Ine segment ab has endpoints a(–4, –10) and b(–11, –7). to find the x-coordinate of the point that divides the directed line segment in a 3: 4 ratio, the formula x = (x2 – x1) + x1 was used to find that x = (–11 – (–4)) + (–4). therefore, the x-coordinate of the point that divides ab into a 3: 4 ratio is

-7

Step-by-step explanation:

The coordinates of the point wich divide the segment AB, where in ratio can be calculated using formula

In your case,

Hence,

Therefore, x-coordinate of the point that divides AB into a 3:4 ratio is -7.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

happy to
