The sum of 6 consecutive integers is 339.
Answer:
54, 55, 56, 57, 58, and 59 are the numbers
Step-by-step explanation:
Let's pretend that the first number is [tex]n[/tex].
We know that these numbers are consecutive, meaning each number is one more than the other.
This means that
[tex]n + (n+1)+ (n+2)+ (n+3)+ (n+4)+ (n+5) = 339[/tex], since each number is consecutive.
We can combine like terms to get [tex]6n + 15 = 339[/tex].
Now let's solve for n.
[tex]6n + 15 - 15 = 339-15\\\\6n = 324\\\\n = 54[/tex]
So [tex]n=54[/tex]. This means the other 5 digits will be one more than the next.
So 54, 55, 56, 57, 58, and 59.

Solve for :
-18.43 = 3.99 + x
Answer: [tex]x=-22.42[/tex]
Simplify both sides of the equation
[tex]-18.43=x+3.99[/tex]
Flip the equation
[tex]x+3.99=-18.43[/tex]
Subtract 3.99 from both sides
[tex]x+3.99-3.99=-18.43-3.99\\x=-22.42[/tex]

The solution set for this inequality is {x | x > 2}
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We also find the solution in a system of equations using the substitution or elimination method.
Example:
2x + 4 = 8
The solution is x = 2.
We have,
To solve the inequality:
2x - 3 > 11 - 5x
We can start by simplifying the expression on both sides:
2x - 3 > 11 - 5x
Adding 5x to both sides
7x - 3 > 11
Adding 3 to both sides
7x > 14
Dividing both sides by 7
x > 2
This means that any value of x greater than 2 will make the inequality true.
Thus,
The solution set for this inequality is {x | x > 2}

What is the value of x in the equation?
Answer:
[tex]x=56[/tex]
Step-by-step explanation:
So we have the equation:
[tex]\frac{2(x+4)}{3}-8=32[/tex]
First, add 8 to both sides. The left cancels:
[tex]\frac{2(x+4)}{3}=40[/tex]
Multiply both sides by 3. The left cancels:
[tex]2(x+4)=120[/tex]
Divide both sides by 2:
[tex]x+4=60[/tex]
Subtract 4 from both sides:
[tex]x=56[/tex]
And we are done!

what is the constant of the polynomial 2x3 - 8x2 + 3x - 7
Answer:
-7
Step-by-step explanation:
A constant number is a number that contains no variables like x and y. The only constant in that problem is -7.
A constant is a number which independent of anything and never changes thus the constant in the given expression 2x³ - 8x² + 3x - 7 is -7.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
As per the given expression,
2x³ - 8x² + 3x - 7
Here, x is a variable.
The constant multiplied by a variable is said to be the coefficient.
Thus, 2,-8,3 are the coefficient.
A number independent constant is -7 will be constant.
Hence "A constant is a number which is independent of anything and never changes thus the constant in the given expression 2x³ - 8x² + 3x - 7 is -7."

In each problem 7 through 14, verify that each given function is a solution of the differential equation. Y" - y = 0; y1(t) = et, y2(t) = cosh t.
Answer:
Since L.H.S = R.H.S = 0, for both [tex]y_{1} (t) = e^{t}[/tex] and [tex]y_{2} (t) = cosh(t)[/tex], y₁ and y₂ both satisfy the equation y" - y = 0 and are thus solutions to the differential equation.
Step-by-step explanation:
To check whether the given functions are solutions the given differential equation, we differentiate the functions and then insert it into the given equation.
So y" - y = 0 and
[tex]y_{1} (t) = e^{t}\\y_{1}' (t) = e^{t}\\ y_{1}" (t) = e^{t}[/tex]
Substituting these values of y and y" into the left hand side of the equation, we have
y" - y
[tex]y_{1}" (t) - y_{1} (t) = e^{t} - e^{t} = 0[/tex]
Since L.H.S = R.H.S
So [tex]y_{1} (t) = e^{t}[/tex] is a solution of the differential equation.
When
[tex]y_{2} (t) = cosh(t)\\ y_{2}'(t) = sinh(t) \\y_{2}"(t) = cosh(t)[/tex]
Substituting y and y" into the left hand side of the equation, we have
y" - y
[tex]y_{2}"(t) - y_{2} (t) = cosh(t) - cosh(t) = 0[/tex]
Since L.H.S = R.H.S
So, [tex]y_{2} (t) = cosh(t)[/tex] is a solution of the differential equation.

