Answer:
Option A. y= -1/5x + 5
Step-by-step explanation:
step 1
Find the slope of the given line
we have
y=5x-2
The slope m is
m=5
step 2
Find the slope of a line perpendicular to the given line
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is -1)
m1*m2=-1
we have
m1=5
(5)*m2=-1
m2=-1/5
therefore
The equation of a line perpendicular to the given line could be
y= -1/5x + 5
Answer:
t = $4400 +/- $450
mean = $4400
standard deviation = $450
Step-by-step explanation:
Given;
Base salary b = $2000
Sales s = $8000 +/- $1500
Commission c = 30% sales = 0.3 × s
Total Salary t = base salary + commission = b + c
Commission c = 0.3×s = 0.3×($8000 +/-$1500)
c = $2400 +/- $450
Total salary t = b + c
Substituting the values;
t = $2000 + ($2400 +/- $450)
t = $4400 +/- $450
mean = $4400
standard deviation = $450
Answer:
2/5
Step-by-step explanation:
first, we convert the mixed fractions to improper fractions,
so then we find what
=
and that equals , which equals . We can simplify that to 2/5
Hey there! :)
Answer:
p(x) = 6x - 15
Step-by-step explanation:
If p(x) = r(x) - c(x), subtract the two equations. Therefore:
p(x) = 10x - (4x + 15)
p(x) = 10x - 4x - 15
Combine like terms and simplify:
p(x) = 6x - 15
