On a piece of paper, Graph y = 2x-3. Then determine which answer matches the graph you drew.
A graph of the linear function (y = 2x - 3) which matches the answer is shown in the image attached below.
What is a graph?A graph refers a type of chart that's commonly used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
Generally speaking, the graph of any proportional relationship such as a linear function is characterized by a straight line with the points passing through the origin (0, 0) because as the values on the x-axis decreases or increases, the values on the y-axis decreases or increases simultaneously as shown in the image attached below.
In conclusion, a graph representing the given linear function shows a proportional relationship between the value of x and y.

Let c(t) be the number of customers in a restaurant t hours after 8am Explain the meaning of each statement please help
The meaning of each statement is shown below.
Step-by-step explanation:
Assume that the given statements are
(a) c(0)=0
(b) c(3)=c(8)
(c) c(n)=29
(d) c(13)<c(12)
Let c(t) be the number of customers in a restaurant t hours after 8 A.M.
We need to find the meaning of each given statement.
(a) c(0)=0 means the number of customers 0 hours after 8 A.M (i.e., 8 A.M.) is 0.
(b) c(3)=c(8) means the number of customers 3 hours after 8 A.M (i.e., 11 A.M.) is equal to the number of customers 8 hours after 8 A.M (i.e., 4 P.M.).
(c) c(n)=29 means the number of customers n hours after 8 A.M is 29.
(d) c(13)<c(12) means the number of customers 13 hours after 8 A.M (i.e., 9 P.M.) is less than the number of customers 12 hours after 8 A.M (i.e., 8 P.M.)

What is the function operation ( f + g )( x ) in the given function?A function is simply a relationship that maps one input to one output.
Given the data in the question;
f( x ) = x² + 2xg( x ) = 4x² - 3( f + g )( x ) = ?First, replace the function designators in f + g with actual functions.
( f + g )( x ) = ( f )(x) + ( g )( x )
( f + g )( x ) = ( x² + 2x ) + ( 4x² - 3 )

The two triangles above are similar. a. Find x using the ratio of the sides 12 cm and 16 cm: x/20=12/16. Show your work. b. Find x using the ratio of the sides 6 cm and 8 cm. Show your work. c. Explain why the answer to (a) and (b) should be the same.
a)
If the triangles are similar, the corresponding sides vary on the same proportion, so the ratios between the corresponding sides are equal.
For
[tex]\frac{x}{20}=\frac{12}{16}[/tex]To solve for x you have to multiply both sides of the expression by 20
[tex]\begin{gathered} \frac{20x}{20}=(\frac{12}{16})\cdot20 \\ x=(\frac{3}{4})\cdot20 \\ x=15 \end{gathered}[/tex]b)
Following the same logic, the ratio between x and 20 is the same as the ratio between 6 and 8
[tex]\frac{x}{20}=\frac{6}{8}[/tex]6/8 can be simplifies as 3/4. Then multiply both sides by 20 to determine the value of x.
[tex]\begin{gathered} \frac{x}{20}=\frac{6}{8} \\ 20\cdot\frac{x}{20}=(\frac{3}{4})\cdot20 \\ x=15 \end{gathered}[/tex]As mentioned above, when two triangles are similar, the corresponding sides are always in the same ratio, that is why the results in a and b are the same.

online. He records the number of models he
completes every couple of hours. The graph shows
Dan's data. Choose two pairs of points on the line
and calculate the slopes between them. Is Dan's
productivity constant? Explain.
The slope between the two pair of points is 3/2. Yes, Dan's productivity is constant.
Number of model are represented on y axis and the hours are represent on x axis.
As we can observe,
One pair of points on the graph is (4,6) and (2,3) and the other pair of points is (6,9) and (0,0)
The slope m between any two points (a,b) and (c,d) can be calculated as,
m = (d-b)/(c-a)
The two points we have are (4,6) and (2,3), so the slope M between them is,
M = (3-6)/(2-4)
M = -3/-2
M = 3/2.
And the slope M' between other two point (6,9) and (0,0) is,
M' = (9-0)/(6-0)
M' = 9/6
M' = 3/2.
As we can see, the slope is same. The slope represents the ratio of number of models and hours. We can conclude that Dan's productivity is constant.

