The points represented by the (x, y) coordinate pairs all lie on line "k". These are the points: (1,3), (2, 1), (3,-1). (4.-3), and (5,-5). What is the slope of line k? A.2 B.5 C.-3 D.-2

Answer:a
Step-by-step explanation:
Bsnanna
If the points (1,3), (2, 1), (3,-1). (4.-3) lie on line k, then the slope of line k is -2
Option D is the correct choice
The points that lie on the line k are:
(1,3), (2, 1), (3,-1). (4.-3), and (5,-5).
We can find the slope of the line k by picking any two points on the line
The slope m of a line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
On the line k, let us select the points (1,3) and (2, 1)
x₁ = 1, y₁ = 3, x₂ = 2, y₂ = 1
[tex]m = \frac{1-3}{2-1} \\\\m= \frac{-2}{1}\\\\m= -2[/tex]
Therefore, the slope of the line k is -2

The common ratio of a geometric sequence is 3 and the 8th term is 4,374. What is the 4th term in this sequence?
Answers
Answer:
the first term is a1
the 8th term is a8
the 4th term is a4
we have:
[tex]a8=a1.3^{7}\\\\<=>4374=a1.3^{7}\\\\<=>a1=2[/tex]
with a1 = 0,002 => a4 = a1.3³ = 2.27 =54
Step-by-step explanation:
The 4th term of the given geometric sequence is 54.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
The nth term of a GP is given as a[tex]r^{n-1}[/tex]
As per the given,
Common ratio r = 3
8th term = 4374
a(3)⁸⁻¹ = 4374
a = 2
The 4th term will be as, 2 x (3)⁴⁻¹ = 54
Hence "The 4th term of the given geometric sequence is 54".

Candace makes a sugar-water mixture for hummingbirds. She knows the amount of sugar used in the mixture is proportional to the amount of water used.
Which of the following could represent the relationship between the amount of sugar and water Candace should use in the mixture?
Answers
Answer:
the first image (the image with the upward sloping line)
Step-by-step explanation:
If the amount of sugar used in the mixture is proportional to the amount of water used, as more water is used, the more sugar is used. So, as more water is used, more sugar is used.
If the amount of water used is constant regardless of the amount of sugar, the appropriate graph would be the second graph. the graph with the straight line

A forest covers 73,000 acres. A survey finds that 0.2% of the forest is old-growth trees. How many
acres of old-growth trees are there?
There are acres of old-growth trees.
Type an integer or a decimal)
Answers
Answer:
143 acres.
Step-by-step explanation:
To find how many acres of old-growth trees there are, we need to find what 0.2% of 73,000 is.
To find a percent of a number, multiply the percent by the number.
0.2% is equal to 0.002.
73,000 x 0.002 = 143
So, 143 acres of the forest is old-growth trees.
