio r, we divide any term by the previous one

One example:
r = common ratio
r = (second term)/(first term)
r = (-2)/(1)
r = -2

Another example:
r = common ratio
r = (third term)/(second term)
r = (4)/(-2)
r = -2
and we get the same common ratio every time

Side Note: each term is multiplied by -2 to get the next term

============================================================
Part B

Answer:
The rule for the sequence is 
a(n) = (-2)^(n-1)
where n starts at n = 1

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

Explanation:

Recall that any geometric sequence has the nth term
a(n) = a*(r)^(n-1)
where the 'a' on the right side is the first term and r is the common ratio

The first term given to use is a = 1 and the common ratio found in part A above was r = -2
So,
a(n) = a*(r)^(n-1)
a(n) = 1*(-2)^(n-1)
a(n) = (-2)^(n-1)

============================================================
Part C

Answer: The next three terms are 16, -32, 64

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

Explanation:

We can simply multiply each previous term by -2 to get the next term. Do this three times to generate the next three terms

-8*(-2) = 16
16*(-2) = -32
-32*(-2) = 64

showing that the next three terms are 16, -32, and 64

An alternative is to use the formula found in part B

Plug in n = 5 to find the fifth term
a(n) = (-2)^(n-1)
a(5) = (-2)^(5-1)
a(5) = (-2)^(4)
a(5) = 16 .... which matches with what we got earlier

Then plug in n = 6
a(n) = (-2)^(n-1)
a(6) = (-2)^(6-1)
a(6) = (-2)^(5)
a(6) = -32 .... which matches with what we got earlier

Then plug in n = 7
a(n) = (-2)^(n-1)
a(7) = (-2)^(7-1)
a(7) = (-2)^(6)
a(7) = 64 .... which matches with what we got earlier

while the second method takes a bit more work, its handy for when you want to find terms beyond the given sequence (eg: the 28th term)
