Given g(x) = 4x - 7, find g(-9)

Answer: A.

Step-by-step explanation:

Something is a function if the x value is not repeated. The y value can be repeated however.

The amplitude of the function y = sin 5лx is found as 1.

The sine (or cosine) function can be written as,

x = A sin (ωt + ϕ)   or   x = A cos (ωt + ϕ)

To find the variables used to calculate the amplitude, use the formula;

y = asin(bx - c) + d.

Where a is the amplitude.

The given equation of function is y = sin 5лx.

Comparing the function with the standard form

a = 1

Thus, the amplitude of the function y = sin 5лx is found as 1.

The inequality which represents the possible values for the number of peaches and mangos purchased will be;

⇒ $0.75p + $1.75m = $15

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Avni and her children went into a grocery store and will buy peaches and mangos.

Each peach costs $0.75 and each mango costs $1.75.

And, Avni has a total of $15 to spend on peaches and mangos.

Now,

Let number of peaches purchased = p

And, Number of Mangos purchased = m

Since, Each peach costs $0.75.

Hence, Total cost of peaches purchased = $0.75p

And, Each mango costs $1.75.

Hence, Total cost of mangos purchased = $1.75m

Since, Avani has a total of $15 to spend on peaches and mangos.

So, An inequality that would represent the possible values of peaches and mangos will be;

⇒ $0.75p + $1.75m = $15

Thus, The inequality which represents the possible values for the number of peaches and mangos purchased will be;

⇒ $0.75p + $1.75m = $15

[tex]\textsf{Slope-intercept form}: \quad y=-\dfrac{4}{3}x+\dfrac{5}{3}[/tex]

[tex]\textsf{Standard form}: \quad 4x+3y=5[/tex]

Step-by-step explanation:

Given linear equation:

[tex]y-11=-\dfrac{4}{3}(x+7)[/tex]

The given linear equation is point-slope form.

[tex]\boxed{\begin{minipage}{3.7cm}\underline{Slope-intercept form}\\\\$y=mx+b$\\\\where $m$ is the slope\\ and $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

To write the equation in slope-intercept form, isolate y:

[tex]\implies y-11=-\dfrac{4}{3}(x+7)[/tex]

[tex]\implies y-11=-\dfrac{4}{3}x-\dfrac{28}{3}[/tex]

[tex]\implies y-11+11=-\dfrac{4}{3}x-\dfrac{28}{3}+11[/tex]

[tex]\implies y=-\dfrac{4}{3}x+\dfrac{5}{3}[/tex]

[tex]\boxed{\begin{minipage}{5.4 cm}\underline{Standard form}\\\\$Ax+By=C$\\\\where $A, B$ and $C$ are constants and $A$ must be positive.\\\end{minipage}}[/tex]

To write the equation in standard form, eliminate the fraction, bring the terms in x and y to the left of the equation, and the constants to the right:

[tex]\implies y-11=-\dfrac{4}{3}(x+7)[/tex]

[tex]\implies (y-11) \cdot 3=-\dfrac{4}{3}(x+7) \cdot 3[/tex]

[tex]\implies 3y-33=-4(x+7)[/tex]

[tex]\implies 3y-33=-4x-28[/tex]

[tex]\implies 3y-33+4x=-4x-28+4x[/tex]

[tex]\implies 3y-33+4x=-28[/tex]

Value of the function [ f(x+ h) - f(x) ] /h in simplest form when f(x) = -2x -1 is equal to -2.

As given,

Given function:

f(x) = -2x -1

Express value of  in simplest form:

f( x + h ) = -2 (x + h ) - 1

             = -2x -2h -1                   ___(1)

Simplify the function by substituting value of f(x +h and f(x),

[f(x + h) - f(x) ] /h

= [ (-2x -2h -1 )- ( -2x -1 ) ] /h

Based on the dilation, the scale factor of dilation of the point is 1/3

Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.

From the question, we have the following parameters

Dilation rule: Do,k

Point = (9, 6)

Image = (3, 2)

As a general rule of dilation, the following are the properties of a scaled copy of another figure

Using the above as a guide, the scaled factor is calculated as

Scaled factor = Image/Poins

For every mile the car is driven, the cost increases by 0.52 units.

Consider a line that passes through the origin at a distance 'a' from the Y-axis and has a slope of m. In this situation, the distance an is the definition of the line's y-intercept. At this moment, the line will cross the y-axis (0, a). The equation for the line will then be y = mx + a. The same goes for a line that crosses the X-axis at a position b from the origin and has a slope of m. (b,0). The distance b is the line's x-intercept. The equation for the line will be y = m* (x-b)

Given, the equation that relates cost of renting and miles driven is
y = 0.52 x + 186
Therefore, for a car travelling one mile, cost is y₁ = 0.52*1 + 186 = 186.52
For a car travelling two miles, cost is y₂ = (0.52*2) + 186 = 187.04
Thus, for every next mile the cost increases by = y₂ - y₁ = 187.04 - 186.52 = 0.52 units

If the domain of f is ( -1, 1), then the function g defined by g(x) = f((x + 1)/(x - 1)) has a domain of; (-2, 0)

The domain of a function refers to the set of all possible intput values that make the function possible.

Now, we are given the function;

g(x) = f((x + 1)/(x - 1))

The domain would be a set of real numbers excluding 1 because at x = 1, the function is undefined.

Since the domain of  f(x)  is  -1 < x < 1  ,

Then the domain of  f(x + 1)  is  -1 < x + 1 < 1 .

domain of -1 < x + 1 < 1  will simplify to -2 < x < 0

Thus, we can say that the domain of  f(x + 1)  is  (-2, 0).

The price of one adult ticket is $5 and one student ticket is $14

Mathematical expressions can be used to depict situations or issues, and algebra is the field of mathematics that does this. For a mathematical expression to have meaning, it needs to include variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division. Algebra is used in every area of mathematics, including coordinate geometry, calculus, and trigonometry. A straightforward algebraic expression is 2x + 4 = 8.

Given that : first day of ticket sales the school sold 14 adult tickets and 5 student tickets for a total of $140. The school took in $190 on the second day by selling 10 adult tickets and 10 student tickets.

Let the price for adult ticket x and for student ticket y

we have ,

14x + 5y =140.....(i)

10x  + 10y = 190....(ii)

10 x + 10y = 190

x + y = 19

y = 19-x .....(iii)

put the value of y in equation i

14x + 5(19-x) = 140

14x + 95 - 5x = 140
