2 Point M is the midpoint of line segment BC. If the coordinates of Mare (-1,1) and the coordinates of B are (3,4), find the coordinates of Point C
a(-5,-2)
b(7,7)
c(2,5)
b(1,5/2)

a(-5,-2)

Step-by-step explanation:

The midpoint of a segment

Given points C(xc,yc) and B(xb,yb), the coordinates of the midpoint M can be found knowing that:

Applying that relation in both axes separately, we can write:

Knowing the coordinates of the midpoint and B, we can find the coordinates of the other extreme C solving both equations for the required variable:

Plugging in the known values: M=(-1,1) and B=(3,4):

The coordinates of C are (-5,-2)

a(-5,-2)

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
