MAXImum [283]

The appropriate phrase from the list that uses the verb/subject agreement is "When someone in my family<u> has a birthday</u>, we always <u>have a party"</u>.

<h3>What is verb/subject agreement?</h3>

The Subject-verb agreement simply means that a subject and its verb must be both singular or plural. In this case, a singular subject takes a singular verb and a plural subject takes a plural verb.

From the complete question, the appropriate phrase from the list that uses the verb/subject agreement is "When someone in my family<u> has a birthday</u>, we always <u>have a party"</u>.

For how many integers $n$ does the inequality $x^2 + nx + 15 &lt; 0$ have no real solutions $x$?.
Rom4ik [11]

By making the determinant equal to or smaller than zero, we will see that there are 15 values of n such that the inequality has no real solution.

<h3>Solving the inequality:</h3>

Here we have the inequality:

x^2 + n*x + 15 < 0

We want to see for which values of n we don't have real solutions.

Now, we can write the quadratic equation:

y = x^2 + nx + 15.

If the determinant of this quadratic equation is negative or 0, then we have a single root or we don't have roots, and because the leading coefficient is positive, that would mean that the function never becomes negative. Then for these cases, the inequality has no real solutions.

Then we must have:

n^2 - 4*15*1  ≤ 0

Now we can solve this for n.

n^2 ≤ 60

Then if n^2  is smaller than 60, we don't have real solutions, and we know that:

√60 = 7.75

Then we have:

-7.75 ≤ n ≤ 7.75

But n can only be an integer, so we can write:

-7  ≤ n ≤ 7

From -7 to 7 there are 15 integers, then there are 15 values of n such that the inequality has no real solutions.
