Simplify.<br> 3^2+ (9-8/2)
solmaris [256]

Hi there! Hopefully this helps!

-----------------------------------------------------------------------------------------------------------

Answer: 14.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First we calculate <u>3 to the power of 2</u> and get 9.

|

\/

9 + 9 - \frac{8}{2} = 14.

Now we add<u> 9 + 9</u> to get 18.

18 - \frac{8}{2} = 14.

Then, we<u> divide 8 by 2</u> to get 4.

18 - 4 = 14.

Then we subtract<u> 4 from 18</u> to get.....You guessed it,<u> 14</u>!

HELP PLEASE!! WILL GIVE BRAINLIEST!!!

Answer:

Slope = 2 Y-Intercept = (0, 3)

Step-by-step explanation:

Slope : \frac{Rise}{Run}  which is \frac{y2 - y1}{x2 - x1} from two points: point1 (x1 , y1) and point2 (x2, y2).

For the purpose of getting the slope I will be using point (0, 3) as point 1

and point (-3, -3) as point 2.

If you plug in 0 as x1, 3 as y2, -3 for x2, and -3 for y2:

\frac{-3 - 3}{-3 - 0} = \frac{-6}{-3} = 2

Y-Intercept: The y intercept is the point where the line is touching the y axis. Which in this graph, there is only point (0,3).
