The expression x-2 has a value of -5 for some value of x. For the same value of x, what is the value of the expression (x-2)² +

ankoles [38]

X - 2 = -5
x = -5 + 2
x = -3

(x-2)^2 + 5x - 10...when x = -3
(-3-2)^2 + 5(-3) - 10
-5^2 - 15 - 10
25 - 15 - 10
10 - 10

Which of the following is true about the bisectors of a segment in a plane?

oksian1 [2.3K]

The bisector of a segment is a line, a ray, or a segment that intersects the segment at its midpoint. In a plane, there is an infinite number of lines that passes through every point, so, in a plane, there is an infinite number of bisectors of a segment.

Answer: D. every segment has infinitely many bisectors

Casey orders 3 pizzas and 2 orders of breadsticks for a total of $29.50. Rachel orders 2 pizzas and 3 orders of breadsticks for

saveliy_v [14]

The cost of one pizza is $8.5

Step-by-step explanation:

Let,

Cost of one pizza = x

Cost of one bread stick = y

According to given statement;

3x+2y=29.50 Eqn 1

2x+3y=23 Eqn 2

Multiplying Eqn 1 by 2

$2(3x+2y=29.50)\\6x+4y=59\ \ \ Eqn\ 3$

Multiplying Eqn 2 by 3

$3(2x+3y=23)\\6x+9y=69\ \ \ Eqn\ 4$

Subtracting Eqn 3 from Eqn 4

$(6x+9y)-(6x+4y)=69-59\\6x+9y-6x-4y=10\\5y=10$

Dividing both sides by 5

$\frac{5y}{5}=\frac{10}{5}\\y=2$

Putting y=2 in Eqn 1

$3x+2(2)=29.50\\3x+4=29.50\\3x=29.50-4\\3x=25.5$

Dividing both sides by 3

$\frac{3x}{3}=\frac{25.5}{3}\\x=8.5$

The cost of one pizza is $8.5

Construct a perpendicular bisector to AB.

monitta

Answer:

Take a fixed gap and draw 180 degree arc of equal size on each side.

The compass size should be the same for the whole process, be careful.

Make 90 degrees angle for both side and cross two arcs from each 90 degrees. The point thus obtained should be produced vertically towards the line AB. The point on the line segment is the line bisector.
