62.5 is your answer in decimal
Step-by-step explanation:
-4x + 3 < 23
-4x < 20
x > -5
hmm,I don't think we need to put equal sign instead of (<) , for when we started calculating.
we can just keep the question as it is and calculate.
Answer: The slope is 5
Step-by-step explanation:
You can calculate the slope of the line with this fomula:

Given the points (2,3) and (1,-2), you can identify that:

Now, the final step is to substitute these values into the formula
, getting that the slope of this line is:


The two systems have the same solution.
The correct answer is 3) since the first equation of system B is indeed the addition of the first equation of system A and 4 times the second equation of system A.
Answer: 3)
