Answer:

9 sides.

Step-by-step explanation:

1260 = 180(n - 2) Divide both sides by 180:

7 = n - 2

n = 7 + 2 = 9.

Answer:

9 sides

Step-by-step explanation:

Given the sum of the interior angles = 1260°, then

180° (n - 2) = 1260 ( divide both sides by 180 )

n - 2 = 7 ( add 2 to both sides ), hence

n = 9

What are the solutions to the equation x2 = 289?

artcher [175]

Because this is a second degree equation you will have 2 solutions. When you take the square root of a number you have to account for both the positive and negative roots. Since the square root of 289 is 17 then your solutions are +17 and -17.

The graph of a proportional relationship passes through (12,16) and (1,y). find y

anastassius [24]

Answer:

4/3

Step-by-step explanation:

A proportional relationship is a relationship that crosses through the origin or (0,0). This means the slope of the line can be found by subtracting the points (12,16) and (0,0) in the slope formula.

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{16-0}{12-0}= \frac{16}{12}=\frac{4}{3}$

So the slope is 4/3 and must be the value between any two points on the line.

This means the function moves from (0,0) to (1, 4/3).
