Answer:
y= -3x+4
Step-by-step explanation:
You need to simplify down to y=mx+b by dividing -2 from both sides:
-2/-2= cancels out making y
6/-2= -3
-8/-2= 4
New equation:
y= -3x+4

5. The table shows the number of pounds, x, of coffee ordered and the total price, y, in dollars, of each order. X 5 6 7 10 y $35 $42 $49 $70 Which best represents the units for the rate of change (rise over run) in the table? a.dollars. b.dollars per pound. c.pounds b.pounds per dollar
The table shows the number of pounds, x, of coffee ordered and the total price, y, in dollars, of each order. X 5 6 7 10 y $35 $42 $49 $70 Which best represents the units for the rate of change (rise over run) in the table? a.dollars. b.dollars per pound. c.pounds b.pounds per dollar
To find the units for the rate of change (rise over run), we need to determine the change in y (rise) divided by the change in x (run) for any two points in the table.
Let's choose the first and last points in the table, (5, $35) and (10, $70), respectively. The change in y is $70 - $35 = $35, and the change in x is 10 - 5 = 5. So the rate of change (rise over run) is:
rise/run = $35/5 = $7
Therefore, the best representation for the units of the rate of change is dollars per pound, as the rate of change indicates how much the price changes for every pound of coffee ordered. So the answer is (b) dollars per pound.

Given the following historical demand and forecast, calculate the Tracking Signal in Week 3:
Week 1 Demand: 50 Forecast: 49
Week 2 Demand: 54 Forecast: 56
Week 3 Demand: 58 Forecast: 60
The Tracking Signal in Week 3 is -1.8.
The Tracking Signal in Week 3 can be calculated by using the following formula:
Tracking Signal = (Sum of Forecast Errors) / (Mean Absolute Deviation)
First, we need to calculate the forecast errors for each week:
Week 1 Forecast Error = Actual Demand - Forecast = 50 - 49 = 1
Week 2 Forecast Error = Actual Demand - Forecast = 54 - 56 = -2
Week 3 Forecast Error = Actual Demand - Forecast = 58 - 60 = -2
Next, we need to calculate the Mean Absolute Deviation (MAD):
MAD = (|1| + |-2| + |-2|) / 3 = (1 + 2 + 2) / 3 = 5 / 3 = 1.67
Finally, we can calculate the Tracking Signal:
Tracking Signal = (1 + -2 + -2) / 1.67 = -3 / 1.67 = -1.8
Therefore, the Tracking Signal in Week 3 is -1.8.

What’s the value of x?
Answer:
The value of [tex]x[/tex] is [tex]55\textdegree[/tex].
Step-by-step explanation:
A straight line is equal to 180 degrees.
So any angles that forms on the same side of a straight line always add to 180 degrees.
We are given an angle of [tex]130\textdegree[/tex] on the exterior of the triangle.
Lets call the angle next to that [tex]\angle B[/tex].
We can conclude that
[tex]\angle B+130=180[/tex]
[tex]\angle B=180-130[/tex]
[tex]\angle B=50[/tex]
The sum of the interior angles in a triangle is 180 degrees. This is because a triangle is a polygon with three sides and three angles, and the sum of the angles in any polygon can be found by using the formula:
sum of interior angles = (n - 2) x 180 degrees
Note: n is the number of sides.
A triangle has 3 sides. So substituting 3 in for n gives us
(3 - 2) x 180 degrees = 180 degrees
So the sum of the interior angles in a triangle is always 180 degrees.
[tex]x\textdegree=180\textdegree-75\textdegree-50\textdegree\\x\textdegree=55\textdegree[/tex]

let a (x)=3x^3-4x^2+x, and b(x)=x^2+2
Divide polynomials with remainders
a(x) = b(x) * (3x² - 10x + 21) + (8x - 8)
Polynomial Division with RemaindersTo divide the polynomial a(x) by b(x), we can use long division as follows:
3x - 6
-------------------
x² + 2 | 3x² - 4x² + x
- (3x³ + 0x²)
---------------
-4x² + x
- (-4x² - 8)
-------------
8x - 8
Therefore, the quotient is 3x - 6, and the remainder is 8x - 8.
We can write the result of the division as:a(x) = b(x) * (3x - 6) + (8x - 8)
Alternatively, we can use synthetic division to get the same result:-2 | 3 -4 1 0
| -6 20 -42
|-------------
| 3 -10 21 -42
The numbers on the bottom row represent the coefficients of the quotient, which are 3, -10, 21. The last number on the bottom row, -42, is the remainder. Therefore, the quotient is:
3x² - 10x + 21

