Answer:
<em>n</em> - <em>k</em> + 1
Step-by-step explanation:
This is assuming (because you did not say) that <em>n</em> and <em>k</em> are integers and <em>n</em> is greater than <em>k</em>.
Example: from 2 to 5 {2, 3, 4, 5} includes 5 - 2 + 1 = 4 numbers.
Example: from -6 to 4 includes 4 - (-6) + 1 = 11 numbers, namely {-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4}
Y=1x-10 (sorry I could be wrong)
Answer:
x= 3
y = 0
Step-by-step explanation:
•Add the two equations to cancel out +6x and -6x
•Find the value of y
•Substitute the value of y into equation 1 to find the value of x.
Hope I was able to help you:)
