The equation shown has a missing value. -2(2x-?)+1=17-4x. For what missing value(s), if any, does the equation have exactly one solution?For what missing value(s), if any does the equation have no solution?
Answer:
8
Step-by-step explanation:
There are no values for which the equation has only one solution for no solution the missing value can be anything except 16.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation shown has a missing value.
-2(2x - ?) + 1 = 17 - 4x
Applying the distributive property:
-4x + ? + 1 = 17 - 4x
? + 1 = 17
There are no values for which the equation has only one solution or unique solutions.
For no solution the missing value can be anything except 16
? + 1 = 17
? = 17 - 1
? = 16
Thus, there are no values for which the equation has only one solution for no solution the missing value can be anything except 16.

An airplane is carrying 90 passengers,which 5/6 of the capacity of the airplane.what the capacity of tge airplane?
Answer:
108
Step-by-step explanation:
the capacity of the airplane is 108 passengers.
To find the capacity of the airplane, we can set up an equation using the given information.
Let's denote the capacity of the airplane as "C".
We are given that 5/6 of the capacity (5/6C) is equal to 90 passengers.
So, we can write the equation as:
5/6C = 90
To solve for C, we can multiply both sides of the equation by the reciprocal of 5/6, which is 6/5:
C = (90) * (6/5)
C = 108
Therefore, the capacity of the airplane is 108 passengers.

Time (hours) Number of bacteria cells 0 20 1 40 2 80 3 4 5 6 Write an exponential function to model this situation. Predict the bacteria population after 11 hours.
Answer: 3, 160 || 4, 320 || 5, 640 || 6, 1280
Step-by-step explanation:
The exponential function to model this situation is [tex]P(t) = 20\times 2^t[/tex]
What is an exponential function?An exponential function is a mathematical function in the form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.
The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.
Given that, a scientist studying bacteria begins with 20 cells.
The bacteria population doubles every hour.
Let P(t) determines the population of the bacteria in 't' hours.
Hence, by the given information our function P(t) is modeled as:
[tex]P(t) = 20\times 2^t[/tex]
To find the population of the bacteria after 11 hours, put t = 11,
[tex]P(11) = 20\times 2^{11[/tex]
= 40,960
Hence the population of the bacteria after 11 hours will be 40,960.

In order for Brady to earn a B in his biology course, his test scores must average at least 80%. On the first 5 tests, he has an average of 77%. There is one test remaining in the course. What is the minimum score Brady needs to earn on the last test to receive a B in the class? Can you give a step by step explanation?
Hey there! I'm happy to help!
There were 5 tests needed to make an average of 77. These numbers have to add up to 385 (77×5) because that is what you divide by 5 to find the average which is 77.
Now, we want to find an average of 80 with 6 numbers. We multiply 80 and 6, showing us that the sum of these 6 numbers must be 480. Since 5 of these numbers are the same as with the 77 average, we know that one test score (the one Brady needs to get) is added to 385 to give us 480.
480-385=95
Therefore, Brady needs to earn a 95% on the last test to receive a B in the class.

Answer:
∫ₑ°° 1 / (x (ln x)¹⁰) dx
∫₁°° x⁻³ dx
Step-by-step explanation:
A p-series 1 / xᵖ converges if p > 1.
∫ₑ°° 1 / (x (ln x)¹⁰) dx
If u = ln x, then du = 1/x dx.
When x = e, u = 1. When x = ∞, u = ∞.
= ∫₁°° 1 / (u¹⁰) du
p = 10, converges
∫₁₀°° x^(-⅔) dx
= ∫₁₀°° 1 / (x^⅔) dx
p = ⅔, diverges
∫₁°° 2 / x^0.5 dx
= 2 ∫₁°° 1 / x^0.5 dx
p = 0.5, diverges
∫₁°° x⁻³ dx
= ∫₁°° 1 / x³ dx
p = 3, converges
∫₂°° 1/(3x) dx
= ⅓ ∫₂°° 1/x dx
p = 1, diverges

A fisher caught a large boat load of salmon. She decided to donate some of his fish to the local community, 1,672 people in all. To each person over the age of 50 she gave 16 fish and to each person under 50 she gave 96 fish. Only 3/4 of the over 50s collected their salmon and only 1/8 of the under 50s collected their fish. How many fish did the fisher distribute it total
Answer:
74 fishes
Step-by-step explanation:
Total number of people = 1672
Let us represent:
Number of people over the age of 50 = a
Number of people below the age of 50 = b
People over the age of 50 she gave = 16 fish
People below 50 she gave = 96 fish. Only 3/4 of the over 50s collected their salmon
= 3/4a collected fish = 0.75a
If a should collect = 96 fishes
0.75a =
Cross Multiply
=0.75a × 96 fishes/ a
= 72 fishes
Therefore, 3/4 of the over 50s collected 72 fishes.
1/8 of the under 50s collected their fish.
= 1/8b collected fish = 0.125b
If b people should collect = 16 fishes
0.125b people =
Cross Multiply
0.125b × 16 fishes/b
= 2 fishes.
Therefore, the total number of fishes shared
= 72 fishes + 2 fishes
= 74 fishes

Assume log bx = 0.49. Evaluate.
Logbx^2
Step-by-step explanation:
Use exponent property of logs.
logb(x²) = 2 logb(x) = 2(0.49) = 0.98
The value of logᵇ x² is 0.98 after using the logarithm properties the answer is 0.98.
What is a logarithm?It is another way to represent the power of numbers, and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
[tex]\rm a^b = c\\log_ac =b[/tex]
It is given that:
[tex]\rm log_b x=0.49[/tex]
The integer exponent:
In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
It is required to find the value of [tex]\rm log_b \ x^2[/tex]
As we know from the log property:
[tex]\rm log_a \ b^c = c \ log_a b[/tex]
[tex]\rm log_b \ x^2 = \rm 2log_b \ x[/tex]
[tex]\rm log_b \ x^2 = \rm 2(0.49)[/tex]
[tex]\rm log_b \ x^2 = 0.98[/tex]
Thus, the value of logᵇ x² is 0.98 after using the logarithm properties the answer is 0.98.
