Which of the following could be the equation of the graph shown below?
Answer:
According to the proposed interrogate, as well as the graph provided, the correct answers to such are identified as B. Y = -2x + 5 and C. 2x + y = 4.
Step-by-step explanation:
To evaluate such, a comprehension of linear Cartesian data is required:
Slope = rise/run. If there is a negative rise, the direction of the line is proportional to the left-hand side as it exponentially grows or augments in units.
Y-intercept: The peculiar point in which the linear data observed intersects the y-axis.
X-intercept: The peculiar point in which the linear data observed intersects the x-axis.
Since this is a negative linear, all negative slopes apply.
The interrogate states, “Check all that apply.” Thus, there may be more than one correct answer, shall such be disseminated.
A. Cannot be the answer as the line should have been a horizontal line contained within quadrants I and II on the Cartesian Plane.
B. Contains a negative slope, thus is disclosed as a correct answer.
C. This configuration is denoted in “Standard Form” or “General Form”. To convert this to “Slope-Intercept Form” the following must be executed mathematically:
2x + y = 4
Y = -2x + 4 <== Slope-Intercept Form (Contains a negative slope, thus considered a correct answer.
D. Likewise, this configuration is denoted in “Standard Form” or “General Form”. To convert this to “Slope-Intercept Form” the following must be executed mathematically:
X - y = 9
-y = -x + 9
Y = x - 9 <== Slope-Intercept Form (Cannot be considered as the correct answer, given the positive slope configuration, thus is marked out).
Thus far, as evaluated, the correct answers to the proposed interrogate, as according to the linear data provided in the Cartesian Plane is acknowledged, and henceforth disseminated, as B. Y = -2x + 5 and C. 2x + y = 4.

a precast concrete wall section is temporarily held by two cables as shown. knowing that the tension in cable bd is 900 n, determine the perpendicular distance, in meters, from point o to cable bd.
Rearranging the equation and solving for d, we get:
d = T / (W / g) = 900 N / (900 N / 9.8 m/s² * 9.8 m/s² / 9.8 m/s²)
But in fact, we need to knowing the mass of the wall section, it is not possible to determine the perpendicular distance "d" from point O to cable BD.
Determining Wall Distance To CableTo determine the perpendicular distance from point O to cable BD, we can use the equation for horizontal and vertical equilibrium, which states that the sum of all horizontal forces and the sum of all vertical forces must be equal to zero.
Let the perpendicular distance from point O to cable BD be "d". The vertical force acting on the wall section is given by the tension in cable BD, T = 900 N. The weight of the wall section can be calculated as W = m * g, where m is the mass of the wall section and g is the acceleration due to gravity (9.8 m/s²).The equation for vertical equilibrium can be written as:T - W = 0
900 N - (m * 9.8 m/s²) = 0
Solving for m, we get:m = 900 N / 9.8 m/s²
Using the mass, we can now calculate the weight of the wall section and substitute it back into the equation for vertical equilibrium:W = m * g = 900 N / 9.8 m/s² * 9.8 m/s²
900 N - W = 0
900 N - 900 N / 9.8 m/s² * 9.8 m/s² = 0
Rearranging the equation and solving for d, we get:d = T / (W / g) = 900 N / (900 N / 9.8 m/s² * 9.8 m/s² / 9.8 m/s²)
Unfortunately, without knowing the mass of the wall section, it is not possible to determine the perpendicular distance "d" from point O to cable BD.

Bella Company borrowed cash from conrad bank issuing a 30 day note at a face amount of 55,200 asume 360 day year determine the proceedsof the note at 5% and the discounted note at 5%
Step-by-step explanation:
The proceeds of the note can be calculated by multiplying the face amount by the interest rate. The interest rate for a 30-day note with a 360-day year can be calculated by dividing the annual interest rate by 360 and multiplying it by 30.
Proceeds of the note = 55,200 * (5/100/360 * 30) = 55,200 * (5/12) = 4,600
The discounted note can be calculated by subtracting the proceeds from the face amount.
Discounted note = 55,200 - 4,600 = 50,600
So, the proceeds of the note are $4,600 and the discounted note is $50,600.

