Multiply [tex]\frac{-9i}{-3 - 9i}[/tex] where i is the √-1
(-9i) / (-3 - 9i)
You can simplify to 9i/3+9i
Multiply by 3 - 9i / 3 - 9i
You get 27i + 81 / 90

Answer:
84
Step-by-step explanation:
y∞x
y=kx (where k is the constant)

An electrician cuts a 30 ft piece of wire into 2 pieces. One piece is 2ft longer than the other. How long are the pieces?
Answer:
piece1: 14 feet
piece2: 16 feet
Step-by-step explanation:
piece1: x
piece2: x + 2
x + x + 2 = 30
2x + 2 = 30
2x = 28
x = 14
piece1: x = 14
piece2: x + 2 = 14 + 2 = 16

According to a report, % of murders are committed with a firearm. (a) If murders are randomly selected, how many would we expect to be committed with a firearm? (b) Would it be unusual to observe murders by firearm in a random sample of murders? Why?
Full question attached
Answer:
A. 230.4
B. 3.23
Explanation:
1. if 78.26% of murders are committed with firearms, 300 murders selected at random would be expected to have been committed with 300*0.7826= 230.4 firearms
2. To find how unusual this figure is, we find standard deviation from the mean 230.4
Standard deviation = x-u/N
=254-230.4/7.311= 3.23 rounded
Therefore 254 is unusual
7.311 is calculated √np(1-p)

What is the equation of the line that passes through the point (-3,0) and has a
slope of -1/3
Step-by-step explanation:
slope= -1/3 (-3,0)
y=mx-or+b
y= -1/3(-3)+b
y= 3/3+b
y=1+b
0=1+b
b= -1
the equation is y= -1/3x-1

Step-by-step explanation:
if a box of toffies can be divided among 24 children each will get 4 how many toffies will each get if the number of children is reduced 24
Given : A box of toffies can be divided among 24 and children each will get 4 .
To Find : Number of toffies will each get if the number of children is reduced 24
Solution : If toffies are distributed among the children and each child gets 4 , then the total number of toffies will be equal to , 24 × 4 = 96 toffies .
Again it is given that the toffies are redistributed among 24 children . So the number of toffies each will get will be equal to ,
=[tex]\bf \cancel{\dfrac{96}{24}}[/tex]
=[tex]\Large\boxed{\red{\bf 4 }}[/tex]
Hence the required answer is 4 .
a roofer charges $60 for the first hour of service call and $25 per hour for each additional hour. The roofer also charges a fee for all materials used plus 30% over the cost of the materials. Let r-roofer's cost of materials and h= number of hours worked. What expression could be used to find the cost of a service call
Answer:
y=60+25h+0.3rStep-by-step explanation:
let y be the total charges
given that the hour is h
and the cost for raw material is r
therefore
1. The first hour of service call = $60
2. For each additional hour= 25h
3. 30% over the cost of the materials.= 30/100*r=0.3r
total charges
y=60+25h+0.3r
therefore the expression is
y=60+25h+0.3r

Someone answer this for brainliest.
Answer:
x < 3
Step-by-step explanation:
4x - 7 < 5
Add 7 to both sides.
4x < -2
Divide by 4 to both sides to get x alone.
x < 3
To check the answer if it's right or not, you can just plug in the 3 for x and multiply it by 4 which would equal 12 and subtract 12 - 7 which would equal 5.
Hope this helps and pls do mark me brainliest:)
Answer:
x < 3
Step-by-step explanation:
4x-7<5
4x<5+7
4x<12(divide both sides by 4)
