Answer:

Step-by-step explanation:

This Sequence is  Geometric Progression

a = 16

r = 8/16 = 1/2

nth term = ar^(n-1) = 16*(1/2)^(n-1)

The nth term of the geometric sequence 16, 8, 4, 2, 1 can be found using the formula an = 16 * (1/2)^(n-1), where n is the position of the term in the sequence.

The sequence given is 16, 8, 4, 2, 1, which is a geometric sequence where each term is half of the previous term. This means the common ratio r is 1/2. The nth term of a geometric sequence is given by the formula a_n = a_1 * r^(n-1), where a_1 is the first term and r is the common ratio.

To find the nth term for our sequence, we plug in the values: a_1 = 16 and r = 1/2. Thus, the formula for the nth term becomes an = 16 * (1/2)^(n-1).

The simplified expression is

[tex]\frac{4}{5}(\frac{1}{4}c-5)=\frac{c}{5}-4[/tex]

Step-by-step explanation:

Given expression is

[tex]\frac{4}{5}(\frac{1}{4}c-5)[/tex]

To simplify the given expression:

[tex]\frac{4}{5}(\frac{1}{4}c-5)[/tex]

[tex]\frac{4}{5}(\frac{1}{4}c-5)=(\frac{4}{5}\times \frac{1}{4}c)-(\frac{4}{5}\times 5)[/tex] ( here using the distributive property )

[tex]=(\frac{1}{5}c)-(4\times 1)[/tex] (simplify the factors )

[tex]=\frac{1}{5}c-4[/tex] or

[tex]=\frac{c}{5}-4[/tex]

Therefore the simplified expression is

[tex]\frac{4}{5}(\frac{1}{4}c-5)=\frac{c}{5}-4[/tex]

The correct answer is "no solution."

Let's first rewrite the second equation in the system in slope-intercept form (y = mx + b) to make it easier to work with:

[tex]\[ -5y = 10x + 20 \][/tex]

Divide both sides by -5:

[tex]\[ y = -2x - 4 \][/tex]

Now we have the system of equations:

[tex]\[ y = -2x + 5 \][/tex]

[tex]\[ y = -2x - 4 \][/tex]

To find the solution to the system, we can set the two equations equal to each other since they both equal y:

[tex]\[ -2x + 5 = -2x - 4 \][/tex]

Now, we can solve for x:

[tex]\[ 5 = -4 \][/tex]

This equation is not true, which means there is no value of x that satisfies both equations simultaneously. Therefore, the system has no solution.

Answer:

Angle 1:  100

Angle 2:  80

Step-by-step explanation:

A linear pair of angles is formed when two lines intersect.  The measure of a straight angle is 180 degrees, so a linear pair of angles is equal to 180 degrees.

Angle 1: x

Angle 2: (x * 3/4) + 5

x + (x * 3/4) + 5 = 180

x + 3/4x + 5 = 180

1 3/4x + 5 - 5 = 180 - 5

1 3/4x = 175

1 3/4x / 1 3/4 = 175 / 1 3/4

x = 100

Check:

(x * 3/4) + 5

(100 * 3/4) + 5

75 + 5

80

100 + 80 = 180

To find the measure of both angles that form a linear pair, set up an equation and solve for x.

To find the measure of both angles, let's assume that one angle is x degrees. According to the given information, the other angle is 3/4 of x degrees plus 5. So the measure of the other angle is (3/4)x + 5 degrees. Since the two angles form a linear pair, their measures sum up to 180 degrees. Therefore, we can write the equation: x + (3/4)x + 5 = 180. Solving this equation, we can find the value of x and then calculate the measures of both angles.

Answer:

x = 2, y = -1

Step-by-step explanation:

2x + 3y = 1.....(1)

5x + 2y = 8.....(2)

multiply equation (1) by 5 and equation (2) by 2

10x + 15y = 5 .......(3)

10x + 4y = 16......(4)

solving by elimination method

we subtract equation (4) from (3)

hence ...

11y = -11

dividing both sides by 11

y = -1

substituting y = -1 in equation (1) to solve for the value of x

2x + 3(-1) = 1

2x - 3 = 1

rearranging,

2x = 3 + 1

2x = 4

dividing both sides by 2

x = 2

The coordinates of a point on the directed segment from (3,-2) to (8,0) that divides it into a ratio of 3:1 is (6.75, -0.5). The correct option is A.