Paisley and Damian are both driving along the same highway in two different cars to
a stadium in a distant city. At noon, Paisley is 315 miles away from the stadium and
Damian is 383 miles away from the stadium. Paisley is driving along the highway at a
speed of 42 miles per hour and Damian is driving at speed of 59 miles per hour. Let
P represent Paisley's distance, in miles, away from the stadium t hours after noon.
Let D represent Damian's distance, in miles, away from the stadium t hours after
noon. Write an equation for each situation, in terms oft, and determine whether
Paisley or Damian is closer to the stadium 5 hours after noon.
are
Using linear functions, it is found that:
Paisley's equation is: P(t) = 315 - 42t.Damian's equation is: D(t) = 383 - 59t.Damian is closer to the stadium 5 hours after noon.What is a linear function?A linear function is modeled by:
\(y = mx + b\)
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.Paisley is 315 miles away from the stadium, and driving at a speed of 42 miles per hour, hence for the linear equation for his distance after t hours, we have that:
m = -42, b = 315, then:
P(t) = 315 - 42t.
Damian is 383 miles away from the stadium, and driving at a speed of 59 miles per hour, hence for the linear equation for his distance after t hours, we have that:
m = -59, b = 383, then:
D(t) = 383 - 59t.
After 5 hours, their distances are:
P(5) = 315 - 42(5) = 105
D(5) = 383 - 59(5) = 88
D(5) < P(G), hence Damian is closer to the stadium 5 hours after noon.

the pro shop at the wildwood country club ordered two brands of golf balls. par one balls cost $2.10 each and the supra balls cost $1.00 each. the total cost of par one balls exceeded the total cost of the supra balls by $330.00 . if an equal number of each brand was ordered, how many dozens of each brand were ordered?
Step-by-step explanation:
x = number of par one balls ordered.
y = number of supra balls ordered.
2.10×x = 1.00×y + 330
2.1x = y + 330
y = 2.1x - 330
x = y (equal number was ordered).
so,
x = 2.1x - 330
0 = 1.1x - 330
330 = 1.1x
x = 330/1.1 = 300
y = x = 300
1 dozen = 12 pieces
so,
300/12 = 25 dozens
25 dozens balls were ordered from each brand.

Step-by-step explanation:
What happens if you can write a function as a composite in different ways? Do you get the same derivative each time? The Chain Rule says you should. Find
dy/dx if y=x by using the Chain Rule with y as a composite of the following functions. Complete parts (a) and (b) below.
Using the Chain Rule, we have: dy/dx = f'(g(x)) * g'(x) = 1 * 1 = 1.The derivative of y with respect to x is 1.
When we compose a function, it may be possible to write it in a variety of different ways. Differentiating such functions can result in different derivatives, but the Chain Rule indicates that the derivatives of the compositions should be the same regardless of how the function is written, if the function is continuous and differentiable.For instance, consider the function f(x) = sin(x²). It can be written as f(g(x)) where g(x) = x² and f(x) = sin(x). Furthermore, it can be written as f(h(x)) where h(x) = x² and f(x) = sin(x). These are both compositions of functions, but they are different compositions that lead to different derivatives.However, if the function is a composite of differentiable functions, the Chain Rule tells us that the derivative of a composite function is the derivative of the outer function multiplied by the derivative of the inner function.
To find dy/dx if y = x using the Chain Rule with y as a composite of the following functions, we must first rewrite y as a composite function: y = f(g(x)) where g(x) = x and f(x) = x. This composite function can be written in a variety of different ways, such as y = f(h(x)) where h(x) = x and f(x) = x, or y = f(k(x)) where k(x) = x and f(x) = x. However, regardless of how we write it, the Chain Rule tells us that the derivative of y is equal to the derivative of the outer function (f(x) = x) multiplied by the derivative of the inner function (g(x) = x).
