Find the equation of the line passing through the points (5,21) and (-5,-29)

Mathematics
1 answer:
Assoli18 [71]2 years ago
3 0

Answer:

Look below

Step-by-step explanation:

lets have -29 be y2 and -5 be x2

21 - (-)29

5 - (-)5

Subtracting a negative is just adding it so

21 + 29   50
5 + 5       10

50/10

this simplified, is 5/1 or 5

y=5x+b

now we need to find b, so we substitute  y and y

x = 5

y = 21

21=5*5=b

5*5 is 25

now we need to get to 21


25 -4 is 21

b = -4

y=5x-4

On Gabriela’s first birthday, her parents gave her a $50 savings account. On every birthday after that her parents added to the
valkas [14]

Answer: a_1=50,d=25 and $475 deposited into the account on her birthdays by her 18th birthday.

Step-by-step explanation:

It is given that, on Gabriela’s first birthday, her parents gave her a $50 savings account.

Initial term : a_1=50

On every birthday after that her parents added to the account, increasing the amount they deposited by $25 each year.

Common difference : d=25

It forms an AP: 50,75,100,...

nth term of an AP is

a_n=a_1+(n-1)d

Substitute a_1=50 and d=25 in the above formula.

a_n=50+(n-1)25

It represents the amount deposited into the account after n birthdays.

We need to find the amount by her 18th birthday.

Put n=18 in the above equation.

a_{18}=50+(18-1)25

a_{18}=50+(17)25

a_{18}=50+425

a_{18}=475

Therefore, $475 deposited into the account on her birthdays by her 18th birthday.

Let X denote the number of cousins of a randomly selected student. Explain the difference between StartSet Upper X equals 2 EndS
Liono4ka [1.6K]

Answer:

A. (X =4) is the event that the student has four cousins: P(X-4) is the probability of the event that the student has four cousins.

Step-by-step explanation:

An event is an individual outcome or any number of outcomes of a random experiment or trial. An even that contains only one sample point is called a simple event. A compound event contains more than 1 sample point and is formed by the union of simple points.

An event A is said to occur only and if only the outcome of the experiment corresponds to some element of A.

In the given question the first symbolic representation gives an event and the second symbolic representation gives the probability.

The probability of X = 2 or 4 is given by P (X=2) or  P (X=4) symbollically.

So A is the best choice.

The relative frequency gives the probability  so choice B,C and D are wrong.
