The line perpendicular to the line with an equation y = 6x have a slope of -1/6
What is an equation?An equation is an expression that contains numbers and variables linked together by mathematical operations of addition, subtraction, multiplication, division and exponents. An equation can either be linear, quadratic, cubic, depending of the degree of the variable.
The slope intercept form of a linear equation is:
y = mx + b
Where m is the rate of change and b is the y intercept.
Two lines are perpendicular if the product of their slopes is -1.
Line M goes through the points (0, 0) and (1, 6). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\substituting:\\\\y-0=\frac{6-0}{1-0} (x-0)\\\\y=6x[/tex]
The slope of the line y = 6x is 6.
The line perpendicular to y = 6x have a slope of -1/6

in 1991, the moose population in a park was measured to be 3270. by 1997, the population was measured again to be 4770. if the population continues to change linearly: a.) find a formula for the moose population, , in terms of , the years since 1990
Step 1: Calculate the rate of change in the moose population.
The rate of change in the moose population can be calculated by subtracting the 1991 population (3270) from the 1997 population (4770) and dividing the result by the number of years (7).
Therefore, the rate of change in the moose population is (4770 - 3270) / 7 = 700 moose/year.
Step 2: Find the formula for the moose population in terms of the years since 1990.
The formula for the moose population in terms of the years since 1990 is P(t) = 3270 + 700t, where t is the number of years since 1990.

Ravi had a rope. He used 45 cm of the rope to tie a parcel
He then cut the remaining rope equally into 4 pieces. Each piece was 65 cm long. (A)
As per unitary method,
a) The length of the rope left after tying the parcel 260 cm
b) The initial length of the rope was 305cm.
The unitary method is a mathematical tool used to solve problems involving the partition of a whole into parts.
(a) To find the length of the rope left after tying the parcel, we subtract the length of the rope used to tie the parcel from the initial length of the rope. The length of the rope left is:
=> Initial length of the rope - Length of rope used to tie the parcel = Length of rope left
We are told that Ravi used 45cm of the rope to tie a parcel. Therefore, the length of rope left can be expressed as:
Initial length of the rope - 45 = Length of rope left
(b) To find the initial length of the rope, we add the length of the rope used to tie the parcel to the length of the rope left.
We know that the length of the rope left is divided into 4 pieces of 65cm each. Therefore, the total length of the rope left is
=> 4 x 65 = 260cm.
We can now use this information to find the initial length of the rope:
Length of rope left + Length of rope used to tie the parcel = Initial length of the rope
260 + 45 = 305cm
Complete Question:
Ravi had a rope. He used 45cm of the rope to tie a parcel. He then cut the remaining rope equally into 4 pieces. Each piece was 65cm long.

a scatter plot shows multiple select question. if an obvious association exists between two variables. pairs of observations (x1, y1) . . . (xn, yn) on an x-y graph. only nonlinear relationships. only linear relationships..
A linear relationship can be expressed by the equation y = mx + b, where m is the slope of the line and b is the y-intercept.
This equation can be used to calculate the relationship between two variables, x and y. For example, if we have two sets of data points (x1, y1)…(xn, yn) we can calculate the slope m and the y-intercept b as follows:
m = (sum of (x_i - x_mean)*(y_i - y_mean))/(sum of (x_i - x_mean)^2)
b = y_mean - m*x_mean
Where x_mean and y_mean are the sample means of the x and y variables respectively.
Once we have calculated m and b, we can use the equation y = mx + b to describe the linear relationship between x and y. We can also use this equation to predict the value of y for a given x value. For example, if m = 2 and b = 0, then the equation becomes y = 2x and we can predict that when x = 1, y = 2.
In contrast, a nonlinear relationship is one which cannot be described by the equation y = mx + b, as the relationship between x and y is not linear. Instead, a nonlinear relationship is one in which the relationship between x and y is described by a more complex equation, such as y = ax^2 + bx + c.
To summarise, a linear relationship between two variables can be described by the equation y = mx + b, where m is the slope and b is the y-intercept, while a nonlinear relationship is one which cannot be described by this equation and is instead described by a more complex equation.

This inequality can be used to represent the maximum weight that a stepladder can hold, which is 250 pounds. In other words, the weight, w, must be less than or equal to 250 pounds.
The weight, w, must be less than or equal to 250 pounds. This inequality can be used to represent the maximum weight that a stepladder can hold, which is 250 pounds. In other words, if the weight of the object being placed on the stepladder is greater than 250 pounds, it is not safe to use the stepladder. This inequality helps to ensure the safety of the person using the stepladder, as it limits the amount of weight that can be placed upon it. Furthermore, it also helps to protect the stepladder itself, as it prevents it from being overloaded with too much weight, which could cause it to break or malfunction. In conclusion, the inequality w ≤ 250 represents the maximum weight that a stepladder can safely hold.

Answer: The area of right triangle ABC can be found using the formula (1/2)bh, where b is the length of the base and h is the height. Since the base of the triangle is 5 units and the area is 12.5 square units, the height must be 2.5 units.
Knowing that point C is on the line x = -2, we can use the height of 2.5 units to find the y-coordinate of point C.
Starting from the line y = 2, moving 2.5 units down will give us a y-coordinate of y = 2 - 2.5 = -0.5.
So, a possible y-coordinate of point C is -0.5.
Step-by-step explanation:
Answer:

Step-by-step explanation:
A = 1/2 (b)(h)
12.5 = 1/2 (5)(h)
Multiply both sides by 1/2 or 2 to cancel out the fraction
2 x 12.5 = 1/2 (5)(h) x 2
25 = 5h
Divide both sides by 5 to get h on its own
25/5 = 5h/5
h = 5
