The system of equations below models the cost and revenue for Sean's outdoor yard games where x represents the number of games and y represents the amount, in dollars.
The break even point obtained for the Sean's business is (60/7, 5100/7).
How to describe the linear equation in two variables?A linear equation in 2 variables is one that is written in the form ax + by + c = 0, where a, b, and c are real numbers and thus the coefficients of x and y, i.e. a and b, are not equal to zero. For example, 12x+8y = 9 and -x+8y = 3 are two-variable linear equations.Part of the question is missing where x denotes a number of games and y denotes the monetary value.
y = 50x + 300
y = 85x
Estimate Sean's business's break-even point.
Calculate the same break even point by following method;
The functions are as follows:
The functions are given as:
Cost: y = 50x + 300 ......equation 1
Revenue: y = 85x .......equation 2
For the value at break even point;
Cost = Revenue
Thus, equating 1 and 2.
85x = 50x + 300
simplifying;
35x = 300
Dividing both sides by 35
x = 60/7
Put x = 60/7 in equation 2
y = 85 × 60/7
y = 5100/7
Therefore, the break even point are obtained as (60/7, 5100/7).

Step-by-step explanation:
Let the graph of g be a translation 4 units left followed by a horizontal shrink by a factor of 1/3 of the graph of f(x)=x²+x. Write a rule for g
The transformed function is:
g(x) = (3*(x + 4))² + (3*(x + 4))
How to write the transformed function?Here we have the function:
f(x) = x² + x
Now we want to apply a translation of 4 units to the left, followed by a horizontal shrink by a factor of 1/3.
First, the translation is written as:
g(x) = f(x + 4)
Now the shink will give:
g(x) = f( 3*(x + 4))
Replacing the actual function we will get:
g(x) = (3*(x + 4))² + (3*(x + 4))

find ∠rqt (4x+15) (10x-3)
The measure of angle RQT is 63°
Calculating anglesFrom the question, we are to determine the measure of angle RQT.
From the diagram,
We can observe that ∠PQS and ∠SQT form a linear pair
Thus,
∠PQS + ∠SQT = 180°
(4x + 15)° + (10x - 3)° = 180°
First, determine the value of x
4x + 15 + 10x - 3 = 180
4x + 10x = 180 - 15 + 3
14x = 168
x = 168/14
x = 12
In the diagram,
∠RQT and ∠PQS are vertically opposite
From the given information,
∠PQS = (4x + 15)°
∴ ∠RQT = (4x + 15)°
Substitute the value of x
∠RQT = (4(12) + 15)°
∠RQT = (48 + 15)°
∠RQT = 63°

how do u work out 1/2(2y+4)=-6
Answer:
The answer is y = -8
Step-by-step explanation:
You distribute,
1/2 x 2y = y
1/2 x 4 = 2
y+ 2 = -6
(then you subtract 2)
y=-8
If you would like to check, just put -8 into the equation in place of y
So it would look like this: 1/2(2 x -8 + 4) = -6

For a certain type of computers, the length of time between charges of the battery is normally distributed with a mean of 50 hours and a standard deviation of 15 hours. john owns one of these computers and wants to know the probability that the length of time will be between 50 and 70 hours? choose one.
The probability that the length of time will be between 50 and 70 hour is 0.4082.
What is normal distribution?Height is a simple instance of an event that describes a normal distribution: most people are of medium height, the proportions of people who are taller and shorter than average are roughly equal, and a very small (but still roughly equivalent) proportion of people either are extremely tall or extremely short.
Now, as per the given question;
Let t be the variable representing the length of time (t = 50)
As a result, the mean of the battery is 50 and the standard deviation is 15.
Thus, μ = 50 (mean) σ = 15 (standard deviation)
Now, we must calculate the probability that t is between 50 & 70.
Thus, the probability P (50 < t < 70)
The z-value will be calculated as;
Z = (t – μ) / σ
Substitute the values,
Z = 50 – 50 / 15
Z = 0
Now, for the time; t = 70
Z = 70 – 50 / 15
Z = 1.33
Thus, the probability is;
P(50 < t < 70) = P(0 < z < 1.33)
So, the area to left of Z
= 1.33 – area to the left of z = 0
= 0.9082 – 0.5
P(50 < t < 70) = 0.4082
Therefore, the probability that the length of time will be between 50 and 70 hours is 0.4082.

Find the 66th term of the arithmetic sequence -10, 7, 24, ...
========================================
Explanation:
[tex]a_1[/tex] = -10 is the first term
d = 17 is the common difference. We add this amount to each term to get the next one. Eg: -10+17 = 7
We want to find the 66th term, so we'll use n = 66
Plug these values into the nth term arithmetic sequence formula below.
[tex]a_n = a_1 + d(n-1)\\\\a_{66} = -10 + 17(66-1)\\\\a_{66} = 1095\\\\[/tex]

BODMAS is an acronym that stands for Bracket, Order, Division, Multiplication, Addition, Subtraction. In certain regions, a synonym for BODMAS is used: PEMDAS (parentheses, exponents, multiplication, division, addition, and subtraction). It describes the order of operations performed when solving an equation. According to the BODMAS rule, if an expression contains parentheses ((), {}, []), first break or simplify the parentheses, then "order" (meaning exponentiation, root, etc.), division, multiplication , addition and subtraction from the left.By using BODMAS , we will first simplify the bracket term.
The bracket term is [tex](3\times10-1)[/tex]
After , bracket we will operate the multiplication term which is given by

If a(x) = 3x + 1 and b(x) = √x-4, what is the domain of (bºa)(x)?
SOlution : Domain of (bºa)(x) = [4, ∞]
The term domain is most commonly used to describe the set of values D for which a function (map, transformation, etc.) is defined. For example, a function f(x) that is defined for real values x in R has domain R, and is sometimes said to be "a function over the reals." The set of values to which D is sent by the function is then called the range.
The domain (in its usual established mathematical sense) of a probability density function (and therefore also its distribution function) is available with the undocumented Wolfram Language command DistributionDomain[dist].
The meaning of "domain" in topology is a connected open set.
Another meaning of "domain" is what is more properly known as an integral domain, i.e., a ring that is commutative under multiplication, has an identity element, and no divisors of 0.
In the algebra of the function that is (f ± g)(x), (fg)(x) and (f/g)(x) the domain of the function will be an intersection of the domain of the functions f and g
Here the domain of the product of the function is asked thus the required domain will be an intersection of the domain of the function a and b.
Given a(x) = 3x + 1 ⇒ Domain, D1 = R
b(x) = √(x - 4) ⇒ Domain, D2 = [4, ∞]
Now, Domain of (b*a)(x) = Domain b(x) ⋂ Domain a(x)
= D2 ⋂ D1
= [4, ∞] ⋂ R
= [4, ∞]
Domain of (bºa)(x) = [4, ∞]
