Answer:
A
Step-by-step explanation:
Answer:
All you have to do is combine the like terms. Once you do that you get: -4x+3y=-11
Answer: 80
-----------------------------------------
Explanation:
x = number of defective drives in the shipment of 20,000 total
We are told that 2 defective drives are in the shipment of 500. So the first fraction to set up is 2/500
The second fraction is x/20000 as we divide in the same order as before (number of defective over the total)
Set those two fractions together to get this proportion
2/500 = x/20000
Now cross multiply
2/500 = x/20000
2*20000 = 500*x
40000 = 500*x
500x = 40000
The last step is to divide both sides by 500 to isolate x
500x = 40000
500x/500 = 40000/500
x = 80 which is the answer we want
Note: This is an expected/estimated amount and not entirely guaranteed to be reality. It's based on the previous ratio of 2/500, assuming the same ratio is held in check.
Answer:
I think that it may be the last one
Step-by-step explanation:
Answer:
y= 2x+1
Step-by-step explanation:
Points:
Form of the line:
- y=mx+b, m- the slope, b- y-intercept
Finding the slope:
- m= (y2-y1)/(x2-x1)
- m=(3-1)/(1-0)= 2/1= 2
Line is now:
Using one of the given points to find out the value of b:
So the equation for the line is:
