The correct answer is A. y - 3 = -6(x + 1) of the  linear equation in point-slope form for the line that goes through (-1,3) and (1, -9).

To write the linear equation in point-slope form, we need to use the formula:

[tex]y - y_1 = m(x - x_1),[/tex]

where [tex](x_1, y_1)[/tex] represents one of the given points, and m represents the slope of the line.

Step 1: Find the slope (m):

[tex]m = \frac {(y_2 - y_1) }{(x_2 - x_1)}\\= \frac {(-9 - 3)} { (1 - (-1))}\=\frac {-12 } {2}= -6.[/tex]

Step 2: Choose one of the given points (-1, 3), and substitute its coordinates into the point-slope form:

[tex]y - 3 = -6(x - (-1)).[/tex]

Step 3: Simplify and rearrange the equation:

[tex]y - 3 = -6(x + 1)\\y - 3 = -6x - 6.[/tex]

Therefore, the correct equation is A. y - 3 = -6(x + 1).

Answer:

Mean: 123

Median: 28

Mode: 23

Step-by-step explanation:

give brainliest

Answer:

Mean = 123, Median = 28 , Mode = 23

Step-by-step explanation:

Mean is the average of all the numbers.

Mean = [tex]\frac{3+721+23+63+27+29+95+23}{8} \\= \frac{984}{8} \\= 123[/tex]

Median is the middle most value of the numbers when arranged in ascending order. (Average of the 2 middlemost numbers if there are even number of values.)

Arranged Values: 3,23,23,27,29,63,95,721

Median = [tex]\frac{27+29}{2} \\= \frac{56}{2} \\= 28[/tex]

Mode is the value that occurs the most in the numbers.

Mode =  23

We will see that Jo's speed, rounded to 2 digit places, is:

S =  6.42 km/h

Remember that:

speed = distance/time.

Nina takes 2 hours and 10 minutes to finish the race, first, let's write the time in hours:

1 hour = 60 min.

Then:

10 min = (10/60) hours = 0.167 hours.

So we can write the time as:

2.167 hours.

And the distance is 13km, so her speed is:

S = 13km/2.167h = 6 km/h

The time that she takes to reach a distance of 11km (where she meets with Jo) is:

T = 11km/(6 km/h) = 1.83 hours.

Now, Jo starts 7 minutes after Nina, then the time in which he travels the 11 km is:

1.83 hours - 7 minutes.

Where:

7 min = (7min/60 min) hours = 0.117h

Then the time is:

T= 1.83h - 0.117h = 1.713 hours.

So he travels 11km in 1.713 hours, then his speed is:

S = 11km/ 1.713 hours = 6.42 km/h

Answer:

3/4

Step-by-step explanation:

Scale factor is the ratio between two different triangles. They can be scaled if they are similar triangles, which they are (in this case). Since we know that these two triangles are similar, we want to match all the sides up in a way where they all have the same ratio.
NK=3 and AH = 4, so NK/AH = 3/4.
GK=6 and LH = 8, so GK/LH = 6/8 = 3/4.
GN = 15 and LA = 20, so GN/LA = 15/20 = 3/4.
We found the matching ratios, so the answer is 3/4.

Answer:

84.8

Step-by-step explanation:

Begin by finding the total area of the circle. You have been given the radius.

A = πr²

A = π(6)²

A = 36π

A = 113

If there is only 3/4 of the circle, then multiply the entire area by 3/4 to find the final answer.

113 x 3/4 = 84.8

Given, a = 1

common difference = 3

Eighth term = a+(n-1)d = 1+(8-1)3

= 1 + 21 = 22

The amount paid for the computer including sales tax is 0.918p

The price paid is given as:

Price = p

A 15% off means that he pays 85%.

So, we have:

Amount = 85% * p = 0.85p

A sales tax of 8% means:

Total = 0.85p * (1 + 8%)

Evaluate the product

Total = 0.918p

If the hockey team scores 9 goals in their next game, it means that; the mean would be the most affected.

