Answer:

The Y value part of the point's coordinates will always stay the same, and then calculate the distance from the point's x value to the line -2 and then count the same amount in the opposite direction. For example, if the point was (-3,1), then the point is 1 left from the line, so you will go point one right from the line and get the answer (-1,1)

A, B, and C are collinear, and B is between A and C. The ratio of AB to BC is 3 : 1.

S_A_V [24]

Coordinates of point C: (1,-1)

Step-by-step explanation:

In this problem, A, B and C are collinear, and B is between A and C.

The ratio AB : BC is 3 : 1.

This means that we can write the following two equations:

$x_B-x_A = 3(x_C-x_B)\\y_B-y_A=3(y_X-y_B)$

where:

$(x_A,y_A)=(-7,3)$ are the coordinates of point A

$(x_B,y_B)=(-1,0)$ are the coordinates of point B

$(x_C,y_C)$ are the coordinates of point C

Solving the equation for $x_C$ ,

$x_C = x_B + \frac{x_B-x_A}{3}=-1+\frac{-1-(-7)}{3}=1$

Solving the equation for $y_C$ ,

$y_C=y_B + \frac{y_B-y_A}{3}=0+\frac{0-3}{3}=-1$

So, the coordinates of point C are

$C(-1,1)$

scoundrel [369]

Answer:

Adult is $12 and child is $7

Step-by-step explanation:

Adult=x and Children=y

first day: 4x+1y=55

second: 3x+2y=50

Get one letter the same but opposite

(4x+1y=55) times that by -2

-8x+-2y=110

3x+2y=50

minus all of that u get

-5x=60

divide 60 by 5

x=12

fill in X

3(12)+2y=50

36+2y=50

-36 -36

2y=14

/2 /2

y=7
