5. If a point is equidistant from the endpoints of a segment, then it must be the midpoint of the segment. True
6. The set of all points in the plane that are a given distance from a
line segment is a pair of lines parallel to the given segment. True
Distribute: 4x - 2 - 100 = 0
add 102 to both sides: 4x = 102
Divide both sides by 4: x = 25.5
I'll solve for y
xy+(4(20))>x-5y(2+9-7)
xy+4(20)>x-5y(2+9-7)
xy+4(20)>x-5y(4)
xy+4(20)>x-20y
xy+80>x-20y
xy+20y+80>x
y(x+20)>-80+x
y>(-80+x)/(x+20)
Answer:
It should be A. -12^2
Step-by-step explanation:
Looking at the box B, you have to multiple 3x and -4x. 3 * -4 is -12 and the two x's become squared. Making your answer -12x^2
Start with the sum of x and 9, giving the expression
![x + 9](https://tex.z-dn.net/?f=x%20%2B%209)
This is divided by 2 so
![\frac{x + 9}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%20%2B%209%7D%7B2%7D%20)
This equals 3x so the equation is
![\frac{x + 9}{2} = 3x](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%20%2B%209%7D%7B2%7D%20%20%3D%203x)
This can the be solved.
Multiply both sides by 2 to get
![x + 9 = 6x](https://tex.z-dn.net/?f=x%20%2B%209%20%3D%206x)
Then take x from both sides
![9 = 5x](https://tex.z-dn.net/?f=9%20%3D%205x)
Divide by 5 to get the value for x
