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.

Applying the linear pair postulate, m<SQR = 74°.
What is the Linear pair Postulate?According to the linear pair postulate, the equation below is holds true:
m<TQS + m<SQR = 180.
m<TQS = (3m + 1)°
m<SQR = (2m + 4)°
Substitute the values
(3m + 1) + (2m + 4) = 180
Solve for m
3m + 1 + 2m + 4 = 180
Add like terms
3m + 2m + 1 + 4 = 180
5m + 5 = 180
Subtract 5 from both sides of the equation
5m + 5 - 5 = 180 - 5
5m = 175
m = 35
m<SQR = (2m + 4)° = 2(35) + 4 = 74°.

Answer:
x = 0
Step-by-step explanation:
Given equation,
→ 2(3x - 1) + 2(4x + 5) = 8
Now the value of x will be,
→ 2(3x - 1) + 2(4x + 5) = 8
→ 6x - 2 + 8x + 10 = 8
→ 14x + 8 = 8
→ 14x = 8 - 8
→ x = 0/14
→ [ x = 0 ]
Hence, the value of x is 0.
The function m(x) = |x-441 represents the absolute deviation (in years) of a man's agex (in years) from the average age of men in a

A
The age of the man is years from the average age of men in the city. The age of the woman isyears from the average age of women in the city.
the absolute deviation for the man is 3 years more than the one for the woman.
How to compare the deviations?We know that the absolute value function:
m(x) = |x - 44|
Represents the absolute deviation of man's age, in years.
This means that the average age of a man in that city is 44 years old, so if a man has 64 years, then the absolute deviation is given by:
m(64) = |64 - 44| = 20
The absolute deviation for a man of 64 years old living in this city is 20 years.
Similar for the case of women, the equation here is:
w(x) = |x - 47|
If a woman has 64 years old, then the absolute deviation is:
w(64) = |64 - 47| = 17
The absolute deviation is 17 years.
We can see that the absolute deviation for the man is 3 years more than the one for the woman.

Answer:
x = 34
Step-by-step explanation:
1/4(x - 2) + 4 = 12
Subtract 4 from both sides.
1/4(x - 2) = 8
Multiply both sides by 4.
x - 2 = 32
Add 2 to both sides.
x = 34

Convert 4 to the fraction 8/2.[tex]\bf{\dfrac{1}{4}x-\dfrac{1}{2}+\dfrac{8}{2} =12 }[/tex]

Convert 12 to the fraction 24/2.[tex]\bf{\dfrac{1}{4}x=\dfrac{24}{2}-\dfrac{7}{2} }[/tex]

What is the short definition of a coordinate plane?
Two number lines combine to generate the two-dimensional surface known as the coordinate plane. The x-axis is a single horizontal number line. The y-axis is the name of the vertical number line that is the other number line. The origin is where the two axes come together. The coordinate plane can be used to graph points, lines, and other things.For point (x1,y1) and (x2,y2) on coordinate plane if m is the midpoint of these points, then coordinate of mid point is given by
(x1+x2)/2, (y1+y2)/ 2
Given point
B= (-5,1)
M = (-3,3)
we have to find point A, let it be (x,y)
using the above formula , midpoint m is

W'X' is parallel to W'Z'

The reflection transformation of the given diagram means that; W' X' is parallel to Z' Y'
How to Interpret Transformation Reflection?
Reflection over y-axis is a reflection or flip over the y-axis where the y-axis is the line of reflection used. The formula for this is: (x,y) →(−x,y) ( x , y ) → ( − x , y ) .
To reflect an equation over the y-axis, simply multiply the input variable by -1: y=f(x)→y=f(−x) y = f ( x ) → y = f ( − x )

Express the mass of 49,000 molecules of oxygen in scientific notation.
grams
The scientific notation for the mass of 49,000 molecules of oxygen is 4.9 × 10⁴ grams.
How do you define the scientific notation?To transform numbers into scientific notation, use the following rule: In scientific notation, the exponent equals the number of times the decimal point must always be shifted to produce a number between 1 and 10.
The proper scientific notation format is an x 10∧b, where an is a number or decimal number with an absolute value greater or equal to one and less than ten, or 1 |a| 10.Scientific notation is a method of writing extremely large or extremely small numbers in a way that makes them easier to read as well as work with. A number formed by multiplying a number greater or equal to one but less than ten by an integral power of ten.For the given value;
= 49,000 grams
write the number such that only one digit is left to the left of decimal of the number and the remaining digits to the write are written to the power of 10
= 4.9000 × 10⁴
This could be written as;
= 4.9 × 10⁴.
Therefore, the value of the mass of 49,000 oxygen molecules in the form of scientific notation is 4.9 × 10⁴ grams.

What is defined as the section formula?The Section formula is used in coordinate geometry to find the ratio of a line segment divided by a point, either internally or externally. It determines the centroid, incenter, and excenters of a triangle.Let P be the point that is 3/10 of a way from A to B. This means that it divides P in the ratio 3:10 = AP/PB = 3/10.
To find the coordinates, use the internal division formula, which is given as:
x = (mx₂ + nx₁)/(m + n)
y = (my₂ + ny₁)/(m + n)
Where,
(x₁, y₁) = A(-3, -5)
(x₂, y₂) = B(12, 4)
m = 3 and n = 10.
Substitute the values to find the x and y coordinates of point P.
y = (3×4 + 10(-5))/(3 +10)
On solving;
y = -19/15
Solve for x coordinates;
y = (3(12) + 10(-3)/(3 +10)
