The equation for DE is [tex]8+9x[/tex]
According to the question statement, Line RQ bisects line DE at S. If DS = 10 + 3x and ES = -2 + 6x. We are supposed to find DE.
For solving this we need to know about Linear Equations and Bisector of a line.
Given that, DS = 10 + 3x and ES = -2 + 6x.
S is mid point of line DE as RQ bisects it.
So DS = SE
And DE = DS + SE
Hence, DE = [tex]10 + 3x + (-2 + 6x)[/tex]
DE = [tex]10 + 3x -2 + 6x[/tex]
DE = [tex]10 -2 +3x+6x[/tex]
DE = [tex]8+9x[/tex]
Hence equation of DE is 8+9x.

Give me the integer value for Y on x+y=8
Answer:
5
Step-by-step explanation:
To find a value for y given a value for x, substitute the x-value into the expression
Answer:
Step-by-step explanation:
x + y = 8
Let x = 2
then:
2 + y = 8
y = 8 - 2
y = 6.
This is one integer value for y.
Consider any subset of the real numbers that consists only
of negative numbers. What can you conclude about whether the set is closed
under multiplication?
Explain.
Answer: Not closed under multiplication
====================================================
Explanation:
Pick any two negative numbers that you want.
I'll go for -3 and -5
They multiply to (-3)*(-5) = 15 which is a positive number. The two negatives cancel out to form a positive.
This is an example to show that multiplication is not closed for this subset of the real numbers. We consider it to be closed if the result of any two negative numbers multiplied would get us some other negative number.
In a sense, this is the complete opposite of closed since the result is never negative.
Here's an example of a set that is closed under multiplication: integers
Picking any two integers and multiplying them together gets us some other integer. Each item is found in the same set, i.e. the result never leaves or goes outside the set.

Same thing with y -4+1=-3 then -3/2=-1.5
So the answer is (5,-1.5)

an attorney charges a fixed fee for an initial meeting and an hourly fee for all hours worked after this meeting. the attorney charges $850 for an initial meeting and $250 per hour. which equation represents the relationship between h, the number of hours, and c, the total cost?
The equation which represents the relationship between 'h' the number of hours, and c, the total cost is y = 250x+850.
How to write equation of straight line?A straight line equation is a mathematical equation that describes the relationship between the coordinate points on that straight line. It can be written in several ways and indicates the slope, x-intercept, & y-intercept of a line.
A straight line's general equation is y = mx + c, in which m is the gradient and y = c is the value at which the line intersects the y-axis. The above number c is known as the y-axis intercept. A straight line with gradient m as well as intercept c on the y-axis has the equation y = mx + c.Now, as per the given question;
The attorney charges price for an initial meeting = $850.
And, the charges for each hour is = $250.
Thus, the equation which shows the given situation is-
y = 250x + 850.
In which, 250 is the value of the slope 'm'.
The y- intercept is shown by 850.
Thus, the total cost will be found out by equation y = 250x+850.

Given m(x) = |2x - 91, find x when m(x) = 15.
The value modulus functions of x are found as 12 and -3.
What is defined as the modulus functions?A modulus function returns the magnitude of a number regardless of its sign.
It's also known as the absolute value function. The modulus function, signified by |x| in mathematics, gives the modulus of a real number x. It returns a non-negative value for x. The modulus or absolute value of the a number is often recognized as the number's distance from the origin or zero.The modulus function's value is always non-negative. Whenever f(x) is a modulus function, we get:
For x is positive, then f(x) = xFor x = 0, then f(x) = 0For x < 0, then f(x) = -xfor the given function;
m(x) = |2x - 9|, where m(x) = 15.
then,
15 = |2x - 9|
Open the modulus function in its corresponding positive and negative values;
15 = 2x -9 and also 15 = -(2x - 9).
Solving both;
15 = 2x -9
2x = 15 + 9
2x = 24
x = 12
and, the second functions;
15 = -(2x - 9)
15 = -2x + 9
-2x = 15 - 9
x = -3
Thus, the solution for x are 12 and -3.

A cylindrical can has a radius of 4 centimeters. Write the volume V of the can as a function of the height h.
The volume of cylinder V as a function of the height h is: V = 50.24h
In this question, we have been given the radius of the cylinder which is 4 centimeters.
We need to write the volume V of the can as a function of the height h.
We know that, the formula of volume of the cylinder of radius r and height h is, V = π × r² × h
In this question, r = 4 centimeters
Substitute r = 4 in above formula of volume of cylinder.
⇒ V = π × r² × h
⇒ V = π × 4² × h
⇒ V = 3.14 × 16 × h
⇒ V = 50.24 × h
⇒ V = 50.24h

The obtained two numbers by substitution method are 5 and 12.
What is substitution method?The algebraic method for solving simultaneous linear equations is the substitution method.
The value of one variable through one equation is substituted in the second equation, as the name implies.To verify an equation system by substitution, enter your x and y values into the initial equations. Your answer is accurate if both simplification expressions are true.Let the first number be 'x'.
Let the second number be 'y'
From the given condition that second number is 3 times 1 less than the first number.
That is;
y = 3(x - 1)
Now the sum of both number are given as 17.
x + y = 17.
Use substitution method, and put the value of y in the total sum.
x + y = 17.
x + 3(x - 1) = 17
Simplify the given equation;
x + 3x - 3 = 17
4x = 17 + 3
4x = 20
x = 5 (first number)
Put the value of x in y to find the value.

Work out how much money Sarah has left.
You must show all your working.
After spending the money on oranges and apple, Sarah is left with 20p.
What is defined as the cost of the product?In mathematics, a product is described as the result of multiplying two or several numbers together.Product cost makes reference to the expenses incurred in the production of a product.As per the given question;
Sarah spend the amount to buy the 3 oranges is 30p each.
Total spending on oranges = 3 x 30p = 90p.
For buying 1/2 kg of apple; Sarah spend the amount of £1.20 per kg.
Cost for half kg of apples = 60p.
Total cost = apple + oranges
Total cost = 60p + 30p = 90p.
Total cost = £1.50
Now, the only money Sarah has is one 50p coin and six 20p coins.
Sarah' money = 50p + (6 x 20)p
Sarah' money = 50p + £1.20
Sarah' money = £1.70
Money left = £1.70 - £1.50
