Answer:
<em>y = - </em>
<em> x + </em>
<em> </em>
Step-by-step explanation:
y = 12x - 9
Slope of line perpendicular to given is m = -
P(7, 10)
y - 10 = -
(x - 7)
<em>y = - </em>
<em> x + </em>

Answer:
Pair 1: 10 cm and 2 cm. and the sum is 12 cm.
Pair 2: 20 cm and 4 cm. and the sum is 24 cm.
Step-by-step explanation:
Area of a rectangle is given by A = LW, where L is the length and W is the width of the rectangle.
Pair 1:
For the first rectangle W = 4 cm and A = 40 sq, cm
Then
cm.
For the second rectangle W = 4 cm and A = 8 sq, cm
Then
cm.
Therefore, the sum of two unknown lengths = 10 + 2 = 12 cm. (Answer)
Pair 2:
For the first rectangle W = 4 cm and A = 80 sq, cm
Then
cm.
For the second rectangle W = 4 cm and A = 16 sq, cm
Then
cm.
Therefore, the sum of two unknown lengths = 20 + 4 = 24 cm. (Answer)

Step-by-step explanation:
probability = 
Total number of persons in the party = n
a) Pr ( every person gets their phone back) = Pr (each person picks his phone ) multiplied by number of person
=
× n = 1.
No of first m persons to pick = m
No of last m persons to pick = 1 - m
b) Pr (first m persons to pick each gets their phones back) = 
c) Pr( first m persons get a phone belonging to last m persons) = 
Answer:
Final cost = 0.9328y
Step-by-step explanation:
Assume,
Original price = y
Given:
Discount = 22%
Sales tax = 6%
Computation:
Sales tax will be added on sale value
So,
Sales price = y[100%-22%]
Sales price = 0.88y
Price after sales tax :
Final cost = 0.88y[100% + 6%]
Final cost = 0.88y[106%]
Final cost = 0.9328y
