|2x + 11| =2(x + 1) solve the absolute value
Answer:
Step-by-step explanation:
|2x + 11| = 2(x+1) to find the absolute value we write two equations
2x + 11 = 2x + 2 or
2x + 11 = -2x - 2 for the first equation
2x + 11 = 2x + 2 export like terms to the same side of the equation
2x - 2x = 2 - 11
0 = -9 this expression is wrong now let's try second equation
2x + 11 = -2x - 2 export like terms to the same side of the equation
2x + 2x = -2 - 11
4x = -13 divide both sides by 4
x = -13/4

What is ∑n=16[4(−5)n−1] equal to?
Answer:
This will be the sum of a geometric series where the first term is 4
The common ratio is -5
And we will have 6 terms.....so....the sum is
first term [ 1 - common ratio^number of terms ] / [ 1 - common ratio ] =

P( Drive to school | Sophomore ) = [?]
Answer:
P(Drive to school | Sophomore) = 0.07 (nearest hundredth)
Step-by-step explanation:
A probability is conditional if it depends on what has already happened.
P(Drive to school | Sophomore) means:
The probability that a student "drives to school" given that they are a "sophomore".
Using the conditional probability formula:
P(B | A) = P(B ∩ A) ÷ P(A)
⇒ P(Drive to school | Sophomore) = P(Drive to school ∩ Sophomore) ÷ P(Sophomore)
Reading from the two-way table, there are 2 people that drive to school AND are a sophomore.
Adding all the values in the table gives us the total number of students: 2 + 13 + 25 + 25 + 20 + 5 + 3 + 2 + 5 = 100
⇒ P(Drive to school ∩ Sophomore) = 2/100 = 0.02
Adding all the values in the sophomore line of the table gives us the total number of sophomores: 2 + 25 + 5 = 30
⇒ P(Sophomore) = 30/100 = 0.3
Now plug these values into the formula:
P(Drive to school | Sophomore) = P(Drive to school ∩ Sophomore) ÷ P(Sophomore)
P(Drive to school | Sophomore) = 0.02 ÷ 0.3
= 1/15
= 0.07 (nearest hundredth)

Jim started reading at 6:45. He read for 1 hour and 20 minutes. When did Jim stop reading?
Jim stopped reading at 8:05, after reading for 1 hour and 2 minutes when we started at 6:45.
How do we add time?In time problems, we need to know the relations between seconds, minutes, hours, and days.
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds.
How do we solve the given question?We are informed that Jim starts reading at 6:45.
He reads for 1 hour and 20 minutes.
We add this time to the time he starts reading to find the time when Jim stops reading.
First we add hours, 6 + 1 = 7 hours.
Now we add minutes, 45 + 20 = 65 minutes. But we know 60 minutes = 1 hour, so we can say 65 minutes = 1 hour and 5 minutes.
So when we calculate the total time, we get,
Jim stopped reading at 7 + 1:05 = 8:05.
∴ Jim stopped reading at 8:05, after reading for 1 hour and 20 minutes when we started at 6:45.

A password is to be made from a string of five characters chosen from the lowercase letters of the alphabet and the numbers 0 through 9.
Using the Fundamental Counting Theorem, it is found that for each case, the total number of outcomes is:
a) 60,466,176.
b) 5,961,600.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
Item a:
No restrictions, hence for each of the five characters, there are 36 outcomes, hence [tex]n_1 = \cdots = n_5 = 36[/tex].
Then, the possible number of passwords is:
[tex]N = 36^5 = 60466176[/tex]
Item b:
The letters and the digits have to be alternated, hence:
Starting with a letter, [tex]n_1 = n_3 = n_5 = 36, n_2 = n_4 = 10[/tex].Starting with a digit, [tex]n_1 = n_3 = n_5 = 10, n_2 = n_4 = 36[/tex].Then, the possible number of passwords is:
[tex]N = 36^3 \times 10^2 + 10^3 \times 36^2 = 5961600[/tex]

Answer the question below using the following amortization table.
What is the regular monthly payment?
O $352.15
O $703.01
O $1758.17
O $1055.16
Answer: $1,758.17
Adding the principal paid and interest paid will result in $1,758.17 for every month/column.
For example,
Month 21 - $688.68 + $1,069.49 = $1,758.17
Month 22 - $692.73 + $1, 065.44 = $1,758.17
And so on..
As $1,758.17 is the constant total when you add principal paid and interest paid in every month, that is your answer.

6t-3=21 solve the two setp equation and show your work and check the soultion
Answer:
t=4
Step-by-step explanation:
6t-3=21
6t=21+3
t=24/6
t=4
Checking,
6t-3=21
6*4-3=21
24-3=21
21=21
True.
Answer:
t = 4
Step-by-step explanation:
1. Group all constants on the right side of the equation
6t-3=21
Add 3 to both sides:
6t-3+3=21+3
Simplify the arithmetic:
6t=21+3
Simplify the arithmetic again:
6t=24
2. Isolate the t
Divide both sides by 6:
[tex]\frac{6t}{6}=\frac{24}{6}\\ \\[/tex]
Simplify the fraction:
[tex]t=\frac{24}{6}[/tex]
Find the greatest common factor of the numerator and denominator:
[tex]t=\frac{4\cdot6}{1\cdot6}[/tex]
Factor out and cancel the greatest common factor:
t=4

Pls help me with this and an explanation
Answer:
The relationship in this equation is linear, but not proportional. If it was proportional, then replacing x with nx should give ny as the answer. Example:
y = 3x
Replace x with 2x.
y' = 3(2x) = 2(3x) = 2y
y' = 2y
This is proportional. But if you replace x with 2x in
y = 3x + 5,
you will not get 2y for y'. This case is not proportiona
Answer:
If two quantities are proportional, then they have a constant ratio. If the ratio is not constant, the two quantities are said to be non-proportional. We will make tables and look at the relationship between the variables to determine proportionality.
Step-by-step explanation:
If we were to graph this the vertices would be (0,5), (1,8) then after that the vertices are not constant therefore making it NOT a proportional relationship
y = 3x
Replace x with 2x.
y' = 3(2x) = 2(3x) = 2y
y' = 2y
This is proportional. But if you replace x with 2x in
y = 3x + 5,
you will not get 2y for y'. This case is not proportional

How to find the area of a triangle: base times height divided by 2
The equation will be 6.8 times 6.4 divided by 2 = 21.76
This is the area of one triangle, there is 4 triangles
(6.8 from get this length from the square which has all four sides the same length)
There are 4 triangles, so times 21.76 by 4, to get 88.04
fianally, you get the area of a square by doing length times height
6.8 times 6.8 = 46.24
then all all the area together. 88.04+46.24=134.28
