Answer:
Given that in a walking competition, Marlinda was 15m ahead of Sandra Evliani, and Marlinda steps 1m each time Sandra Elviani's foot steps 0.8m, to determine how many steps does Sandra Elviani have to make to match Marlinda, the following calculation must be performed:
Since Sandra Elviani walks 0.8 meters for every 1 meter that Marlinda walks, and that she has an advantage of 15 meters in the competition, it is impossible that at that rate Sandra can reach her. This is so because for each step of Marlinda, Sandra will be 0.2 meters behind her, increasing the distance (1-0.8).

Answer:
x = -47/6
y=-47
Step-by-step explanation:
<u>Slope-Intercept:</u>
y + 3 = 6(x + 2) - 3
y + 3 = 6x + 12 - 3
<u> -3 </u> <u> -3 </u>
y = 6x + 12
<u>Standard:</u>
y = 6x + 12
<u>-6x </u> <u>-6x </u>
-6x + y = 12
-1(-6x + y = 12)
6x - y = -12
<u>Graph:</u>
y = 6x + 12

↓ y-intercept

Start by graphing the y-intercept: (0, 12)
Then count the rise (up 6) and the run (right 1) from the y-intercept: (1, 18)
or
count the rise (down 6) and the run (left 1) from the y-intercept: (-1, 6)
Answer:
Step-by-step explanation:
Given
comparing it with standard equation 
so 4a=1
so Focus of parabola is (0,0)
