The tables show a Linear function that represents your earnings y in dollars after x working hours
(Picture below)
What is the totals earnings for the 6th hour?
$
What is your hourly wage?
$
Answers
Answer:
total earnings at 6th hour: 111
hourly wage (slope): 18.5
Step-by-step explanation:
A linear function has a linear relationship, which essentially states as x increases by one, the y-value increases by some constant amount yielding a straight line.
The slope, or how much the y-value changes as x changes by 1 is generally written as: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can choose any two points and this should yield the slope of the function, but it's a lot easier to choose y-values that are only separated by an x-value of one.
Let's say: [tex](x_1, y_1)=(4,\ 74)\text{ and }(x_2,y_2)=(5,\ 92.50)[/tex]
If we plug the values into the slope formula we just get: [tex]\frac{92.50-74}{5-4}=\frac{92.50-74}{1}=92.50-74[/tex]
And this makes sense, since by definition of a slope, it's just the change in y over change in x. This is equivalent to how much the y-value changes as x increases by one, so if we select two values with a difference of one in their x-values, the slope just turns out to be the difference between the two numbers.
Simplifying our expression we get: [tex]92.50-74=18.5[/tex]
This slope in this context represents how earnings increases as the hour increases, or in other words the hourly wage.
To calculate the earnings of the 6th hour we can just use the definition of a slope. From the x-value 5 to the x-value 6, the y-value should simply increase 18.5
So adding 18.5 to the y-value at x=5 we get: [tex]92.5+18.5=111[/tex]

The system of Inequality for the given graph is;
2x + 3y ≥ 12
3x - 5y ≥ 15
How to Interpret Inequality graph?
Inequalities that use < or > symbols are always plotted with a dashed line while Inequalities that use ≤ or ≥ symbols are always plotted with a solid line.
Now, if the shaded portion is above a dashed line, the the symbol is > but if it is shaded above a solid line, then the symbol is ≥. In this question, a solid line is used for both equations and shaded above the lines and so we will use ≥.
Equation of Line 1;
x-intercept = 6
y intercept = 4
Slope = -2/3
Thus, using the general equation of slope of line, the equation of this inequality is; 2x + 3y ≥ 12

The probability that the first applicant with advanced training in programming is found on the third interview is 0.0469
Let X denote the number interviewed until 1 has advanced training and follows a geometric distribution with parameter 75%, so

The density function of geometric distribution is,

From the given linear equation graph, we can tell that the equation of the line in slope intercept form is; y = 1.2x + 3
How to Interpret Linear Equation Graph?
The general form of equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
From the given graph, we see that;
y - intercept = 3
x - intercept = -2.5
Now, we can find the slope by taking two coordinates;
(-2.5, 0) and (0, 3)
Slope = (3 - 0)/(0 - (-2.5))
Slope = 3/2.5
Slope = 1.2

Ellie needs 1.5 gallon of milk (that is 24 cups).
we are given 2 cup = 1 pint
we have 24 cup which will be equal to 24/2 i.e. 12 pint.
we are given 2 pint = 1 quart
we have 12 pint which will be equal to 12/2 i.e. 6 quart

The rational equivalent to 0.86 can be written as 43/50.
A rational number may be defined as the number which can be expressed in the form of p/q where p and q are integers, and the term q cannot be equal to zero. It can be either positive or negative or both. We can also say that any fraction which does not have zero in the denominator is called a rational number. Zero can also be regarded as a rational number as it can also be represented as a fraction. For example, 0/2, 0/5. In order to write 0.86 as a rational number, we have to convert it in fraction form. In fraction form it can be written as

Solve for x -
[tex]\sf 6+4x+3=6x-21[/tex]
Answers
Answer:
x = 15
Step-by-step explanation:
Let's start by copying down the equation.
6 + 4x + 3 = 6x - 21
Let's simplify this equation and we get,
4x + 9 = 6x - 21
Now, we can add 21 to both sides to isolate 6x on one side. Then, we get...
4x + 30 = 6x
Now, we minus 4x from both sides to get rid of it.
Then we get...
2x = 30
Thus, x = 15
6 + 4x + 3 = 6x - 21
We minus (4x+3) on both side.
6 + 4x + 3 - (4x+3) = 6x - 21 - (4x + 3)
6 = 2x - 24
2x = 30
x = 15.
Recheck : 6 + 60 + 3 = 90 - 21

A construction crew is lengthening a road. The road started with a length of 53 miles, and the crew is adding 4 miles to the road each day.
Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked.
Write an equation relating L to D. Then use this equation to find the total length of the road after the crew has worked 36 days.
Answers
Answer:
L = 4D + 53
After 36 days of work, the road will be 197 miles long.
Step-by-step explanation:
This question requests that an equation is found to represent the relationship between the length of a road and the days that the workers spend working on the road.
We are given that the road is 53 miles long prior to the work done by the construction crew. This means that this will be added in addition to what we will find.
L represents the length of the road after D days. Since the road is lengthened by 4 miles each day, this could be represented by 4 * D, or simply 4D.
Therefore, the equation we find can be written as L = 4D + 53.
Since we need to find how many miles the road will be after 36 days of work, substitute 36 days as D and solve for L:
L = 4(36) + 53
L = 144 + 53
L = 197
Therefore, the road will be 197 miles long after 36 days of construction.

Find the solutions to x² = 12. O A. x = +2√/6 OB. x = +2√3 O C. x = +6√2 O D. x = ±3√2
Answers
The solution for the expression x² = 12 will be x = ±2√3.
The expression is given in the form of square of a variable x which is equal to 12. This expression does not form a perfect square as the constant term is not a perfect square number. A perfect square is a number which is expressed as the square of whole number, or a number multiplied by itself twice. Here, we are given that x² = 12. We take square root of the expression on both the sides then,
√x² = √12
x = √(2×2×3)
x = ±2√3
We use the sign '±' because any number which when expressed in variable form comes out of the square root then it can be positive or negative,
Thus, the value of x is ±2√3.

A) $46.49
B) $46.72
C) $29.41
D) $45.16
Answers
Answer:
B) $46.72
Step-by-step explanation:
Let j = cost of the jeans
j * 1.07 is the cost of the jeans with tax
j * 1.07 = 49.99
Divide each side by 1.07
j * 1.07 /1.07 = 49.99 / 1.07
j =46.72
The jeans can cost no more than 46.72
Answer:
B) $46.72
Step-by-step explanation:
The problem can be expressed as an equation you solve for "y"
y + y * 0.07 = 49.99
We factor out the "y" from the equation and we get
y * (1 + 0.07) = 49.99
Which is the same as
y * 1.07 = 49.99
We can then divide by 1.07 both sides
y = 49.99 / 1.07
Which yields
y = 46.719

Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.
Given that a line's equation is,
y = 8 / 9x - 7
If we contrast this equation with a line's slope-intercept,
this line's slope = 8/9
Since every line parallel to this one will have a same slope,
The parallel line's slope is equal to
The symbol for the line with the slope 'm' and the coordinates (x', y') is
y - y' = m(x - x')
As a result, the equation of the line through (-1, 8) with a slope will be,

y =8/9x - 8/9 - 8
