What is the equation of the line that passes through the point (7,−3) and has an undefined slope
Answer:
The equation of the line that passes through the point (7,−3) and has an undefined slope will have the equation: x = 7.
Step-by-step explanation:
As the line has an undefined slope, meaning the line is vertical.
As we know that the vertical line passes through (7, -3), so it can never pass through any x-value other than x = 7, although it can pass through infinite y-values.
so the equation of line will be: x = 7
Therefore, the equation of the line that passes through the point (7,−3) and has an undefined slope will have the equation: x = 7.

First Answer:
the slope of the line is 2.
following the equation
m = rise/run
The rise is 4 and the run is 2
4/2 = 2
Answer:
m=-2
Step-by-step explanation:
Since the line is sloping down, we know the slope is negative. To find the slope count the number of units up/down and the number of units over. In this case, pick any 2 points the line crosses through and think:
"down 4, over 2".
-4/2
-2

I start with 100 and subtract 3 repeatedly. (100 - 3, 97 - 3, 94 - 3 and so on). How many subtractions would I have to do to get the FIRST single-digit number?
Using an arithmetic sequence, it is found that you would need to do 32 subtractions
In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem:
Starts with 100, which is the first term, hence [tex]a_1 = 100[/tex].Subtracts 3, which is the common difference, hence [tex]d = 3[/tex]Then:
[tex]a_n = a_1 + (n - 1)d[/tex]
[tex]a_n = 100 - 3(n - 1)[/tex]
[tex]a_n = 103 - 3n[/tex]
To get a single-digit number, we need that:
[tex]a_n \leq 9[/tex]
Hence, solving the inequality:
[tex]103 - 3n \leq 9[/tex]
[tex]-3n \leq -94[/tex]
[tex]3n \geq 94[/tex]
[tex]n \geq \frac{94}{3}[/tex]
[tex]n \geq 31.3[/tex]
Rounding up, 32 subtractions need to be done.

what is the inverse of the function
Answer:
f⁻¹(x) = x+2 / 3
Step-by-step explanation:
Given function is:
f(x) = 3x-2
We have to find the inverse of the given function.
Put y = f(x) in given function, we have
y =3x-2
Adding 2 to both sides of the above equation we have
y+2 = 3x-2+2
y+2 = 3x
Dividing by 3 to both sides of the above equation, we have
y+2 / 3 = 3x / 3
y+2 / 3 = x
Put x = f⁻¹(y) in the above equation we have
y+2 / 3 = f⁻¹(y)
Swapping equation we have
f⁻¹(y) = y+2 / 3
Replace y with x we have
f⁻¹(x) = x+2 / 3 which is the answer.

There are n nonfiction books and 12 fiction books on a bookshelf. If one of these books is selected at

A
n
12
B
n
n +12
С
12
n
D
12
n+12
Answer:
[tex]P=\dfrac{n}{n+12}[/tex]
Step-by-step explanation:
Number of non-fiction books = n
Number of fiction books = 12
We need to find the probability of selecting a nonfiction book, in terms of n.
Total no of books = non-fiction books + fiction books
= n+12
Probability = favourable outcomes/total no of outcomes
Here, favourable outcomes = n
So,
[tex]P=\dfrac{n}{n+12}[/tex]
Hence, the probability of selecting a non-fiction is [tex]\dfrac{n}{n+12}[/tex].

En un día de temporal de lluvia el meteorólogo dijo en las noticias que la probabilidad de que lloviera ese día era del 70%. ¿Qué significa ese dato?
Answer:
Vamos a definir:
100% probabilidad de lluvia = Es seguro que ese día va a llover.
0% probabilidad de lluvia = Es seguro que ese día no va a llover.
Ahora, los valores intermedios admiten una dualidad, es decir, es posible que llueva o que no.
Particularmente en el caso del 70% significa que:
Si tenemos un dado de 10 caras, con los números {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
Y lo tiráramos, los resultados {1, 2, 3, 4, 5, 6, 7} indicarían que llueve.
Los resultados {8, 9, 10} indicarían que no llueve.
Entonces es mas probable que llueva, pero la probabilidad de que no llueva no es despreciable.

What is Elise's number?
Elise says, "If you subtract 13 from my number and multiply the difference by - 7, the result is -182
Answer:
39
Step-by-step explanation:
In words, Elise's statement can be expressed as follows:
(x-13)(-7) = -182
where x is the number. Working it out you get:
x-13 = 26
x=39
Answer:
39
Step-by-step explanation:
let's use 26 as x
26-13=13*-7=-182
-182 /-7= 26
26+13=39
A Hudson Valley farmer has 26 employees. He pays each employee $410 per week. After paying his workers for one week, the farmer has $126 left in his bank account. How much money did he have to begin with.
Given:
A Hudson Valley farmer has 26 employees.
Salary of each employee = $410 per week.
Remaining amount after one week = $126
To find:
The initial amount of money he begins with.
Solution:
We have,
Amount he pays to one employee in one week = $410
Amount he pays to 26 employee in one week = 26 × $410
= $10660
Let x be the initial amount of money he begins with.
Remaining amount = Initial amount - Amount he pays to 26 employee in one week
[tex]126=x-10660[/tex]
[tex]126+10660=x[/tex]
[tex]10786=x[/tex]
Therefore, the initial amount of money he begins with is $10786.
A rectangle has a perimeter of 38+x 38+x centimeters. The rectangle has a length of 3x−2 3x−2 centimeters and a width of x centimeters. What is the length of the rectangle? A. Substitute the dimensions of the rectangle info the perimeter formula P=2w+2l P=2w+2l b. Solve for x. C. Find the length of the rectangle.
Answer:
The length of the rectangle is 6 centimeters
Step-by-step explanation:
The perimeter of a rectangle =
P = 2L + 2W
A rectangle has a perimeter of 38+x centimeters. The rectangle has a length of 3x−2 centimeters and a width of x centimeters.
Hence:
38 + x = 2(3x - 2) + 2(x)
38 + x = 6x - 4 + 2x
Collect like terms
38 + 4 = 6x + 2x - x
42 = 7x
x = 42/7
x = 6 centimeters
The length of the rectangle is 6 centimeters
