Write the equation of the line that has an undefined slope and passes through the point (4, 7).

Answers

Answer 1

The equation of the line that has an undefined slope and passes through the point (4, 7) is y = 4.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know if a line has an undefined slope it is parallel to the y-axis and passes through the point (4, 7).

As it is parallel to the y-axis x-coordinate point remains the same.

So, The equation of the line must be, y = 4.

what is linear equations ?

A linear equation is one that satisfies the algebraic formula y=mx+b. The foregoing sentence is sometimes referred to as a "linear equation with two variables" because y and x are variables. Bivariate linear equations are two-variable linear equations. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. An equation is said to be linear if its formula is y=mx+b, where m denotes the slope and b the y-intercept. It is referred to as being linear when an equation has the form y=mx+b, where m stands for the slope and b for the y-intercept.

The solution to the equation x² + 3x - 5 = 0 are ( -3 - √( 29 ))/2 and ( -3 +√( 29 ))/2.

What are the solutions to the given equation?

The quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

To solve for x, we use the quadratic formula

x = (-b±√(b² - 4ac)) / (2a)

Given the equation in the question;

x² + 3x - 5 = 0

Hence;

a = 1

b = 3

c = -5

We substitute this values into the quadratic formula above.

x = (-b±√(b² - 4ac)) / (2a)

x = ( -3 ± √( 3² - ( 4 × 1 × -5) )) / ( 2 × 1)

x = ( -3 ± √( 9 - ( -20 ) )) / ( 2 )

x = ( -3 ± √( 9 + 20 )) / 2

x = ( -3 ± √( 29 )) / 2

x = ( -3 - √( 29 ))/2, x = ( -3 +√( 29 ))/2

Therefore, the two values of x are  ( -3 - √( 29 ))/2 and ( -3 +√( 29 ))/2.

Answers

Since triangle A'B'C' is an image of triangle ABC after a rotation and the center of rotation is D, the length of side B'C' is equal to 4 units.

What is a rotation?

In Mathematics, a rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

Generally speaking, rotation simply refers to a type of transformation that preserves both the shape and side lengths of a geometric figure.

In this context, we can reasonably infer and logically deduce that the magnitude of side length BC before a rotation of the triangle would be equal to side length BC B'C' after rotation:

Side BC = side B'C'

4 = 4

In conclusion, the length of side B'C' is equal to 4 units.

What is the derivative of 7e to the 7x?

Answers

The derivative of 7e to the 7x is 7e to the 7x * 7ln(e) * 7. The derivative of 7e to the 7x can be found by first taking the natural logarithm of the base, in this case e7x.

1. Take the natural logarithm of the base: ln(e7x)

2. Take the derivative of the natural logarithm: 7x*ln(e)

3. Apply the chain rule: 7e7x * 7ln(e) * 7

The derivative of 7e to the 7x can be found by first taking the natural logarithm of the base, in this case e7x. The natural logarithm of e7x is ln(e7x). Taking the derivative of the natural logarithm yields 7x*ln(e). We then apply the chain rule to get the final result of 7e7x * 7ln(e) * 7. In other words, the derivative of 7e to the 7x is equal to 7 multiplied by e raised to the 7x power, multiplied by 7ln(e), and then multiplied by 7 once more. This can be simplified to 7e7x * 7ln(e)7.

What is the slope of the line (- 3 4 and 0 2?

Answers

The slope of the line (-3, 4) and (0, 2) is -2/3.

In the given question, we have to find the slope of the line (-3, 4) and (0, 2).

A line's slope is defined as the ratio of the change in the y coordinate to the change in the x coordinate.

The given points are (-3, 4) and (0, 2).

We can find the slope from the given point using the formula

m = [tex]\frac{y(2)-y(1)}{x(2)-x(1)}[/tex]

From the given points;

x(1) = -3, y(1) = 4, x(2) = 0, y(2) = 2

Now putting the values in the formula;

m = (2 - 4)/(0 - (-3))

m = (-2)/(0 + 3)

m = -2/3

How to translate coordinates?

To translate coordinates in a two-dimensional plane, you need to know the translation vector. A translation vector is a pair of numbers (a, b) that indicates the amount of movement in the x-direction and y-direction.

To translate a point (x, y) by the translation vector (a, b), you can use the following formulas:

x' = x + a

y' = y + b

Where x' and y' are the new coordinates of the point after the translation.

A translation is a transformation that moves a figure a certain distance in a certain direction without rotating or reflecting it. In this case, we are asked to translate the triangle EFG 2 units down. This means that we need to move the triangle down 2 units on the y-axis.

To translate a point (x, y) down 2 units, we can add -2 to the y-coordinate. The new coordinates of the point will be (x, y - 2).

The coordinates of E are (-4, 1), so the coordinates of E' after the translation are (-4, 1-2) = (-4,-1)

The coordinates of F are (-3,-2), so the coordinates of F' after the translation are (-3,-2-2) = (-3,-4)

The coordinates of G are (2, 1), so the coordinates of G' after the translation are (2,1-2) = (2,-1)

So the new coordinates for the triangle EFG' after the translation are:

E'(-4,-1)

F'(-3,-4)

G'(2,-1)

It's important to notice that the x-coordinates didn't change because we are only translating the triangle down, on the y-axis.

Rectangle is a flat, four-sided shape with four right angles and a pair of parallel lines. It is one of the most basic and commonly used shapes in geometry.

They are also used in a variety of other applications, such as designing window frames, creating art, and laying out floor plans.

To determine the area of DFCE, multiply the length of the base (DF) by the height (CE). The area of the two yellow rectangles, KH'C'J and LJE'A', can be determined by adding the area of each rectangle. The area of rectangle KH'C'J is equal to the product of the length of its base (KH') and the height (C'J).

Answer:

The first step in solving this system of equations by elimination method is to eliminate one of the variables by adding or subtracting the two equations.

-9x - 4y = 1

3x + 3y = 3

If we multiply the first equation by 3 and the second equation by -9, we get:

-27x - 12y = 3

-27x - 27y = -27

Now we can add these two equations:

-12y = -24

y = 2

Now we can substitute this value of y back into one of the original equations to find the value of x.

-9x - 4(2) = 1

-9x - 8 = 1

-9x = 9

x = -1

So the solution of this system of equations is (x,y) = (-1,2)

Answer:

You just have to plug in one equation into the other, though you might already know this but the answer would be,
