Answer: "Use the straightedge to draw a line through points X and Y." is the right answer.


Step-by-step explanation:

To perpendicular bisector of line segment AB. There are following steps:

1) Draw arcs from points A and B on the both sides of AB.

2) Name the intersection points as X and Y.

3) Use the straightedge to draw a line through points X and Y.

4) Name the point as O

hence we have construct perpendicular bisector XY of AB which bisects at O.

Daniel [21]

Answer:

43 mph

Step-by-step explanation:

1 day = 24 hours

3 days = 3 × 24 hours = 72 hours

The car taveled 3106 miles in 72 hours.

average speed = distance/time

Example 5
Svetllana [295]

Answer:

1/2*6(12+x)=12*x

1/2*(72+6)=12x

36+3x=12x

36=9x

4=x

Step-by-step explanation:

Check that x=4

1/2*6(4+12)=12*4

1/2*(24+72)=48

1/2(96)=48

48=48

So x=4 is the correct answer

So, I undestood slope right. But, I get confused with the other points that intersect there is multiple of them. How do i look f
ivanzaharov [21]

Answer:

slope = 2

Step-by-step explanation:

Find 2 points on the line that land perfectly on the grid. I'll choose these 2 here:

(-2, -1) and (0, 3)

Rise is the change in the y value from one point to the other, and run is the change in the x. Looking at these 2 points, y went from -1 to 3. That is a <em>rise</em> of 4. The x went from -2 to 0, so that is a <em>run</em> of 2. "rise over run" means rise literally over run in a fraction like this:

m=\frac{rise}{run}

The more proper way to calculate slope looks like this, but it's really the same thing in the end:

m=\frac{y2-y1}{x2-x1}

where (x1, y1) and (x2, y2) are your 2 points.

Finally, the slope of this line is:

m=\frac{3--1}{0--2}\\\\m=\frac{4}{2}\\\\m=2

That's a rise of 4 over a run of 2, and that simplifies to just a slope of 2.
