I need help with geometry test
shtirl [24]

Answer:

1) line segment

2) square-root of 13.

3) plane F

4) Ray

5) I think the wrong image is attached, but a point would just be a dot, a line would have one dot then an arrow on the other end, an angle would be 2 lines connected with an emphasis on what's going on in between the 2 lines, a line segment is 2 dots on both ends of a line.

6)H N K I

7) (2,-8)

8) line p

9) (-2, 7)

Step-by-step explanation:

For the distance between 2 points, do (x2-x1)^2+(y2-y1)^2 then take the square root of that.

For naming a plane, as long as it is an uppercase cursive letter it is a plane.

Rays are lines without the dot on the end.

Collinear points are points that lie on the same line.

Midpoint method is finding the average between the x coordinates then the y coordinates, so think (x1+x2)/2, (y1+y2)/2, but this can be confusing with negative distances, so just think of it as on a number line, from -1 to -3 they are 4 apart, so the average between them is -2.

Y ( x + w ) = c ( x + z )
ycow [4]

The formula for x in terms of other terms in the equation is; x = (cz-yw)/(y-c).

<h3>What is the formular for x in term of other terms in the equation?</h3>

According to the task content, it follows that the variable X is to be made the subject of the formula;

Hence, it follows that;

y ( x + w ) = c ( x + z )

yx +yw = cx +cz

x(y-c) = (cz-yw)

x = (cz-yw)/(y-c)

Remarks: The complete question requires that x be made the subject of the formula.
