Answer:
They are both functions, linear equations, and they both have a constant rate if that is what you are asking.
Step-by-step explanation:
Constant rate is k in y=kx. For the equation on the left, 2 is the constant rate and for the equation on the right is 0.5. They are both linear equations because if you line them up on a graph, it will show a straight line. And for every input should give one output. Hope this helps! Have a great day!

Answers
Answer:
x=8
Step-by-step explanation:
48=5(2x-7)+3
Use the distributive property
48=10x-35+3
Combine like terms
48=10x-32
Add 32 to both sides to cancel out the negative 32
80=10x
x=8
Answer:
x = 8
Step-by-step explanation:
Step 1: Write equation
48 = 5(2x - 7) + 3
Step 2: Solve for x
Distribute 5: 48 = 10x - 35 + 3Combine like terms: 48 = 10x - 32Add 32 to both sides: 80 = 10xDivide both sides by 10: 8 = xRewrite: x = 8Step 3: Check
Plug in x to verify it's a solution.
48 = 5(2(8) - 7) + 3
48 = 5(16 - 7) + 3
48 = 5(9) + 3
48 = 45 + 3
48 = 48

in δghi, h = 9.3 cm, g = 5.8 cm and ∠g=50°. find all possible values of ∠h, to the nearest 10th of a degree.
Answers
The given conditions cannot form a triangle. The sum of the angles in a triangle must be 180 degrees. In this case, the sum of the angles is 100 degrees (50 + 50). Therefore, there is no possible value for angle h.
Here is the calculation:
Angle G + Angle H + Angle I = 180
50 + Angle H + Angle I = 180
Angle H + Angle I = 180 - 50
Angle H + Angle I = 130
Since the sum of angle h and angle i is 130 degrees, there is no possible value for angle h that will result in a triangle with a total angle measure of 180 degrees.

There are 9 water bottles in the refrigerator. I add 3 full boxes of water bottles to the refrigerator. Then i had two more boxes that each had 1 fewer bottle then the full box. Now that i'm done there's 67 bottles. What equation would find the number of bottles in a full box
Answers
Answer:
There are twelve 12 bottles in one full box.
Step-by-step explanation:
From the given information:
suppose there are 9 water bottles in the refrigerator,
and 3 full boxes of water are being added, we do not know the total number of bottles in a box, so let's represent it by b
i.e. 3b
However, two more boxes are being added which had 1 fewer bottle than the full box.
i.e. 2(b-1)
Now to determine the number of bottles in a full box, we have:
9 + 3b +2(b-1) = 67
9 + 3b + 2b - 2 = 67
5b + 7 = 67
5b = 67 - 7
5b = 60
b = 60/5
b = 12
Hence, there are twelve 12 bottles in one full box.

Answer:
Numbers: 6 and -2
Step-by-step explanation:
Equations
This question can be solved by inspection. It's just a matter of factoring 12 into two factors that sum 4. Both numbers must be of different signs and they are 6 and -2. Their sum is indeed 6-2=4 and their product is 6*(-2)=-12.
However, we'll solve it by the use of equations. Let's call x and y to the numbers. They must comply:
[tex]x+y=4\qquad\qquad [1][/tex]
[tex]x.y=-12\qquad\qquad [2][/tex]
Solving [1] for y:
[tex]y=4-x[/tex]
Substituting in [2]
[tex]x(4-x)=-12[/tex]
Operating:
[tex]4x-x^2=-12[/tex]
Rearranging:
[tex]x^2-4x-12=0[/tex]
Solving with the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
With a=1, b=-4, c=-12:
[tex]\displaystyle x=\frac{-(-4)\pm \sqrt{(-4)^2-4(1)(-12)}}{2(1)}[/tex]
[tex]\displaystyle x=\frac{4\pm \sqrt{16+48}}{2}[/tex]
[tex]\displaystyle x=\frac{4\pm 8}{2}[/tex]
The solutions are:
[tex]\displaystyle x=\frac{4+ 8}{2}=6[/tex]
[tex]\displaystyle x=\frac{4- 8}{2}=-2[/tex]
This confirms the preliminary results.

On November 1, 2020 Starstruck Inc. signed a $300,000,8 month, 8% note payable. At due date, the principal and interest will be paid. Calculate the amount of interest expense that Starstruck Inc. should report on its income statement for the year ended December 31,2021. (round to the nearest dollar) Answer: \$.
Answers
Starstruck Inc. should report approximately $8,767 as the amount of interest expense on its income statement for the year ended December 31, 2021.
To calculate the amount of interest expense that Starstruck Inc. should report on its income statement for the year ended December 31, 2021, we need to determine the interest accrued for the 14-month period from November 1, 2020, to December 31, 2021.
The formula to calculate interest expense is:
Interest Expense = Principal * Interest Rate * Time
Principal = $300,000
Interest Rate = 8% per year
Since the note is an 8-month note, we need to calculate the interest for the 14-month period.
We can use the following formula to calculate the time in years:
Time = Number of days / Days in a year
Number of days from November 1, 2020 to December 31, 2021 = 426 days
Days in a year = 365 days
Time = 426 / 365
Now we can calculate the interest expense:
Interest Expense = $300,000 * 8% * (426 / 365)
Interest Expense ≈ $8,767.12

solve the dual of the siven prislem usin the dual simplex algorithm
Answers
If you have access to a linear programming solver or software like Excel Solver or MATLAB's Optimization Toolbox, you can enter the dual problem and use the solver to obtain the optimal solution.
To solve the dual of the given problem using the dual simplex algorithm, we first need to rewrite the primal problem in standard form. The primal problem is as follows:
Maximize: z = 11x + x + 6w
Subject to:
6x + 15x - 3w ≥ 60
3x + 2x + w ≤ 21
2x + 3x - w = 34
x ≥ 0, y ≥ 0, w ≥ 0
The dual problem will have the following form:
Minimize: w = 60y + 21z + 34u
Subject to:
6y + 3u + 2v ≥ 11
15y + 2u + 3v + u + v ≥ 1
-3y + v = 6
y ≥ 0, u ≥ 0, v unrestricted
Now, we can apply the dual simplex algorithm to solve the dual problem. The steps involved in the dual simplex algorithm include:
Start with an initial feasible solution.
Check for optimality.
If not optimal, select a pivot column and pivot row.
Perform row operations to make the pivot element 1 and all other elements in the pivot column 0.
Repeat steps 2-4 until the optimal solution is reached.
The detailed calculations and iterations involved in the dual simplex algorithm can be quite lengthy and involve complex matrix operations. It would be best to use a specialized software or linear programming solver to perform these calculations accurately and efficiently.
