The x intercept of f(x) is same as x intercept of g(x) and the statements the y intercept of f(x) is same as y intercept of g(x) are true.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The function  f (x) = x² -7x

when we translate the graph f(x) to g(x) it can be seen that g(x) is a translation of f(x) by left and upwards.

So the statements the x intercept of f(x) is same as x intercept of g(x) and the statements the y intercept of f(x) is same as y intercept of g(x)

Hence, the x intercept of f(x) is same as x intercept of g(x) and the statements the y intercept of f(x) is same as y intercept of g(x) are true.

The width of the flag is 640 ft and the length is 1040 ft

To calculate this we can take the width of the flag can be represented as "w" and the length as "l".

From the information given, we know:

l = w + 400 (because the length is 400 ft greater than the width)

2 * (w + l) = 2080 (because the perimeter is 2,080 ft)

We can substitute the first equation into the second equation to get:

2 * (w + w + 400) = 2080

2w + 800 = 2080

2w = 1280

w = 640

Therefore, the width of the flag is 640 ft and the length is 1040 ft (since l = w + 400)

To simplify a polynomial, we have to do two things:

1) combine like terms, and

2) rearrange the terms so that they're written in descending order of exponent.

In order to combine like terms, we must first determine which terms can be added to or subtracted from one another. The same variable (with the same exponent) is always associated with like expressions. For instance, adding one "x-squared" to two "x-squareds" results in three "x-squareds," but adding one "x-squared" to a "x" is impossible because the two words are unrelated.

An algebraic expression that displays the sum of monomials is called a polynomial. Since "mono" signifies "one" in the prefix, a monomial is a singular element or phrase. 'Poly' is a prefix that means'many. Thus, an expression that has numerous terms is said to be polynomial. The relationships between the terms may be sums or differences.

The equation 2x + 3y = 16 has infinitely many solutions.

We know that a linear equation in two variables is of the form ax + by + c = 0, where a, b, c are non-zero real numbers.

Here we have been given a linear equation in two variables 2x + 3y = 16

We solve this equation for x,

Consider 2x + 3y = 16

2x + 3y - 3y = 16 - 3y            .........(subtract 3y from each side of equation)

2x/2 = (16 - 3y)/2                   .........(divide each side by 2)

x = (16 - 3y)/2

for any real value of y we can find value of x.

This means, an equation 2x + 3y = 16 has infintely many solutions.

For x = 0,

2(0) + 3y = 16

y = 16/3

y = 5.333

This means, the y-intercept of line 2x + 3y = 16 is (0, 5.333)

For y = 0 ,

2x + 3(0) = 16

x = 16/2

x = 8

The two numbers are  x = 13/2 and y = 11/2.

Let's call the two numbers x and y. We are given that:

x + y = 12 (the sum of the two numbers is 12)

x - y = 1 (the difference between the two numbers is 1)

We can use these two equations to solve for x and y.

From the first equation, we can add y to both sides to get:

x = 12 - y

Now we can substitute this into the second equation:

(12 - y) - y = 1

12 - 2y = 1

12 = 1 + 2y

2y = 11

y = 11/2

Now that we know the value of y, we can substitute it back into x = 12 - y to find the value of x:

x = 12 - (11/2)

x = 12 - 11/2

x = (24 - 11)/2

x = 13/2

So the two numbers are x = 13/2 and y = 11/2.

The graph of an inverse proportion is a curved graph.

When two variables are related in a way where their product is always constant, that relationship is called an inverse proportion. Y = k/x or xy = k, where k is a constant, are two ways to express it mathematically. Hyperbolas which are curved graphs are formed with inverse proportions. Collecting all points in the plane where the gap between two fixed points and a fixed point is constant is known as a hyperbola.

With the foci on the y-axis and the x-axis serving as the hyperbola's centre, the graph of the equation y = k/x is a hyperbola. The y-axis serves as the hyperbola's centre of gravity, with the x-axis serving as its foci, on the graph of the equation xy = k.

The inequality that can be used to determine x, the maximum number of outfits Luis can purchase while staying within his budget is x ≤ 4

How is inequity resolved?

Luis has $420 to spend at a bicycle shop on new accessories and clothing.

He spends $209.67 on a brand-new bicycle.

He spends $6.04 apiece on two bicycle reflectors and $25.77 on a pair of cycling gloves.

He intends to use all or part of the remaining funds to purchase new riding clothing at $37.16 apiece.

Therefore,

x is the maximum amount of clothes Luis can buy on a tight budget.

In order to illustrate the scenario, the inequality that may be employed is as follows:

209.67 + 6.04(2) + 25.77 + 37.16x ≤ 420

235.44 + 12.08 + 37.16x ≤ 420

247.52 +  37.16x ≤ 420

37.16x ≤ 420 - 247.52

37.16x ≤ 172.48

divide both sides by 37.16

x ≤ 4.64155005382

A rotation of 270° counterclockwise will map the blade formed by ΔFEG onto the blade formed by ΔHGI

The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

270° clockwise rotation: (x,y) becomes (-y,x)

270° counterclockwise rotation: (x,y) becomes (y,-x)

Given data ,

Let the first triangle be represented as ΔFEG

Let the second triangle be represented as ΔHGI

Now , for both the triangles to be similar , the mapping of the rotation of the blade should be rotated once in the clockwise or three times in the counterclockwise direction

So , for a rotation of 90° clockwise rotation: (x,y) becomes (y,-x)

So , for a rotation of 270° counterclockwise rotation: (x,y) becomes (y,-x)

The ΔFEG of the blade will map itself onto the ΔHGI of the blade after a rotation of 270° counterclockwise rotation

Answer:

Domain is  [-1, 3]

Range is [1, 2]

================================

Explanation:

The domain is the set of allowed input values. It's the set of all possible x coordinates of the points shown.

The left-most point is when x = -1, while the right-most point is at x = 3.

We can say [tex]-1 \le \text{x} \le 3[/tex] meaning x is between -1 and 3, including both endpoints.

That compound inequality translates to the interval notation [-1, 3]

Square brackets are used to include the endpoints.

-----------------

The range handles the set of possible y outputs.

The lowest we can go on the graph is y = 1, and the highest is y = 2

Therefore we arrive at [tex]1 \le \text{y} \le 2[/tex] which translates to [1, 2]