Cynthia was offered two different jobs for the summer. Working as a camp counselor, she will earn $20 per hour plus an additional $25 bonus. Her earnings after x hours can be represented by the function f(x) = 20x + 25. Working as a lifeguard, Cynthia will earn $15 per hour and an additional $50 bonus. Her earnings after x hours can be represented by the function g(x) = 15x + 50. The arithmetic operation (f − g)x can be used to determine the difference in the salary Cynthia will earn working as a camp counselor instead of a lifeguard after x hours. What is the function (f − g)x?
The difference in the salary Cynthia will earn working as a camp counselor instead of a lifeguard after x hours (f − g)x = 5x - 25.
What is a function?A function can be defined as the set of inputs that results in output.
Given, Cynthia earns 20 dollars per hour working as a camp counselor plus an additional 25 dollars as a bonus which is f(x) = 20x + 25, and as a lifeguard 15dollars per hour and an additional 50 dollars bonus which is g(x) = 15x = 50.
We know (f - g)x = f(x) - g(x).
∴ The difference in the salary Cynthia will earn working as a camp counselor instead of a lifeguard after x hours is f(x) - g(x).
= (20x + 25) - (15x + 50).
= 20x - 15x + 25 - 50.

Plsss
[tex] \frac{5}{10} = what[/tex]
Answer:
The first questions unknown equals
[tex] \frac{3025}{49} [/tex]
The second question is unclear. I assume it is to simplify if that is the case the answer will be.
[tex] \frac{1}{2} [/tex]
Step-by-step explanation:
First Question I made ?=x for simplicity.
[tex]7 \sqrt{x} = 55[/tex]
then I divide both sides by 7
[tex] \sqrt{x} = \frac{55}{7} [/tex]
then I square both sides
[tex]x = \frac{3025}{49} [/tex]
Question 2
I simplified by dividing both the denominator and the numerator by their HCF (highest common factor) which is 5
[tex] \frac{5 \div 5}{10 \div 5} [/tex]
which equals
[tex] \frac{1}{2} [/tex]
Answer:
[tex]\textsf{1.} \quad 7\sqrt{\dfrac{3025}{49}}=55[/tex]
[tex]\textsf{2.} \quad \dfrac{5}{10}=\dfrac{1}{2}[/tex]
Step-by-step explanation:
Question 1Let x be the unknown number:
[tex]\implies 7\sqrt{x}=55[/tex]
Divide both sides of the equation by 7:
[tex]\implies \dfrac{7 \sqrt{x}}{7}=\dfrac{55}{7}[/tex]
[tex]\implies \sqrt{x}=\dfrac{55}{7}[/tex]
Square both sides of the equation:
[tex]\implies \left(\sqrt{x}\right)^2=\left(\dfrac{55}{7}\right)^2[/tex]
[tex]\implies x=\dfrac{55^2}{7^2}[/tex]
[tex]\implies x=\dfrac{3025}{49}[/tex]
Question 2Divide the numerator and the denominator by the highest common factor:
[tex]\implies \dfrac{5 \div 5}{10 \div 5}=\dfrac{1}{2}[/tex]
2. Write an equation in slope-intercept form of the line that passes through the point (-5, 7) and is perpendicular to the line y = 5x-1.
The general slope intercept form equation of a line is as stated below;
[tex]y=mx+b[/tex]where m is the slope and b is the intercept.
If we compare the given equation y = 5x-1 with the equation of a line, we can deduce that the slope, m, is 5.
The slope of a line perpendicular to another is always given as -1/m, therefore the line perpendicular to the line y=5x-1 will have a slope of -1/5;
So let's go ahead and substitute m= -1/5, into the point slope equation to determine the line that passes through (-5,7);
Remember, the point slope form equation of a line is given as;
[tex]y-y_1=m(x-x_{1)}[/tex]Substituting the above values, we'll have
[tex]y-7=-\frac{1}{5}(x+5)[/tex]Let's open up the parenthesis first, we'll have;
[tex]\begin{gathered} y-7=-\frac{1}{5}x-\frac{5}{5} \\ y-7=-\frac{1}{5}x-1 \end{gathered}[/tex]Let's isolate y by adding 7 to both sides of the equation;
[tex]y=-\frac{1}{5}x+6[/tex]The above equation is the required equation of the line in slope intercept form which can be compared to the one earlier written above(y = mx + b).

The diagram shows a rhombus inside a regular pentagon.
Work out the size of angle x.
The size of the angle x in the pentagon is 36 degrees.
How to find the angles in a pentagon?A regular pentagon is a polygon with five sides. The angles of a regular polygon is equal to each other.
Therefore,
the sum of angles in a regular pentagon = 540 degrees.
Each angle in a regular pentagon is 540 / 5 = 108 degrees.
The rhombus is inside the pentagon. Opposite angles in a rhombus are equal.
Therefore, the sum of interior angles of a rhombus adds up to 360 degrees
Hence,
108 + 108 + 2y = 360
where
y is the angle of the rhombus on the x variable.
Therefore,
2y = 360 - 216
2y = 144
y = 144 / 2
y = 72°
Therefore,
x = 108 - 72
