The graph below shows the velocity f(t) of a runner during a certain time interval: graph of line segment going through ordered

pairs 0, 6 and 6, 8. Graph of another line segment going through the ordered pairs 6, 8 and 8, 0. Label on the x axis is time in seconds and label on the y axis is velocity in meters per second Which of the following describes the intercepts on the graph? The initial acceleration of the runner was 8 m/s2, and the runner stopped after 6 seconds. The initial acceleration of the runner was 6 m/s2, and the runner stopped after 8 seconds. The initial velocity of the runner was 8 m/s, and the runner stopped after 6 seconds. The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds.

Which of the following equations is in equation formed when completing the square on y^2 - 12 y= -27
bogdanovich [222]

Answer:

(y-6)^2=9

Step-by-step explanation:

Given

y^2 - 12y = -27

Required

Get equivalent expression using completing the square

<em>Follow these steps:</em>

  • <em>Take the coefficient of y; That is -12</em>
  • <em>Divide it by 2; That is (-12/2)</em>
  • <em>Square it: (-12/2)^2</em>

<em />

Add to both sides of the equation

y^2 - 12y + (\frac{-12}{2})^2= -27 + (\frac{-12}{2})^2

y^2 - 12y + (-6)^2= -27 + (-6)^2

y^2 - 12y + 36= -27 + 36

y^2 - 12y + 36= 9

Expand the right-hand side

y^2 - 6y - 6y + 36= 9

Factorize:

y(y-6)-6(y-6) =9

(y-6)(y-6)=9

(y-6)^2=9

PLEASE ANSWER ASAP TODAY WILL GIVE BRAINLIEST TO FIRST RIGHT ANSWER.
Lisa [10]

Answer:

y-7=3(x-9)

Step-by-step explanation:

It appears they want your answer in point-slope form, which is identified by the equation y-y1=m(x-x1)

Step 1: Find the slope (m)

m=(y2-y1)/(x2-x1)

m=(-8-7)/(4-9)

m=(-15)/(-5)

m=3

The slope is m=3

Step 2: Plug in m, y1, and x1

y-y1=m(x-x1)

y-7=3(x-9)

Therefore our final equation is y-7=3(x-9)

(4, -3), (x, 1); slope -4
Alexandra [31]

Answer:

x = 3

Step-by-step explanation:

m =  \frac{y \frac{}{2}  - y \frac{}{1} }{x \frac{}{2}  - x \frac{}{1} }

m = slope

x, y = coordinates

- 4 =  \frac{1 - ( - 3)}{x - 4} \\  - 4(x - 4)   = 1 + 3 \\  - 4x  + 16 = 4 \\  - 4 x = 4 - 16 \\  - 4x =  - 12 \\  x=  \frac{ - 12}{ - 4}  \\ x = 3
