Look at the table. Make a conjecture about the sum of the first 15 positive even numbers.

Olenka [21]

Be observing the table, we can write the following conjecture:

When adding consecutive even numbers, starting from 2 to $m$ .

Then the sum is equal to:
$\frac{m}{2}( \frac{m}{2} +1)$

Then, the sum of the first 15 positive even numbers (which is the sum of 2 to 30) can be calculated with the previous conjecture by setting $m=30$ :
$\frac{m}{2}( \frac{m}{2} +1)=\frac{30}{2}( \frac{30}{2} +1)=(15)(16)=240$

The answer is 240.

Can I get some help we just started this today

Alja [10]

Answer:

-2

Step-by-step explanation:

The slope of a line tells us how y responds to a change in x. If the slope is 2, it means that for every time x increases by 1, will will go up by 2.

We can calculate slope from a line, or with two given points. I used points (0,4) and (3,-2). Slope is the "Rise/Run."

The Rise: (-2 - 4) = -6

The Run: (3 - 0) = 3

Slope = Rise/Run = (-6/3) = -2