3. A drone takes off from the base of a mountain at a height of 27 ft below sea level. The drone
then flies up 642 ft before landing at the top of the mountain. How tall is the mountain?
Answer:
669ft high
Step-by-step explanation:
642+27=669ft
The height of the mountain is 669 ft.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
For example 4 -2 = 2
A drone takes off from the base of a mountain at a height of 27 ft below sea level.
To determine the height of the mountain.
Using the arithmetic operations of addition and subtraction,
The drone then flies up 642 ft before landing at the top of the mountain.
Assume that distance below sea level is positive,
So the height of the mountain as
⇒ 642 + 27
⇒ 669 ft
Hence, the height of the mountain is 669 ft.

largest to smallest 4 3/5 -17 3/5 -14 5/5
Answer:
4 3/5, -14 5/5, -17 3/5
Step-by-step explanation:
Timothy has three friends. The following table shows the distance and time it takes him to drive to each of his friends’ houses. 5 km 11 km 18 km to 10 min 15 min 20 min. Is the time it takes Timothy to drive to his friends’ houses proportional to the distance
Answer:
No
Step-by-step explanation:
The time it takes Timothy to drive to his friends' houses is not proportional. This is because when going to the first house, he is going at 4km per minute, but when visiting the second and third houses he is no longer traveling at that speed.
In a directly proportional relationship, increasing one variable will increase another. The given relationship is not proportional.
What is the directly proportional and inversely proportional relationship?In a directly proportional relationship, increasing one variable will increase another.
This directly proportional relationship between p and q is written as
p∝q where that middle sign is the sign of proportionality.
Inversely proportional relationship increasing one variable will decrease the other variable if both are inversely proportional.
This directly proportional relationship between p and q is written as
p∝1/q where that middle sign is the sign of proportionality.
Given that the table shows the distance and time it takes him to drive to each of his friends’ houses.
Now, to know if the time it takes Timothy to drive to his friends’ houses proportional to the distance, find the ratio of distance to time for each row. Therefore, the ratios can be written as,
R₁ = 5km / 10 min = 0.5 km per min
R₂ = 11 km / 15 min = 0.7334 km per min
R₃ = 18 km / 20 min = 0.9 km per min
Since the ratio of distance and time in different cases is different, therefore, the given relationship is not proportional.

What is the point-slope form given the following slope and a point on the line? m = 3/7 , (7, -4)
Answer:
The equation is y = (3/7)x - 7.
Step-by-step explanation:
Given that the point slope form of an equation is y = mx + b where m represents the gradient and b is the y-intercept. Then, you have to substitute the following values into the equation :
[tex]y = mx + b[/tex]
[tex]let \: m = \frac{3}{7} ,x = 7,y = - 4[/tex]
[tex] - 4 = \frac{3}{7} (7) + b[/tex]
[tex] - 4 = 3 + b[/tex]

Is the sum of two binominals is always a binomial? Why or why not?
Answer:
No
Step-by-step explanation:
Algebraic Terms:
1. Monomial - an algebraic term
2. Binomial - the sum of 2 algebraic terms
3. Trinomial - an algebraic sum in 3 terms
4. Polynomial - a function in more than 1 algebraic term
The sum of 2 binomials is not always a binomial because each of the two binomials might have different algebraic terms.
If the first binomial has 2 algebraic terms and the second binomial has 2 other algebraic terms and no single term crosses out its coefficients, the sum of both binomials will not be a binomial.
