slope = -2

y >= -2x - 5

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

Mama L [17]

For this case we have that by definition, the equation of the line in a slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have the following equation:

$y = 2x + 2$

Thus, the slope is $m_ {1} = 2$

By definition, if two lines are perpendicular then the product of the slopes is -1.

$m_ {1} * m_ {2} = - 1$

We find $m_ {2}:$

$m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {2}$

Thus, the equation of the line is:

$y = - \frac {1} {2} x + b$

We substitute the given point to find "b":

$3 = - \frac {1} {2} 6 + b\\3 = -3 + b\\b = 6$

Thus, the equation of a line perpendicular to the given line and passing through the given point is:

$y = - \frac {1} {2} x + 6$

Answer:

$y = - \frac {1} {2} x + 6$

Two mechanics worked on a car. The first mechanic worked for 20 hours, and the second mechanic worked for 5 hours. Together they

FinnZ [79.3K]

Answer:

The rate per hour of the 1st mechanic is US$ 115, and the rate of the 2nd mechanic is US$ 120.

Step-by-step explanation:

1. Let's review all the information given to answer the question correctly.

Time of the 1st mechanic working on the car = 20 hours

Time of the 2nd mechanic working on the car = 5 hours

Total rate of the work done by the two mechanics = US$ 2,900

2. What was the rate charged per hour by each mechanic if the sum of the two rates was 235 per hour?

Rate per hour of the 1st mechanic = x

Rate per hour of the 1st mechanic = 235 - x

For solving the value of x, we will use the following equation:

x * 20 + 5 * (235 - x) = 2,900

20x + 1,175 - 5x = 2,900

15x = 2,900 - 1,175 (Like terms)

15x = 1,725

x = 115 (Dividing by 15 at both sides)

The rate per hour of the 1st mechanic is US$ 115, therefore the rate of the 2nd mechanic is US$ 120 (235 - 115).

Total charged by the 2 mechanics = 115 * 20 + 120 * 5

Total charged by the 2 mechanics = 2,300 + 600

Total charged by the 2 mechanics = 2,900
