Find the equation of the line that and I [] is perpendicular to the line y = 3x - 1 passes through the point (7,4).​
Minchanka [31]

The equation of the line that goes through the point (7,4) and is perpendicular to the line y = 3x - 1 is y = -1/3 x + 7.

<h3>What is a slope?</h3>

The slope of a line is found by dividing the "vertical change" by the "horizontal change" between (any) two distinct places on the line. The ratio is sometimes stated as a quotient ("rise over run"), yielding the same value each time.

Given,

The line L₁ equation: y = 3x - 1

Line L intersects the point (x₁, y₁) = (7,4)

To determine the equation of line L.

The equation of a line whose slope and point of intersection are known is given by:

y-y₁ = m (x - x₁)

Where m is the slope of the line and (x₁, y₁) is the point it passes through.

Let L be our needed line.

We've been told that (x₁, y₁) = (7,4).

We also know that the line L is perpendicular to another line L₁, whose equation is:

y = 3x - 1

As a result, the slope of line L₁ is m₁ = 3.

= -1 3m = -1/3 m = -1/3

As a result, the equation for the required line is: y - y₁= m (x - x₁)

y-4 = -1/3(x-7)

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

3y-14 =7-x

3y = 14 + 7 - x

3y = - x + 21

y = -1/3 x + 7.

This is the required line equation.

A cylindrical pressure vessel has a height of 9 feet and a diameter of 6 feet. How much gas can the pressure vessel hold when fu
Vesnalui [34]
We are given the dimensions of a pressure vessel naming the height and the diameter. Volume of the cylinder is equal to pi d^2/4 * h. Substituting, V = pi 6^2/4 * 9 = 254.47 ft3.We convert this to m3 as an SI unit. This is equal to 7.206 m3.

Which description matches the graph of the inequality y ≥ |x + 2| – 3? a shaded region above a solid boundary line a shaded regi
Alex777 [14]
The given inequality is y ≥ |x + 2| -3.

This inequality may be written two ways:
(a) y ≥ x + 2 - 3
    or
    y ≥ x - 1

(b) y ≥ -x -2 - 3
    or
     y ≥ -x - 5

A graph of the inequality is shown below. The shaded region satisfies the inequality.

Answer: A shaded region above a solid boundary line.
