Y = -1/2X +4

Step-by-step explanation:

x1 y1 x2 y2

2 3 0 4

(Y2-Y1) (4)-(3)= 1 ΔY 1

(X2-X1) (0)-(2)= -2 ΔX -2

slope= - 1/2

B= 4

Given segment AB with points (-4, 8) and (6, 3) respectively. Find the coordinates of point P that partitions Segment AB in the

netineya [11]

Answer:

$P = (2,5)$

Step-by-step explanation:

Given

$A(-4,8)$

$B(6,3)$

$m:n = 3 : 2$

Required

Determine P

Since P divides the segment into 3:2, P is calculated using

$P = (\frac{nx_1 +m x_2}{m+n},\frac{ny_1 + my_2}{m+n})$

Where

$(x_1,y_1) = (-4,8)$

$(x_2,y_2) = (6,3)$

$m:n = 3 : 2$

Substitute these values in the above formula:

$P = (\frac{2 * -4 +3 * 6}{3 + 2},\frac{2 * 8 + 3 * 3}{3 + 2})$

$P = (\frac{-8 +18}{3 + 2},\frac{16 + 9}{3 + 2})$

$P = (\frac{10}{5},\frac{25}{5})$

$P = (2,5)$

A uniform border on a framed photograph has the same area as the photograph. What are the outside dimensions of the border if th

Black_prince [1.1K]

Given dimension of photograph = 25cm * 20cm

So area of photograph = 500cm²

Now, let the width of frame border be = x

So, dimensions of photograph + frame= (25 + 2x)*(20 + 2x)

As given, the area of frame is same as photograph , so

Area of picture + frame = 1000cm ²

Hence, area equals

$4x^{2}+90x+500=1000$

$4x^{2}+90x-500=0$

$2x^{2}+45x-250=0$

Solving this quadratic equation,

For the quadratic equation of the form $ax^{2}+bx+c=0$ , solution is:

x1,2 = $\frac{-b+\sqrt{b^{2}-4ac}}{2a}$

Now putting a=2, b=45, c= -250 and solving he above equation, we get two values of x.

x = -27.11 (discard it as it is negative) and

x = 4.61 cm

Hence the dimensions of the frame are:

20+2x = 20+2(4.61) = 29.22 cm

25+2x = 25+2(4.61) = 34.22 cm
