Construct a circle through points x y and z

faust18 [17]

1. Open the compass to a little more than halfway across the line segment XY. Draw an arc centered at the first endpoint X across the line segment XY. Without changing the width of the compass, place the compass tip on the second endpoint Y. Draw a second arc across the line segment XY.
2. Line up a straightedge with the intersection of the arcs above the line XY, and the intersection of the arcs below the line. Draw a line connecting these two points. The line you draw is a perpendicular bisector. It bisects the line XY at a right angle.
3. Use a compass and straightedge to construct the bisectors of the line YZ as you did with the first line segment. Extend the bisectors long enough that they intersect. The point of their intersection is the center of the circle.
4. The radius of a circle is the distance from the center to any point on the circle’s edge. To set the width, place the tip of the compass on the center of the circle, and open the compass to any one of your original points.Swing the compass around 360 degrees so that it draws a complete circle. The circle should pass through all three points.

1. Which integer expression is equivalent to the expression below? *<br> -4 + (-9)

lana [24]

Answer:

X+Y= 12. Consecutive means in order, so in this case two odd numbers back to back. 5 and 7 are the two consecutive odd integers equal 12.

If 200% of 40% of x is equal to 40% of y, then x is what percent of y?

sp2606 [1]

Step-by-step explanation:

200÷100×40÷100× x = 40÷100 × y

2×0.4 × x = 0.4 × y

2x = y

x = y × 1÷2

x = y × 50%

Factor the trinomal below below x^2 + 5x - 24

tamaranim1 [39]

Step-by-step explanation:

When I began factoring, I used the AC method (from the form Ax^2+Bx+C).

First, I multiplied the A and C terms, so you would multiply the 1 and -24 to get -24.

Now you need to find factors that multiply to get -24 and see if the sum of any of the pairs gets B, the middle term, 5.

These factor pairs include: 1, -24; 2, -12; 3, -8; 4, -6; 6, -4; 8, -3; 12, -2; 24, -1.

The sums of the pairs are as follows: -23, -10, -5, -2, 2, 5, 10, 23.

Since the 8, -3 pair multiplies to get -24, and adds up to 5, your factors are (x+8)(x-3).

Just to be safe multiply it out to check your work.
