Answer:

to estimate the sum you round to the closest number like 38 is closest to 40 so you just say you total is $40.00

difference is when say you have 30 dollars and you spend 10 the difference is 10 dollars

The midpoint AB is M (-1,1). If the coordinates of A are (-6,-3), what are the coordinates of B

Ratling [72]

Answer:

coordinates of B is ( 4,5)

Step-by-step explanation:

If there two points (x1,y1) and (x2,y2) on a plane then coordinates of mid point is given by

m = (x1+x2)/2 , (y1+y2)/2

Given

m = (-1,1)

A= (-6, -3)

we have to point b

let point b be (x,y)

Then m (-1,1) is given by (-6+x)/2 , (-3+y)/2

(-6+x)/2 = -1

-6 + x = 2*-1 = -2

x = -2+6 = 4

also

(-3+y)/2 = 1

=> -3 + y = 2

=> y = 2 + 3 = 5

Thus , coordinates of B is ( 4,5) answer

find the ratio which are the points p(X,2) divides the line segment joining the point a(12,5) and b(4,-3) also find X plz give a

chubhunter [2.5K]

Answer: ratio a:b = 3:5 p(X, 2) = p(9, 2)

Step-by-step explanation:

Plot points a = (12, 5) and b = (4, -3) and draw a line segment from a to b.

Notice that when y = 2, X = 9 so point p = (9, 2) see graph

The distance from a to p = 3√2

The distance from b to p = 5√2

So the ratio of a:b = 3√2:5√2 = 3:5 when simplified

To find the distance, use the distance formula OR pythagorean theorem.