We are given the data set as;

3, 6, 2, 1, 2, 3, 0, 4, 5, 1, 5, 4.

Let us rearrange in ascending order to get;

0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6.

The mean = (0 + 1 + 1 + 2 + 2 + 3 + 3 + 4 + 4 + 5 + 5 + 6)/12 = 3

Median = (3 + 3)/2 = 3

Mode = 1, 2, 3, 3, 5

Step-by-step explanation:

The balloon's vertical distance above the ground is 430 feet.

You look straight parallel to the ground. But when you have to watch something down, then you take your sight down by moving your head up.

The angle from horizontal to the point where you stopped your head is called the angle of depression.

From a hot-air balloon, Brody measures a 39° angle of depression to a landmark that's 532 feet away, measuring horizontally.

The angle of depression = 39°

The base = 532

We need to find the vertical distance consider perpendicular.

[tex]\rm Tan \theta = \dfrac{perpendicular}{base } \\\\\rm Tan 39 = \dfrac{perpendicular}{532} \\\\\rm Tan 39 \times 532 =perpendicular\\\\0.80 \times 532\\\\P = 430.80[/tex]

  (smallest, largest) = (B, C), (D, E), (G, J)

Step-by-step explanation:

Side lengths of a triangle are proportional to the sine of the opposite angle. In a triangle, a larger angle will always have a larger sine. That means the smallest angle is opposite the shortest side, and the largest angle is opposite the longest side.

__

The shortest side is 5 units, opposite angle B. The longest side is 7 units, opposite angle C.

The shortest side is 3 units, opposite angle D. The longest side is 5 units, opposite angle E.

The shortest side is 5 units, opposite angle G. The longest side is 5.1 units, opposite angle J.

Additional comment

Angles in a triangle may exceed 90°. The sine function actually is decreasing for angles above 90°. However, since the total of angles of a triangle must be exactly 180°, there cannot be two angles in a triangle such that the smaller angle has the larger sine.

[tex]x = - \frac{7}{4} \: \frac{1}{2} [/tex]

Step-by-step explanation:

[tex]8 {x}^{2} + 14x - 4x - 7 = 0 \\ 2x(4x + 7) - (4x + 7) = 0 \\ (4x + 7)(2x - 1) = 0[/tex]

Answer:

[tex]\large \text{$x_1$}=-\dfrac{7}{4}, \large \text{$x_2$}=\dfrac{1}{2}[/tex]

Step-by-step explanation:

Given: 8x² + 10x - 7 = 0

When factoring trinomials of the form ax² + bx + c:

1. Split the middle term:

⇒ 8 × -7 = -56 [multiply the leading coefficient and the last term]

⇒ 14, -4 [find the product factors that add to the middle term's coefficient]

⇒ 8x² + 14x - 4x - 7 = 0 [rewrite with those factors replacing the middle term.]

2. Factor by grouping:

⇒ 8x² + 14x - 4x - 7 = 0 [factor out 2x]

⇒ 2x(4x + 7) - 4x - 7 = 0 [factor out -1 or the negative sign]

⇒ 2x(4x + 7) -1(4x + 7) = 0 [factor out 4x + 7]

⟹ (4x + 7)(2x - 1) = 0

3. Separate into 2 cases:

Case 1:

⇒ 4x + 7 = 0 [subtract 7 from both sides]

⇒ 4x + 7 - 7 = 0 - 7

⇒ 4x = -7 [divide both sides by 4]

⇒ 4x ÷ 4 = -7 ÷ 4

⟹ x = [tex]\bold{-\dfrac{7}{4}}[/tex]

Case 2:

⇒ 2x - 1 = 0 [subtract 1 from both sides]

⇒ 2x - 1 + 1 = 0 + 1

⇒ 2x = 1 [divide both sides by 2]

⇒ 2x ÷ 2 = 1 ÷ 2

⟹ x = [tex]\bold{\dfrac{1}{2}}[/tex]
