Answer:
Step-by-step explanation:
when the line goes down like that you know the slope's going to be negative. so now you do rise/run. down two over 1, down two over 1. so your slope is -2

Hello from MrBillDoesMath!
Answer: Choice "B", which is 3
Discussion:
The consecutive integers <= 7 are
1,2,3,4,5,6,7
4 is the largest number in this list that makes sense in this problem (for example, 5 + 6 > 7, 7 + 6 > 7 don't satisfy the problem)
1 + 2 = 3 <= 7
2 + 3 = 5 <= 7
3 +4 = 7 <=7 (*)
The lesser integer in the last equation (*) is 3
Thank you,
MrB
a)
Add the score and then square the sum.
By using the summation notation we can write the above statement is (Σx)²
b)
Square each score and then add the squared values.
By using the summation notation we can write the above statement is Σx²
Subtract 2 point from each score and then add the resulting values.
By using the summation notation we can write the above statement is Σ(x-2)
Subtract 1 point from each score and square the resulting values. Then add the squared values.
By using the summation notation we can write the above statement is Σ(x-1)²
Answer:
The equivalent fraction is:
which agrees with the second answer in the list of options
Step-by-step explanation:
Recall that in order to rationalize a denominator of this type (remove the square roots), we need to multiply numerator and denominator of the fraction we have by the conjugate of the binomial. That is, multiply top and bottom of the fraction by the expression:
Therefore we have:
Then this is the equivalent rationalized expression:
