Answer:
A.
Step-by-step explanation:
The required stories that are models of the given expression -6 + 3x = 2 + 4x are given in A and B. Both options are correct.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Option A,
At 5 p.m., the temperatures recorded at two weather stations in Antarctica are -6 degrees and 2 degrees. The temperature changes at the same constant rate, x degrees per hour, throughout the night at both locations. The temperature at the first station 3 hours after this recording is the same as the temperature at the second station 4 hours after this recording.
So from the above statement,
The equation modeled is given as
-6 + 3x = 2 + 4x
The above expression is equivalent to the given statement. So story mentioned in option A matches the given equation.
Similarly,
The equation formed in Option B also matches the given equation.
Thus, both options are correct.

Alisha used the Given table to find the slope of a linear relationship . Find her Error and correct it :
Alisha's Answer:
The Slope ( m ) = 6
Answers
Answer:
Please mark me as a brainlist.............
Thank you.....
Answer:
Alisha might have not taken respective input values with the output values and the correct slope is 3.
Step-by-step explanation:
The general form of a linear relationship is given by the equation
[tex]y = mx+b[/tex]
Here m is the rate of change of the linear relationship which is calculated as:
[tex]m = \frac{change\ in\ y}{change\ in\ x}[/tex]
Change in y is given by the difference of two outputs and x is given by difference of two inputs
So taking the set of outputs and inputs
(1,2) and (2,5)
[tex]m = \frac{5-2}{2-1}\\m = \frac{3}{1}\\m = 3[/tex]
Alisha might have not taken respective input values with the output values and the correct slope is 3.

2. Move the constants to the other side
-3-35=12y-10y
3. Subtract the terms

4. Divide by 2 to get y by itself
y=-19
Answer:
y = -19
Step-by-step explanation:
-3 = 12y -5(2y - 7)
distribute -5 to (2y -7)
-3 = 12y - 10y + 35
subtract 35 from both sides and simplify
-38 = 2y

The corner market sells potatoes at a rate of 1/2 dollars per potato.
1. Amanda is only able to spend $5 on potatoes. What is the most number of potatoes she can buy?
2. Sam wants to buy 15 potatoes. How much will that cost him?
Answers
Answer:
The cost of 15 potatoes is $7.50
Step-by-step explanation:
The potatoes are sold at a rate of $0.5 per potato.
1. Given Amanda can only spend $5 on potatoes at that price, she can buy at most $5 / 0.5 = 10 potatoes.
Amanda can buy at most 10 potatoes
2. Sam wants to buy 15 potatoes at that very same price. The cost of 15 potatoes is:
15 * $0.5 = $7.50
The cost of 15 potatoes is $7.50

The natural numbers are also known as the counting numbers or the ordering numbers and includes positive whole numbers from 1 and above
b) A digit is a number from 0 to 9, which can be used singly or combined to form a number
There are two digits each in 12 and 11, therefore, there are a total of 4 digits in both numbers
c) The sum of all the digits is given as follows;
The sum of the digits = 1 + 2 + 1 + 1 = 5.

6. Janet makes scarves to sell at the craft fair. Each scarf requires 2.5 yards of yarn. A. At the fabric store, yarn is sold by the foot. If Janet wants to make 84 scarves, how many feet of yarn must she buy?
Answers
Answer:
610 feet
Step-by-step explanation:
From the question :
1 scarf = 2.5 yards of yarn
84 scarves = x yards
Cross Multiply
1 scarf × x yards = 84 × 2.5 yards
x yards = 210 yards
Hence, 84 scarves require 210 yards
Converting yards to feet
1 yard = 3 feet
210 yards = x feet
x feet × 1 yard = 210 yards × 3 feet
x feet = 210 yards × 3 feet/1 yards
x feet = 610 feet
Hence, if Janet wants to make 84 scarves, she need to buy 610 feet of yarn

Answers
Answer:
(x + 5)^2 = (5 - 3)^2
Step-by-step explanation:
Given the equation;
x^2 + 10x + 22 = 13
We have;
x^2 + 10x = 13 - 22
x^2 + 10x = -9
Adding half of 10 to both sides and completing the square as usual, we have;
(x + 5)^2 = 5^2 + (-9)
(x + 5)^2 = (5 - 3)^2
The rewritten equation, after completing the square, is
(x - 3/2)² = -79/4.
To rewrite the equation x² + 10x + 22 = 13x as (x + c)² = d or (x - c)² = d, we need to complete the square on the left side of the equation.
Step 1: Move the constant term (22) to the right side of the equation:
x² + 10x = 13x - 22
Step 2: Move all terms involving x to the left side:
x² + 10x - 13x = -22
x² - 3x = -22
Step 3: Take half of the coefficient of x (-3) and square it.
To both sides of the equation, add the following value:
x² - 3x + (-3/2)² = -22 + (-3/2)²
Simplifying:
x² - 3x + 9/4 = -22 + 9/4
Step 4: Make the right side of the equation simpler:
-22 + 9/4 = -88/4 + 9/4 = -79/4
Step 5: The left side of the equation should now be written as a perfect square trinomial:
(x - 3/2)² = -79/4
Therefore, the rewritten equation, after completing the square, is
(x - 3/2)² = -79/4.

Four years ago, Sam invested in Grath Oil. She bought three of its $1,000 par value bonds at a market price of 93.938 and with an annual coupon rate of 6.5%. She also bought 450 shares of Grath Oil stock at $44.11, which has paid an annual dividend of $3.10 for each of the last ten years. Today, Grath Oil bonds have a market rate of 98.866 and Grath Oil stock sells for $45.55 per share. Use the scenario above to consider which statement best describes the relative risk between investing in stocks and bonds.
Answers
Answer:
C. The market price of the bonds is more stable than the price of the company's stock.
Step-by-step explanation:
In the context, Sam bought some bonds at the market price from Grath Oil and also invested in buying corporate shares which paid a dividend of $3.10 for each share annually for a period of ten years.
At present the market value of the bonds of Grath Oil is more. The market price of the bond is the amount of the money to be paid in an open market to buy a bond.
So the bond's market price is much more stable than the price of the company's stock. It is riskier to invest in company stocks.
