Solve the second equation for x. x = 2y - 8. Now sub this into the first equation to get
, and simplifying you will get 6y - 24 - 6y = -12. 6y - 6y eliminates the term, leaving us with -24 = -12, which of course is an untrue statement. This is what we refer to as an inconsistent system. These 2 lines, when solved for y give us the same slope. That is why there is no solution. A solution exists where the lines intersect. Lines with identical slopes do not intersect. What we know about the 2 lines is that they are parallel.
Answer:
0.03
Step-by-step explanation:
We have been given that a $75,000 loan requires $1,875 in discount points to be paid by seller and $375 in discount points to be paid by the buyer.
First of all, we will add the seller discount points and buyer discount points.
Now, we will divide sum of discount points by total loan amount to find the total discount points as:
Therefore, total discount points would be 0.03.
Answer:
The probability of a bulb lasting for at most 606 hours is 0.9032
Step-by-step explanation:
The mean lifetime of a bulb is 580 hours.
The standard deviation of the lifetime is 20 hours
We are supposed to find the probability of a bulb lasting for at most 606 hours i.e.
Formula :
Z=1.3
Refer the z table
Hence the probability of a bulb lasting for at most 606 hours is 0.9032
