Step-by-step explanation:

You will need the distance formula.

\(d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\)

Now you can plug in your 2 points.

A(\(x_{1}\), \(y_{1}\))

B(\(x_{2}\), \(y_{2}\))

\(d = \sqrt{(-1 - (-4))^2 + (4-8)^2}\)= 5

Given that, Margaret drove to an appointment at 50 miles per hour. Her speed on her return was 40 miles per hour. The trip back took one quarter of an hour longer.

The question is asking to determine the distance Margaret drove to her appointment in miles. The formula used to solve the problem is as follows;

distance = speed × time Given that the distance to and from the appointment are the same. Distance to the appointment (going) = Distance from the appointment (returning)Distance = Distance Going = Distance Returning Let's determine the time it took Margaret to drive to her appointment using the formula above. Distance = speed × time Distance Going = 50 mph × t (where t represents time)Distance Going = 50tThe time it took her to drive back is (t + 0.25) since the return took one quarter of an hour longer. Distance = speed × timeDistance Returning = 40 mph × (t + 0.25)Distance Returning = 40t + 10Using the formula Distance = Distance Going = Distance Returning50t = 40t + 10Subtract 40t from both sides.50t - 40t = 10t = 10Thus, t = 1The distance going to the appointment is;Distance Going = 50tDistance Going = 50 × 1Distance Going = 50 , Margaret drove 50 miles to her appointment.Answer: Margaret drove 50 miles to her appointment.

Answer:

6/9+6/9

find the LCM, which is 9

9÷9=1, 1×6=6

since it is the same thing

6+6/9 = 12/9

= 1 whole number 3/9 or 1 whole number 1/2

The equation square root of (x + 3) + 6 = 9 has two potential solutions, x = 0 and x = 6. However, upon analysis, it is determined that x = 0 is an extraneous solution while x = 6 is not extraneous.

To find the result of the given equation, we'll break it step by step and also determine if any results are extraneous.

 The given equation is

 √( x + 3) 6 = 9

 Let's break it

Step 1 Subtract 6 from both sides of the equation

√( x +3) = 9- 6

√( x +3) = 3

 Step 2 Square both sides of the equation to exclude the square root

( x + 3) = \(3^{2}\)

( x + 3) = 9

 Step 3 Subtract 3 from both sides of the equation

x = 9- 3

x = 6

 The result to the equation is x = 6.

Now, let's determine if this result is extraneous or not.

 To check if the result is extraneous, we need to substitute it back into the original equation and see if it holds true.

Original equation √( x + 3) + 6 = 9

 Substituting x = 6

√( 6 +3) + 6 = 9

√ 9 +6 = 9

3 +6 = 9

9 = 9

Since the equation holds true when x = 6, the result x = 6 is NOT an extraneous result.

thus, the correct statements are

 x = 0; not extraneous

x = 6; not extraneous

The n-ary rule for linear sequences is 7n - 1. The given sequence is an arithmetic sequence.

What is Arithmetic Progression?

Any two consecutive integers in a sequence are in "arithmetic progression" (AP) if their difference is constant.

The formula is given by Tn = a + (n - 1) d. where,

a, first term = 6 n, number of terms

d, binomial tolerance = 13 - 6 = 7

So substitute the value into the equations. It will be as follows.

Tn = a + (n - 1)d

= 6 + (n - 1)7

= 6 + 7n - 7

= 7n - 1

So the n term of this sequence is 7n - 1.

To construct the incenter of a triangle, construct the angle bisectors of each angle of the triangle. Here are the steps to construct the incenter of a triangle:

Draw the three sides of the triangle using a straightedge.

Choose one of the angles of the triangle and draw its bisector. To do this, place the point of your compass on the vertex of the angle, and draw an arc that intersects both sides of the angle. Without changing the width of your compass, place it on each of the two points where the arc intersects the sides of the angle, and draw two more arcs that intersect. The point where these two arcs intersect is the point where the angle bisector meets the opposite side of the triangle.

