The equation y = -5x - 1 is steeper than the equation y = -2x - 7.

In mathematics, the relative slope or rate of change of two lines or curves is referred to as "steeper." If one line or curve's slope or rate of change is larger than another, it is said to be steeper than the other.

To compare the steepness of two linear equations, we can look at their slopes, which represent the rate of change of the dependent variable (y) with respect to the independent variable (x). The slope of a line is given by the coefficient of x in the equation y = mx + b, where m is the slope.

Let's compare the slopes of the two equations:

y = -5x - 1: The coefficient of x is -5, so the slope is -5.

y = -2x - 7: The coefficient of x is -2, so the slope is -2.

Since the slope of the first equation (-5) is greater in magnitude than the slope of the second equation (-2), we can conclude that the first equation is steeper than the second equation.

Alternatively, we can look at the absolute values of the slopes. The absolute value of the slope of the first equation is 5, which is greater than the absolute value of the slope of the second equation, which is 2. This confirms that the first equation is steeper than the second equation.

Therefore, the equation y = -5x - 1 is steeper than the equation y = -2x - 7.

[tex](x - 3)^2 + (y + 2)^2 = 41[/tex]

Step-by-step explanation:

The general shape of the equation is:

(x-a)² + (y-b)² = r²

Where (a,b) is the center and r is the radius.

(a,b) = (3,-2) is given.

To find the radius r, or even simpler, r², calculate the distance between (-3,2) and (8,2) using pythagoras.

r² = (8-3)² + (2--2)² = 41

Pythagorean theorem tells us how the side lengths of right triangles are related.

The Pythagorean theorem, also known as the Pythagorean identity, states that the sum of the squares of the lengths of the two sides forming the right angle is equal to the square of the length of the hypotenuse in any right triangle (the side opposite the right angle). In other words, the Pythagorean theorem can be used to calculate the length of the hypotenuse given the lengths of the two sides of a right triangle.

This relationship can be written as the equation:

[tex]a^2 + b^2 = c^2[/tex]

where a and b are the lengths of the legs, and c is the length of the hypotenuse. The Pythagorean Theorem is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery.

Define Proportion.

The word "proportion" generally denotes a portion, share, or sum when contrasted to a total. When two ratios are equal, they are in proportion, as stated by the definition of proportion. Two ratios or fractions are equal when an equation is applied, or when a statement to that effect is made.

Two sets of supplied numbers are said to grow or fall in the same ratio in terms of proportion if they are directly proportionate to one another. For proportionality, use the symbols ":" or "=".

The area of the path is 256 square feet.

What is the area of rectangle?

The area of a rectangle is given by the formula:

Area = length x width

where "length" and "width" are the dimensions of the rectangle. To find the area of a rectangle, simply multiply the length by the width.

To find the area of the path surrounding the rectangular garden, we need to subtract the area of the garden from the area of the larger rectangle that includes the path. The larger rectangle measures 25 feet by 43 feet.

Area of the larger rectangle = 25 ft * 43 ft = 1075 sq ft

Area of the garden = 21 ft * 39 ft = 819 sq ft

So, the area of the path surrounding the garden is:

Area of the larger rectangle - Area of the garden = 1075 sq ft - 819 sq ft = 256 sq ft

a) Now, the mean number of cars owned for this sample is,

⇒ Mean = (79 + 79 + 59 + 94) / 4

a) The coordinates of G are (3, -4)

b) The name of the line through G and E is y = (-3/2)x + 13/2

(a) Since the line x=1 is a line of symmetry for triangle EFG, we know that G must lie on the same line of symmetry, and hence its x-coordinate should be reflected across the line x=1 from the x-coordinate of E.

The x-coordinate of E is 5, so the x-coordinate of G should be 5-2=3. That is, G has an x-coordinate of 3.

Similarly, since the line x=1 is a line of symmetry, the y-coordinate of G should be the same as the y-coordinate of F, which is -4. Therefore, G has a y-coordinate of -4.

Thus, the coordinates of G are (3, -4).

(b) To find the name of the line through G and E, we can first calculate the slope of the line:

slope = (y2 - y1)/(x2 - x1) = (-4 - 2)/(3 - 5) = -3/2

The line through G and E has a slope of -3/2.

Next, we can use the point-slope form of the equation of a line to find the equation of the line. We can use either point E or point G to write the equation, but it might be easier to use point G since we have already calculated its coordinates.

Using point-slope form with point G and the slope -3/2, we get:

y - (-4) = (-3/2)(x - 3)

Simplifying and rearranging, we get:

y = (-3/2)x + 13/2

The transformations applied are: reflection about the x-axis, horizontal shift 10 units to the right, and vertical shift 400 units up.

A parabola is a symmetrical, U-shaped curve that can be formed by intersecting a plane with a cone. It is defined by the quadratic equation [tex]y = ax^2 + bx + c.[/tex]

Solution:

To identify the transformations that have been applied to the graph of [tex]f(x) = x^2[/tex]to produce the graph of [tex]g(x) = -5x^2 + 100x - 450[/tex] we can start by looking at the standard form equation for a parabola:

[tex]y = a(x - h)^2 + k[/tex]

where (h, k) is the vertex of the parabola and "a" determines the shape and direction of the parabola.

For[tex]f(x) = x^2[/tex], we have a = 1, h = 0, and k = 0, so the vertex is at (0, 0).

For [tex]g(x) = -5x^2 + 100x - 450[/tex], we can rewrite it as:

[tex]g(x) = -5(x^2 - 20x + 90)[/tex]

Completing the square inside the parentheses, we get:

[tex]g(x) = -5(x - 10)^2 + 400[/tex]

So the vertex of the parabola is (10, 400), and the "a" value is -5, which means the parabola is upside-down compared to[tex]f(x) = x^2.[/tex]

Therefore, the transformations that have been applied to f(x) to obtain g(x) are:

1. The graph is reflected vertically (flipped upside-down) due to the negative "a" value.

2. The graph is shifted 10 units to the right and 400 units up, which corresponds to a horizontal translation of 10 units and a vertical translation of 400 units.

In summary, the transformations applied are: reflection about the x-axis, horizontal shift 10 units to the right, and vertical shift 400 units up.

One of the most fundamental curvilinear geometric shapes, a cylinder has historically been a three-dimensional solid. It is regarded as a prism with a circle as its base in basic geometry. An infinite curvilinear surface is another way to describe a cylinder. A cylinder's surface area is the area that its surface takes up in three dimensions. A three-dimensional structure known as a cylinder has circular bases that are parallel to one another. There are no vertices on it. The area of three-dimensional shapes often refers to the surface area. Square units are used to denote the surface area.

The numerator of the z-score test statistic measures the difference between the sample mean and the population mean (or the hypothesized population mean, depending on the context) in terms of the standard error of the mean.

It can use z- test only if the population standard deviation is known (or given) and the sample is large (more than 30 units)

If the mean and standard deviation is known, then the z-score is calculated using the formula.

z = (x - μ) / σ

Car B leaves the Grand Canyon at 2 pm and travels at 90 mph without stopping.To calculate when Car B will catch up with Car A, we need to find the time difference between their departure times and the difference in their speeds.Car A leaves one hour before Car B, so we can subtract 1 hour from the total travel time. The difference in their speeds is 10 mph, which is equivalent to 1/8 of an hour for every hour of travel. Therefore, we can subtract 1/8 of an hour from the total travel time for every hour of travel.We can use these two deductions to calculate the total travel time: 3 hours - 1 hour - 3/8 of an hour = 2 5/8 hours.