Find & particular solution Yp of the following equation using the Method of Undetermined Coefficients. Primes denote the derivatives with respect to x
y" -y' - 2y = 8x + 5 A particular solution is Yp(x) = ?
(a) The particular solution, y_p is 7
(b) y_p is -4x
(c) y_p is -4x + 7
(d) y_p is 8x + (7/2)
To find a particular solution to a differential equation by inspection - is to assume a trial function that looks like the non-homogeneous part of the differential equation.
(a) Given y'' + 2y = 14.
Because the no non-homogeneous part of the differential equation, 14 is a constant, our trial function will be a constant too.
Let A be our trial function:
We need our trial differential equation y''_p + 2y_p = 14
Now, we differentiate y_p = A twice, to obtain y'_p and y''_p that will be substituted into the differential equation.
y'_p = 0
y''_p = 0
Substitution into the trial differential equation, we have.
0 + 2A = 14
A = 6/2 = 7
Therefore, the particular solution, y_p = A is 7
(b) y'' + 2y = −8x
Let y_p = Ax + B
y'_p = A
y''_p = 0
0 + 2(Ax + B) = -8x
2Ax + 2B = -8x
By inspection,
2B = 0 => B = 0
2A = -8 => A = -8/2 = -4
The particular solution y_p = Ax + B
is -4x
(c) y'' + 2y = −8x + 14
Let y_p = Ax + B
y'_p = A
y''_p = 0
0 + 2(Ax + B) = -8x + 14
2Ax + 2B = -8x + 14
By inspection,
2B = 14 => B = 14/2 = 7
2A = -8 => A = -8/2 = -4
The particular solution y_p = Ax + B
is -4x + 7
(d) Find a particular solution of y'' + 2y = 16x + 7
Let y_p = Ax + B
y'_p = A
y''_p = 0
0 + 2(Ax + B) = 16x + 7
2Ax + 2B = 16x + 7
By inspection,
2B = 7 => B = 7/2
2A = 16 => A = 16/2 = 8
The particular solution y_p = Ax + B
is 8x + (7/2)

A polynomial is an expression consisting of variables and coefficients and factoring is the process of breaking down a polynomial into simpler units
A polynomial is an expression consisting of variables and coefficients, which are combined using only addition, subtraction, and multiplication. For example, 3x^2 + 2x - 1 is a polynomial, where x is the variable, 3 and 2 are coefficients, and ^2 and ^1 are exponents.
Factoring is the process of breaking down a polynomial into simpler units, which can be multiplied together to obtain the original polynomial. The simplest units are usually linear expressions, which have the form ax + b, where a and b are coefficients. For example, the polynomial 3x^2 + 2x - 1 can be factored into (3x - 1)(x + 1) by identifying two linear expressions that when multiplied together produce the original polynomial.
Factoring is an important tool in algebra, as it can help to simplify expressions, solve equations, and identify the roots of a polynomial.

If the angles of a triangle are in the ration of 3 : 4 : 5, find them.
Answer:
the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.
Step-by-step explanation:
Let's denote the angles of the triangle as 3x, 4x, and 5x, where x is a constant.
Since the sum of the angles of a triangle is 180 degrees, we can write the following equation:
3x + 4x + 5x = 180
Simplifying this equation, we get:
12x = 180
Dividing both sides by 12, we get:
x = 15
Therefore, the angles of the triangle are:
3x = 3(15) = 45 degrees
4x = 4(15) = 60 degrees
5x = 5(15) = 75 degrees
So the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.
Javier is standing at a distance from a flagpole. He sights the bottom of the flagpole at a 4°
angle of depression and the top of the flagpole at a 25°
angle of elevation. If Javier is 6 feet tall, what is the total height, to the nearest foot, of the flagpole?
Answer: To find the height of the flagpole, we can use the fact that the angles of depression and elevation are complementary angles, meaning that they add up to 90°.
Let's call the height of the flagpole "h". Then, we have:
h - 6 = h * tan(4°) (the height difference between Javier and the bottom of the flagpole)
and
h = 6 + h * tan(25°) (the height of the top of the flagpole as seen by Javier).
By substituting the first equation into the second, we can find h:
h = 6 + h * tan(25°)
h = 6 + h / tan(65°)
h * tan(65°) = 6 + h
h * tan(65°) - h = 6
h = 6 / (tan(65°) - 1)
Using a calculator, we find that h = approximately 43.3 feet. Rounding to the nearest foot, the height of the flagpole is 43 feet.
