Graph the function. Identify the focus.
1. y = -x²
3. y = 11
5. y = x

Locate the y-intercept on the graph and plot the point.  

From this point, use the slope to find a second point and plot it.  

Draw the line that connects the two points.

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
