If each of three lines intersects a circle at two points, what is the greatest number of separate regions that can be formed?

Mathematics

Answer:

7

Step-by-step explanation:

See the attached diagram with this answer.

If two straight lines cross a circle intersecting at two points then they can form a maximum of 4 regions within the circle, like the straight lines pq and rs form in circle c.

Now, another straight line mn is so placed that it forms the maximum number of separate regions in the circle.

Therefore, from the diagram, it is clear that there may be a maximum 7 separate regions formed by three straight lines intersecting the circle at two distinct points. (Answer)

Please help me I don’t understand this

When you're given a point and the slope of a line, it is often easiest to write its equation in point-slope form.

This is y-y_1=m(x-x_1), where (x_1,y_1) is the ordered pair for the point you are given and m is the slope.

Here, you would write y-8=-3(x-7). Then, you simplify to get to slope-intercept form, which is y = mx+b, where b is the y-intercept.

y-8=-3(x-7) \\ y=-3x+29

The correct answer is A.

Answer:

Decimal = -1.375, Fraction = -11/8

Step-by-step explanation:

Decimal:

-2.25 + 0.4x = -2.8

0.4x = -0.55

x = -1.375

Fraction:

-9/4 + 2/5x = -14/5

-45/20 + 8/20x = -56/20

8/20x = -11/20

x = -11/8

Hopefully this helps!
