solve for the variable c in this equation: a(c + b) = d question 2 options: or c = d/a - b or c = d/a + b or c = b - d/a or c = d/b - a
Solving the equation a(c + b) = d for variable c, the variable c = (d/a) – b. (Option A)
Equation refers to a statement that represents an equality of values of two mathematical expressions and is indicated by the sign =.
In the given equation a(c + b) = d, in order to solve for the variable c, we must isolate the c variable at one side and collect other variables on the other side of the equation.
Given equation is:
a(c + b) = d
Divide both sides by a:
(1/a)*a(c + b) = d/a
c + b = d/a
Subtract b from both sides:
c + b – b = (d/a) - b
c = (d/a) – b

A company manufactures and sells shirts. The daily profit the company makes depends on how many shirts they sell. The profit, in dollars, when the company sells xx shirts can be found using the function f(x) = 6x - 70. Find and interpret the given function values and determine an appropriate domain for the function.
The numeric values of the function are given as follows:
f(-2) = -82, meaning that if the company sells -2 shirts, it would have a profit of -82 dollars. This interpretation does not make sense in the context of the problem.f(12) = 2, meaning that if the company sells 12 shirts, it would have a profit of 2 dollars. This interpretation makes sense in the context of the problem.f(17.5) = 35, meaning that if the company sells 17.5 shirts, it would have a profit of 36 dollars. This interpretation does not make sense in the context of the problem.An appropriate domain for the situation is of:
{x ∈ N | x ≥ 0.}
What are the numeric values of the function?The function in this problem is defined as follows:
f(x) = 6x - 70.
In which the variables are given as follows:
x is the number of shirts sold.f(x) is the profit when x shirts are sold.Hence when x = -2, the numeric value is given as follows:
f(-2) = 6(-2) - 70 = -82.
This point is outside of the domain, as the number of shirts cannot be negative, hence an appropriate domain for the function is of:
{x ∈ N | x ≥ 0.}
As the number of shirts is also a countable amount.
When x = 12, the numeric value is given as follows:
f(12) = 6(12) - 70 = 72 - 70 = 2.
When x = 17.5, the numeric value is given as follows:
f(17.5) = 6(17.5) - 70 = 35.

9) John and Sarah are each saving money for a car. The total amount of money John will
save is given by the function J = 28 + 4x.
The total amount Sarah will save is given
by the function S = x2 + 2x + 20. After
how many weeks, x, will they have the same amount of money saved? Explain how you arrived at your answer.
To find out how many weeks it will take for John and Sarah to save the same amount of money, we must set their respective functions equal to each other and solve for x.
J = S
28 + 4x = x2 + 2x + 20
x2 + 2x - 4x - 8 = 0
x2 - 2x - 8 = 0
(x - 4)(x + 2) = 0
x = 4 or x = -2
Since x must be a positive value, the answer is that it will take John and Sarah 4 weeks to have the same amount of money saved.

Rank the population sizes (N) from fastest to slowest growth. If two population sizes have the same growth, overlap them.
The rank of population size from fastest to slowest growth is N = 1250, N = 1500, N = 1000, N = 750, N = 500, and N = 250.
The population growth rate is the measure that helps to determine how much the population size changes over time. The population growth rate shows either logistic growth or exponential growth. The formula for logistic population growth is given by [tex]\frac{dN}{dt}=r_{\text{max}}N\left(\frac{K-N}{N}\right)[/tex]. Here, N is the population size, t is time, r (max) is the maximum rate of increase, and K is the carrying capacity.
The one that grows fast will have a large population size, and the one that grows slowly will have a small population size. To rank the population size, arrange the given population size from the largest to the smallest. As a result, we get,
Fastest growth rate N=1250, N=1500 , N=1000, N= 750, N= 500, N= 250 Slowest growth rate

on a certain transatlantic crossing, 20 percent of a ship's passengers held round-trip tickets and also took their cars aboard the ship. if 60 percent of the passengers with round-trip tickets did not take their cars aboard the ship, what percent of the ship's passengers held round-trip tickets?
The percent of the ship's passengers held round-trip tickets is 50/100 = 50%.
Since the number of passengers on the ship is immaterial, let the number of passengers on the ship be 100 for convenience.
Let x be the number of passengers that held round-trip tickets.
Then, since 20 percent of the passengers held a round-trip ticket and took their cars aboard the ship, 0.20(100) = 20 passengers held round-trip tickets and took their cars aboard the ship.
The remaining passengers with round-trip tickets did not take their cars aboard, and they represent 0.6x (that is, 60 percent of the passengers with round-trip tickets).
Thus, 0.6x + 20 = x, from which it follows that 20 = 0.4x, and so x = 50.
The percent of passengers with round-trip tickets is, then, 50/100 = 50%

We can expect to find 185 defective fuses each day.
The correct answer is c) 185.
At first we have to find the expected number of defective fuses each day, we can use the formula for the expected value of a binomial distribution:
Expected Value (μ) = n * p
where:
n = number of trials (in this case, the number of fuses produced each day) = 500
p = probability of success (in this case, the probability that a fuse is defective) = 37/100 = 0.37
Expected Value (μ) = 500 * 0.37 = 185
So, we can expect to find 185 defective fuses each day.

The smallest possible value of c is 1 in this case.
If the integer a, b and c are in arithmetic progression.
Then we can write,
b = (a+c)/2
If the integer a, b and c are in geometric progression,
Then, we can write,
b = √(ac)
Now, we can write,
a+b = 2√(ac)
Squaring both sides,
a²+c²+2ac = 4ac
(a-c)² = 0
So,
a = c.
If a = c.
Then,
b = (a+a)/2
b = a
So, a = b = c.

For this graph, determine whether x and y are proportional.
If x and y are proportional, fill in the blank with a number in simplest form.
Answer:
Proportional
y is 0.4 times x
or
y is 2/5 times x
Both numbers are the same, I don't know which form the computer expects you to enter
Step-by-step explanation:
x and y are proportional since there is a linear relationship between y and x.
Let's verify this
When x = 5, y = 2. So y/x = 2/5 = 0.4
So y = 0.4x
When x = 10, y = 4
So y/x = 4/10 = 2/5 = 0.4
Again y = 0.4x
So the answer is 0.4, same as 2/5
Answer:
Step-by-step explanation:
the x and y are proportional because the number increases by the same number each time. so y =2 and x=5 then on the next one, if it's proportional, y will = 4 and x will = 10. another way you can be sure that it is proportional is that every time you add the first number you can divide it and get the first number. for example if you divide 4 by 2 you will get 2. if you divide 10 by 2 you get 10. so in a short answer yes it is proportional