Repeat step 2 for the other two angles of the triangle. You should now have three lines that intersect at a single point.

The point where all three angle bisectors intersect is the incenter of the triangle.

Note that the incenter of a triangle is the center of the circle that can be inscribed inside the triangle.

2. z = 1 - 2·i    →    √5

3. z = 4 + 3·i   →      54

4. z = 6 - 8·i    →     10

1. z = √5 - i      →    √6

Step-by-step explanation:

1. z = √5 - i

The distance from the origin = √((√5)² +1²) = √(5 + (-1)²) = √6

Therefore, z = √5 - i → √6

2) z = 1 - 2·i

The distance from the origin = √(1² + (-2)²) = √5

Therefore, z = 1 - 2·i → √5

3) z = 4 + 3·i

The distance from the origin = √(4²+3²)) = √(16 + 9) = √25 = 5

Therefore, z = 4 + 3·i → 5

4) z = 6 - 8·i

The distance from the origin = √(6²+8²)) = √(36 + 64) = √100= 10

Therefore,  z = 6 - 8·i →  10

To determine the set of points of the plane (x, y) for which x × y is > or the same as 0, and |x|<1, we need to consider the following cases: Case 1: x > 0 and y > 0 . In this case, x × y is positive. Since |x|<1, we have -1 < x < 1. Therefore, the set of points for this case is {(x, y) | 0 < x < 1, y > 0}.

Case 2: x < 0 and y < 0
In this case, x × y is positive. Since |x|<1, we have -1 < x < 0. Therefore, the set of points for this case is {(x, y) | -1 < x < 0,  y < 0}.
Case 3: x > 0 and y < 0
In this case, x × y is negative. Since |x|<1, we have -1 < x < 1. Therefore, the set of points for this case is {(x, y) | 0 < x < 1,   y < 0}.
Case 4: x < 0 and y > 0
In this case, x × y is negative. Since |x|<1, we have -1 < x < 0. Therefore, the set of points for this case is {(x, y) | -1 < x < 0, y > 0}.
Therefore, the set of points of the plane (x, y) for which x × y is > or the same as 0, and |x|<1 is given by the union of the above sets, which is: {(x, y) | -1 < x < 1, y > 0} ∪ {(x, y) | -1 < x < 0, y < 0} ∪ {(x, y) | 0 < x < 1, y < 0} ∪ {(x, y) | -1 < x < 0, y > 0}. The set of points (x, y) in the plane for which x * y ≥ 0 and |x| < 1 are the points where either both x and y are positive or both are negative, and the absolute value of x is less than 1. This corresponds to the regions in the first and third quadrants where the x-coordinate is between -1 and 1.

There are 46 lattice points on the line segment between $(3,17)$ and $(48,281)$.

A lattice point is a point in the plane with integer coordinates. To find the number of lattice points on a line segment, we can use the formula for counting lattice points on a straight line.

The formula states that the number of lattice points on a line segment between two points \($(x_1, y_1)$\) and \($(x_2, y_2)$\) can be calculated using the greatest common divisor (GCD) of the differences in the x-coordinates and y-coordinates of the two points.

In this case, the two endpoints of the line segment are (3,17) and (48,281). We can calculate the differences in the x-coordinates and y-coordinates as follows:

Δx = 48 - 3 = 45

Δy = 281 - 17 = 264

To find the GCD of Δx and Δy, we can simplify each difference by dividing them by their common factors. In this case, both 45 and 264 are divisible by 3, so we divide them by 3 to get:

Δx = 45 ÷ 3 = 15

Δy = 264 ÷ 3 = 88

The GCD of Δx and Δy is 1, which means there are no common lattice points other than the endpoints. Therefore, the number of lattice points on the line segment between $(3,17)$ and $(48,281)$ is equal to the number of endpoints, which is 2.

In conclusion, there are 46 lattice points on the line segment, including both endpoints.
