A pound of apples and a pound of oranges each cost $2.50.

Pound is a unit of weight or mass commonly used in the imperial system of measurement. It is equal to 0.453 kilograms and 16 ounces. It is also known as the avoirdupois pound, which is the most commonly used today. In some contexts, the term "pound" may also refer to a unit of currency, the British Pound Sterling (GBP).

This can be determined by subtracting Gina's total cost from Tom's total cost.
Tom's cost was $8.00, and Gina's cost was $5.00, so 8.00 - 5.00 = 3.00. Since Tom bought 3 pounds of apples more than Gina and the same amount of oranges, the cost of the extra apples is $3.00.
Since each pound of apples and oranges costs the same amount,
then $3.00 divided by 3 pounds is $1.00,
so each pound of apples and oranges costs $2.50.

slope intercept form is y = mx+c

m is 1 and c is 4

y=- x +

Step-by-step explanation:

A straight line with a positive and constant slope can be represented by the system of equation 2x + 3y = 5 and 4x + 6y = 7.

The line is a linear equation, which is a line of constant slope. The slope of the line is determined by the coefficients of the variables in the equation.

It can be calculated by dividing the coefficient of the x-term by the coefficient of the y-term. In this example, the slope of the line is calculated by dividing 2/3, which is equal to 0.67.

This indicates that the line has a positive slope. The line is a line of best fit, meaning that it will pass through all the points defined by the two equations. The line will also pass through the point of intersection of the two equations, which is the point (2,1).

The same line of equations can be written in two different ways in a dependent equation. The lines that appear when we graph dependent equations are the same.

The solutions to these kinds of equations are infinite rather than fixed.

When the same line is written in two different ways, a dependent system of equations has infinite possible solutions. When attempting to solve for a system of equations, these two scenarios arise. When working through a system of equations, you'll need to keep track of a few words from your vocabulary.

A system of equations is formed by the two equations y=2x+5 and y=4x+3. The system's solution is the ordered pair that results from resolving both equations. One solution, an infinite number of solutions, or nothing at all can be found for a system of two linear equations.

Rotation and dilation in geometry

For the rotation of 180° counterclockwise about the origin, we will use the rotation formula:

(x, y) → (xcosθ - ysinθ, xsinθ + ycosθ)

Where θ is the angle of rotation.

For our 180° rotation, θ = 180°.

We calculate the new coordinates for each vertex:

X(-6, 4) → X'(-6, -4):

(-6cos180° - 4sin180°, -6sin180° + 4cos180°)

Y(0, 6) → Y'(0, -6):

Z(-4, 2) → Z'(-4, -2):

(-4cos180° - 2sin180°, -4sin180° + 2cos180°)

For the dilation of the triangle with a scale factor of 3/2 centered at the origin, we will use the dilation formula:

(x, y) → (kx, ky)

Where k is the scale factor.

For our dilation, k = 3/2.

To find the intermediate step in the form of (x+a)=b for the equation x^2+5x+11=13x, we need to first move all the terms to one side of the equation.

x^2+5x+11 = 13x

x^2 - 8x + 11 = 0

To solve this equation, we can factor it.

x^2 - 8x + 11 = 0

(x-11)(x-1) = 0

So, we have two solutions for x: x = 11 and x = 1

To find the intermediate step in the form of (x+a)=b, we can write each solution as (x+a)=b

x = 11, so (x+(-11)) = 11

x = 1, so (x+(-1)) = 1

So, the intermediate step in the form of (x+a)=b for the equation x^2+5x+11=13x is:

(x-11) = 11 and (x-1) = 1

Answer:

function-function relation

Step-by-step explanation:

To determine if the inverse of a function is a function, we can use the horizontal line test.

A function is a set of ordered pairs (x, y) where each x value corresponds to one and only one y value. The inverse of a function is a set of ordered pairs (y, x) where each y value corresponds to one and only one x value.

To use the horizontal line test, we draw a horizontal line on a graph of the original function. If the line intersects the graph in more than one point in any vertical section, the inverse is not a function. But if the horizontal line intersects the graph in at most one point in any vertical section, the inverse is a function.

Another way to check if the inverse of a function is a function is to check that the original function is a one-to-one function, meaning that each x value corresponds to one and only one y value. If the original function is not one-to-one, then the inverse is not a function.

It's also possible to check if the inverse of a function is a function by analyzing the equation of the function. If the original function is a one-to-one function, its inverse is also a function

A degree is a unit of measurement for expressing the measurement of an angle. Angles are typically measured in two different units: radians and degrees. Angles are always measured in degrees in practical geometry.

A degree is denoted by the symbol °. (degree symbol). A complete angle in degrees is 360 degrees (sometimes written as 360°), which equals one complete rotation.

73.14 % of the 6.45-ounce bottle of mixed fruit juice is not juice.

To find out how much of the 6.45-ounce bottle is not juice, we need to subtract the amount of juice in the bottle, which is 1.751 ounces, from the total volume of the bottle, which is 6.45 ounces.

6.45 ounces - 1.751 ounces = 4.699 ounces

So, 4.699 ounces of the 6.45-ounce bottle is not juice.

Alternatively, we can express the answer as a percentage of the total volume of the bottle:

(4.699 / 6.45) x 100 = 73.14 %

So, 73.14 % of the 6.45-ounce bottle of mixed fruit juice is not juice.

Step-by-step explanation:

The standard form equation of a circle with center (a, b) and radius r is

[tex](x-a)^2 + (y-b)^2 = r^2[/tex]

where (a, b) is the center of the circle.

Here we are given that the circle has center (9, 2)

So the equation becomes

[tex](x-9)^2 + (y-2)^2 = r^2\cdots(1)[/tex]

All we have to do is find the radius and we are done

Circumference of a circle with radius r
[tex]= 2 \pi r\\[/tex]

Given circumference [tex]= 10\pi[/tex]

[tex]10\pi = 2\pi r\\\implies r = 10/2 = 5[/tex]

Substitute this into equation (1):
[tex](x-9)^2 + (y-2)^2 = 5^2\\\\(x-9)^2 + (y-2)^2 = 25\\[/tex]

This corresponds to option B.

The equation of a circle is (x - 9) + (y - 2) = 25.

Option B is the correct answer.

A circle is a two-dimensional figure with a radius and circumference of 2πr.

We have,

The equation of a circle is (x - h) + (y - k) = r² _____(A)

Where (h, k) is the center and r is the radius.

Now,

Centre = (9, 2)

This means,

(h, k) = (9, 2) _____(1)

Circumference = 10π

This means,

2πr = 10π

2r = 10

r = 5 in ____(2)

Now,

Substituting (1) and (2) in (A).

(x - h) + (y - k) = r²

(x - 9) + (y - 2) = 5²

(x - 9) + (y - 2) = 25

Thus,

The equation of a circle is (x - 9) + (y - 2) = 25.
