Find the coordinates of the midpoint of line segment lb if l (8, 5) and b (-6, 2).

jeyben [28]

Answer:

The coordinates of the midpoint of the segment is (1,3.5)

Step-by-step explanation:

In this question, we are concerned with finding the coordinates of the mid point of the line that joins segment lb

To do this, we shall be using the midpoint formula;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

Where (x1,y1) = (8,5)

(x2,y2) = (-6,2)

Thus;

(x, y) = (8 + (-6))/2, (5 + 2)/2

(x ,y) = (2/2), (7/2)

(x,y) = (1,3.5)

PLS PLS HELP, I DONT WANT TO FAIL!!

Flura [38]

Answer:

2.0 seconds

Step-by-step explanation:

Given quadratic functions:

$\begin{cases}y=-7x^2+26x+3\\y=-6x^2 +23x+5\end{cases}$

To find the time, in seconds, that the balloons collided at the highest point, substitute one equation into the other equation and rearrange to equal zero:

$\begin{aligned}-6x^2+23x+5 & = -7x^2+26x+3\\-6x^2+23x+5+7x^2 & = -7x^2+26x+3+7x^2\\x^2+23x+5 & = 26x+3\\x^2+23x+5-26x & = 26x+3-26x\\x^2-3x+5& = 3\\x^2-3x+5-3& = 3-3\\x^2-3x+2& = 0\end{aligned}$
