Answer:
y = -0.2x - 5.8
Step-by-step explanation:
If a line is given in the form y = mx + b, the "m" is the slope.
For the line given y = 5x, the slope is 5
The line that is perpendicular to this will have slope that is "negative reciprocal of that".
So, the perpendicular line will have slope of
So, the Perpendicular Line will have equation:
y = -1/5x + b
Let's find b by replacing x with 6 and y with -7 [the point given]. So we have:
So the equation of perpendicular line = y = -0.2x - 5.8
Answer:
11 years old
Step-by-step explanation:
If four brothers have the average age 6, then the sum of their ages is
years.
Let x years be the age of sister. If four brothers and their sister have the average age 7, then
Multiply this equation by 5:
The sister is 11 years old.
<h3>The minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000</h3>
<em><u>Solution:</u></em>
<em><u>The expression to Michael earnings is:</u></em>
Where,
b is the base salary, which is $ 900 in this sum
c is the commission rate
Given that commission rate is 5%
s is the sales
Michael must have to earn at least $2500 in a month
Here, at least means, "greater than or equal to" 2500
The inequality is framed as:
base salary + 5 % on sales 2500
Solve the inequality
Thus, minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000