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

Let the line be represented as AB, therefore, the coordinates of points A and B are (3,-2) and (8,0), respectively. The coordinate of the point m that divides the line AB in a ratio of 3:1 is,

x = [(x₂×m)+(x₁×n)]/(m+n)

x = [(8×3)+(3×1)]/(3+1)

  = (24+3)/4

  = 6.75

y = [(y₂×m)+(y₁×n)]/(m+n)

y = [(0×3)+(-2×1)]/(3+1)

  = (0-2)/4

  = -0.5

Final answer:

The coordinates of the point that divides the directed segment from (3,-2) to (8,0) in the ratio of 3:1 are a) (6.75, -0.5), using the section formula.

Explanation:

When finding the coordinates of a point on a directed segment that divides it into a specific ratio, such as 3:1, the formula for the section formula in coordinate geometry is used. This formula allows us to calculate the coordinates of the point that divides the segment internally or externally in a given ratio (m:n) using the coordinates of the endpoints (x1,y1) and (x2,y2). The formula for the point (x, y) that divides the segment internally in the ratio m:n is:

x = (mx2 + nx1) / (m + n)

y = (my2 + ny1) / (m + n)

For the directed segment from (3, -2) to (8, 0) and a ratio of 3:1, we find the point by this method:

x = (3×8 + 1×3) / (3 + 1) = (24 + 3) / 4 = 27 / 4 = 6.75

y = (3×0 + 1×(-2)) / (3 + 1) = (0 - 2) / 4 = -2 / 4 = -0.5

Thus, the coordinates of the point that divides the segment in the ratio 3:1 are a) (6.75, -0.5).

Answer:Briana needs 562likes to reach 2000

Step-by-step explanation:

The number of likes Briana has = 1438

The number of likes Briana wants to reach = 2000

The remaining of likes she needs= 2000-1438 = 562

Hence, Briana needs 562 more likes to reach 2000likes on her picture

Final answer:

Briana needs 562 more likes to reach 2,000 likes on her dog's picture, calculated by subtracting her current likes from the target amount.

Explanation:

Briana currently has 1,438 likes on a picture of her dog dressed as a superhero. To determine how many more likes Briana needs to reach 2,000 likes, we perform a simple subtraction operation:

2,000 (desired amount of likes) - 1,438 (current amount of likes) = 562 more likes needed.

Therefore, Briana needs 562 additional likes to reach her goal of 2,000 likes on the picture of her dog.

A tree diagram is a form of graphical representation that visually displays possible outcomes of an experiment or event. It is particularly useful in solving complex probability problems. An example would be if you were to draw balls from an urn multiple times and wanted to visualize all the possible outcomes.

A tree diagram is a graphical representation used to determine the outcomes of an experiment. It consists of multiple branches, typically representing different possible outcomes or choices.

As an example, let's consider an urn with 11 balls: 3 red and 8 blue. If you were to draw two balls, one at a time, with replacement (putting the first ball back before the second draw), a tree diagram would show all possible outcomes. Your first set of branches would represent the color of the first ball drawn (red or blue) and from each of those branches, a second set would signify the color of the second ball drawn.

So branch one could show red for the first draw, and from that branch you would have two further branches, red and blue, showing the possibilities for the second draw. The same would be done for the first draw being blue. This tree diagram illustrates the different scenarios of this experiment.

Step-by-step explanation:

The solution is x = 2 and y = -11

Solution:

Given system of equations are:

x + y = -9 --------- eqn 1

5x - 2y = 32 ------------- eqn 2

We have to solve the system of equations

We can solve the system by substitution method

From eqn 1,

x + y = -9

Isolate "y" to one side

y = -9 - x ---------- eqn 3

Substitute eqn 3 in eqn 2

5x -2(-9 - x) = 32

5x + 18 + 2x = 32

Combine the like terms

7x = 32 - 18

7x = 14

x = 2

Substitute x = 2 in eqn 3

y = - 9 - 2

y = -11

Final answer:

The equation 'twice a number minus seven equals eight greater than three times the number' simplifies to 2x - 7 = 3x + 8, which has one solution: x = -15.

Explanation:

The original question asks us to solve an algebraic equation where twice a number minus seven is equal to eight greater than three times that number.

To translate this into an algebraic expression, let the unknown number be x.

This gives us the equation 2x - 7 = 3x + 8.

To solve this equation, we can subtract 2x from both sides to get -7 = x + 8 and then subtract 8 from both sides to isolate x, resulting in x = -15.

To answer part B, this type of linear equation will only have one solution because it’s a linear equation with a non-zero coefficient in front of the variable x.
