Step-by-step explanation:
So in the equation given, y = 2x - 3
you substitute x for whats given in the table in the x column.
Example 
In the graph the first number under the x colum is -1.
y = 2x - 3 in the equation you take out x and put -1. 
So now the equation becomes y = 2 × -1 - 3.
Using bedmas to solve the question you should get -5
Which now means y = -5
To plot the point now x would be -1 and y would be -5 (-1, -5)
Same thing for the second number in the x Column. 
y = 2 × 1 - 3 which equals -1
To plot it 
x = 1 y = -1. (1, -1)
And for the last number 3. 
Agai. You substitute x for 3 which makes the equation y = 2 × 3 - 3 
this gives you 3 and to plot it 
x would be 3 and y would be 3 
 
        
             
        
        
        
Answer:
   6 2/3 minutes
Step-by-step explanation:
Their rates in "jobs per hour" are ...
   (60 min/h)/(15 min/job) = 4 jobs/h
and
   (60 min/h)/(12 min/job) = 5 jobs/h
So, their combined rate is ...
   (4 jobs/h) + (5 jobs/h) = 9 jobs/h
The time required (in minutes) is ...
   (60 min/h)/(9 jobs/h) = (60/9) min = 6 2/3 min
Working together, it will take them 6 2/3 minutes.
 
        
             
        
        
        
When the insurance company want a plan with a deductible of $4,000, they need to charge a minimum of $18000 for premiums.
<h3>What is a deductible?</h3>
It should be noted that a deductible simply means the amount of money that is paid out of the pocket of the policy holder.
From the information given, each accident costs $18,000 on average. Therefore, this is the minimum amount of premium.
When they want a plan with a premium of $1,000, the amount that they'll need to charge for deductibles will be:
= (4000/18000) × 1000
= $220

This is the commutative property of addition. It basically says, x+y=y+x.
