Solve the following equation: x2-5=7

Yuliya22 [10]

Answer:

x= 6

Step-by-step explanation:

Step 1: Write equation

2x - 5 = 7

Step 2: Solve for x

Add 5 to both sides: 2x = 12

Divide both sides by 2: x= 6

Step 3: Check

Plug in x to verify if it's a solution.

2(6) - 5 = 7

12 - 5 = 7

7 = 7

What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?

frosja888 [35]

Complete Question:

The given line segment has a midpoint at (3, 1). On a coordinate plane, a line goes through (2, 4), (3, 1), and (4, -2).

What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?

Answer:

$y = \frac{1}{3}x$

Step-by-step explanation:

From the question, we understand that the line goes through $(2, 4), (3, 1), and\ (4, -2).$

First, we calculate the slope of the above points

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where

$(x_1,y_1) = (2,4)$

$(x_2,y_2) = (3,1)$

$m = \frac{1 - 4}{3 - 2}$

$m = \frac{-3}{1}$

$m = -3$

Also; from the question, we understand that the line segment is perpendicular to the above points.

This slope (m2) of the line segment is calculated as:

$m_2 = -\frac{1}{m}$

Substitute -3 for m

$m_2 = -\frac{1}{-3}$

$m_2 = \frac{1}{3}$

Lastly, we calculate the equation of the line using:

$y - y_1 = m_2(x - x_1)$

The line segment has a midpoint at (3, 1)

So:

$y - 1 = \frac{1}{3}(x - 3)$

Open bracket

$y - 1 = \frac{1}{3}x - 1$

Add 1 to both sides

$y - 1 +1= \frac{1}{3}x - 1+1$

$y = \frac{1}{3}x$

Hence, the equation of the line segment is: $y = \frac{1}{3}x$

The product of the slopes of perpendicular lines is ?1. Which function represents a line that is perpendicular to y = ?6x + 7?

kolbaska11 [484]

Answer:

See below

Step-by-step explanation:

Perpendicular lines have slopes which are negative reciprocals. When the slopes are multiplied like 3 and -1/3 is -1.

This means the line y = -6x + 7 which has slope -6 will have a perpendicular line that has slope 1/6.

Any equation which has slope 1/6 is a solution.

Example 1/6x - 1 or 1/6x + 7 or etc.
