Find the slope of the line that passes through (-2, 8) and (-10, 14)
vesna_86 [32]
Hello!

To find the slope we divide the difference of the y-values by the difference of the x-values as shown below.

\frac{14-8}{-10+2} = -\frac{6}{8} = -\frac{3}{4}

The slope of our line is -3/4.

I hope this helps!

For a large data set of a average student grades, the third quartile Q3 is found 78.5 . What does the mean when we say that 78.5
xz_007 [3.2K]

Step-by-step explanation:              

We are told that for a large data set of a average student grades, the third quartile Q3 is found 78.5.

Since we know that third quartile represents the number such that 75% of the data is less than this number. Third quartile is the middle value between median and the highest value of a data set. Third quartile is also known as upper quartile. Third quartile splits lower 75% data from highest 25% of data.

Therefore, third quartile represents that 75% of student grades are less than 78.5 and 25% of students grades are greater than 78.5.

evelyn has $638.54 in her checking account. she must maintain a $500 balance to avoid a fee. she wrote a check for $159.50 today
Pachacha [2.7K]

The inequality is:

x + $488.04 ≥ $500

And the solution is

x ≥ $11.96

<h3>How to write and solve the inequality?</h3>

First, let's define x as the amount that she needs to deposit.

Now, we know that at the moment Evely has $638.54 in her bank account. Then she pays for $638.54, then she writes a check for $159.50, then we need to subtract that:

$638.54 - $159.50 = $488.04

Now she needs to deposit an amount x, such that her balance is at least $500, then we can write the inequality:

x + $488.04 ≥ $500

Solving that for x, we get:

x ≥ $500 - $488.04 = $11.96

She needs to deposit at least $11.96.
