y equals the quantity negative 3 times x plus 7 end quantity over 4.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given a linear equation in two variables.

3x+ 4y = 7

We have to find an expression to calculate y from the equation.

Subtracting both sides of the equation with 3x, we get,

3x + 4y - 3x = 7 - 3x

4y = 7 - 3x

Dividing throughout by 4,

4y/4 = (7 - 3x)/4

y = (7 - 3x) / 4

Hence the value of y is the quantity negative 3 times x plus 7 end quantity over 4.

The ratio of a circle can be found through the formula A = πr2, where A is the area of the circle and r is the radius of the circle.

To find the ratio of a circle, you must first calculate the area of the circle. To calculate the area, multiply the value of π (3.14159) by the square of the radius (r2). For example, if the radius of the circle is 4, the area of the circle would be 3.14159 x 42, which is equal to 50.2653. The ratio of a given circle can then be found by dividing the area of the circle (50.2653) by the square of the radius (42), which gives 1.273.

Answer:

The first number is 4, the second is 3

Step-by-step explanation:

We can make 2 equations, let x be the first number, and y be the second number.

x = 3y - 5

4x - 2y = 10

We sub x = 3y - 5

=> 4(3y - 5) - 2y = 10

=> 12y - 20 - 2y = 10

=> 10y - 20 = 10

=> 10y = 30

=> y = 3

Sub y = 3 into x = 3y - 5

x = 3(3) - 5

x = 4

Therefore, the first number is 4, and the second is 3

The value of h in terms of x when the volume of cylinder is equal to that of cone is h = 6x²

Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface. The unit of volume is in cubic units such as m3, cm3, in3 etc. Sometimes, volume is also termed capacity.

The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together.

The volume of cylinder = πr²h

and volume of cone = 1/3 πr²h

since the volume of the cone and cylinder are equal

πr²h = 1/3 πr²h

r in cylinder = x cm and h is 2x

r in cone = x cm

therefore πx²×2x = 1/3πxh

divide both side by πx

π2x³/πx = h/3

2x² = h/3

therefore h = 3×2x²

h = 6x²

Every point in the plane that is a certain distance away from a certain point forms a circle (center). It is, thus, a curve formed by points moving in the plane at a fixed distance from a point. At every angle, it is also rotationally symmetric about the center. A circle is a closed two-dimensional object where every pair of points in the plane are equally spaced out from the "center." A line that goes through the circle creates a specular symmetry line. At every angle, it is also rotationally symmetric about the center.

We know, Central angle (θ) = (length arc)/radius ….(1)

Convert angle in radian:

Angle in radians = Angle in degrees x π/180° = 197° x π/180 = 1.09

Mark the sides BC and DF as congruent.

A triangle in geometry is a three-sided polygon with three edges and three vertices.

The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic.

This characteristic is known as the triangle's angle sum property.

If ABC is a triangle, it is written as ABC, where A, B, and C represent the triangle's vertices.

In Euclidean geometry, a triangle is a two-dimensional shape that is represented by three non-collinear points in a single plane.

A closed, two-dimensional shape is a triangle. It is a polygon with three sides. Straight lines make up all of the sides.

The vertex is the intersection of two straight lines. The triangle therefore has three vertices.

Step-by-step explanation:

σ total ^ 2 = σ randi ^2 + σ leah ^2 = 1.1^2 + 1.8^2 = 4.45

σ total = √4.45 = 2.1

Randi and Leah can expect the total number of hours spent studying to vary by approximately 2.1 hours from the mean.

The correct option is C.

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.

Given:

Randi and Leah are studying together for an exam.

Let X represent the number of hours Randi spends studying nightly, and let y represent the number of hours Leah spends studying nightly.

The mean of X is 4.5 hours with a standard deviation of 1.1 hours, and the mean of Y is 3.7 hours with a standard deviation of 1.8 hours.

Assuming these are independent random variables,

S = X + Y

σ²  = σ²(Randi)² + σ²(Leah)

    = (1.1)² + (1.8)²

σ  = 2.1

Since the equation is now equal to 0, this means that r is equal to 0. We can confirm this by substituting 0 in for r in both equations:

For the given quadratic equation, the solutions are x = -3 and x = -3.

What is the completing square method?

The completing the square method is a technique used to solve quadratic equations of the form y = ax² + bx + c. The goal of this method is to convert the equation into the standard form of a quadratic equation, which is y = a(x + h)² + k, where a, h and k are constants.

To solve y = x² + 6x + 8 by completing the square, we need to add and subtract a value to the equation so that the x-term (x² + 6x) is a perfect square. In this case, we need to add and subtract (6/2)² = 9 to the equation, which gives us:

y = x² + 6x + 8

y = (x² + 6x + 9) - 1

Now, we can take the square root of the x-term, which is (x + 3)², and we get:

y = (x + 3)² - 1

The equation is now in the standard form of a quadratic equation, with y = (x + 3)² - 1. We can now solve for x by taking the square root of both sides of the equation and getting x = -3, -3 .

Alternatively, We can also solve for x by factoring the expression inside the square, which would give (x + 3) (x + 3) = 0 and x = -3, -3
