A graph of the linear function (y = 2x - 3) which matches the answer is shown in the image attached below.

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.

The general slope intercept form equation of a line is as stated below;

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;

Substituting the above values, we'll have

Let's open up the parenthesis first, we'll have;

Let's isolate y by adding 7 to both sides of the equation;

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).

Step-by-step explanation:

I don't see any statements either.

anyway, the only thing that can be said about the 2 lines is that they are crossing each other at one point.

the lines are not parallel, they are not perpendicular (90° to each other), they are not identical.

nothing can be said about a specific point on the line of intercepts with the x- and y-axis.

they are also not parallel and not perpendicular to any of the x- or y-axis.

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.)

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:

Let 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]

Divide the numerator and the denominator by the highest common factor:

[tex]\implies \dfrac{5 \div 5}{10 \div 5}=\dfrac{1}{2}[/tex]

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.

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.

f is the given profit function whose input is number of cones and output is profit, f(50)=80 tells that $80 profit is made by selling 50 cones of ice cream.

A function is a relation that assigns each element of a set a unique element of another set.

f(x) denotes that function f works on the input values x and give output f(x).

If f is a function and f(x) = x+2, then if we have to check x= 1 , then

f(1) = 1+2 = 3 is the value of the function f at x=1

A La Mode Ice Cream Parlor uses a function f as profit function

The input x is the number of cones it sells and output is profit

f(50) = 85

⇒x = 50 and f(50) = 85

It means that when the parlor sells x = 50 cones , it makes  profit $ f(50) = 85

The function operation ( f + g )( x ) in the functions f( x ) = x² + 2x and g( x ) = 4x² - 3 is 5x² + 2x  - 3.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

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 )

Remove the parenthesis

( f + g )( x ) = x² + 2x + 4x² - 3

Collect and add like terms

( f + g )( x ) = x² + 4x² + 2x  - 3

( f + g )( x ) = 5x² + 2x  - 3

Answer: See explanation

Step-by-step explanation:

For questions 1 - 4, it's asking you to plug in numbers into the original functions.

1. f(-2): You would plug -2 into f(x) = 2x^2 - 3x, getting

2(-2)^2 - 3(-2)

2(4) - (-6)

8 + 6 = 14

f(-2) = 14

2. f(x) - g(x): You're basically just subtracting the two functions

(2x^2 - 3x) - (2 - 5x)

2x^2 - 3x - 2 + 5x

Combine like terms

2x^2 + 2x - 2

3. You're multiplying them so (2x^2 - 3x)(2 - 5x)

4. f(g(x)): It's like f(-2), but instead of -2, you plug in the function of g(x)

So in 2x^2 - 3x, x would equal 2 - 5x:

2(2 - 5x)^2 - 3(2 - 5x)

And then simplify that.

For questions 5 - 6, it's asking for shifting from the parent function. Parent function is always f(x) or g(x) or whatever variable it is.

5. f(x - 8) + 9: The 9 is the y value shift, meaning the parent function is shifted up 9 units. For -8, think of what x needs to be for (x - 8) to be 0. If that number is positive, function shifts right; if negative, shift left. In this case, x needs to be 8 in order for (x - 8) to be 0. Therefore, f(x) is shifted right 8 units.

6. -3f(x) - 2: From the previous question, we now know that -2 means f(x) is shifted down 2 units. When you have 3f(x), you're multiplying the entire function by 3, so it's called a vertical stretch of 3. The negative means it's reflected over the x-axis since the y value is the opposite of what it used to be.

The measure of x is found as 22 for the given vertically opposite angles.

For the given question;

5x + 4 = 114 (As both lines intersecting and vertical angles are formed).

Solving the equation;

5x = 114 - 4

5x = 110

x = 22

Thus, the measure of x is found as 22.
