Answer:
y = 0.35x
Step-by-step explanation:
Jane:
Cost of 3 postcards= $1.05
Cost of 1 post card = 1.05 ÷ 3
= $ 0.35
Rosi:
Cost of 5 postcards= $1.75
Cost of 1 post card = 1.75 ÷ 5
= $ 0.35
Tanya:
Cost of 8 postcards= $2.80
Cost of 1 post card = 2.80 ÷ 8
= $ 0.35
As unit rate is same, Cost and number of postcards are in proportion.
Cost of cards = 0.35 * number of cards
y = 0.35*x
y = 0.35x

Answer:
Parabola
Step-by-step explanation:
A parabola will be formed when a plane intersects the central axis at 50°
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
The angle between the generator and the central axis of a double-napped cone is 50° and a plane intersects the central axis at 50°
Ф = ∅
Where Ф is the angle between the vertical axis and plane and
∅ is the angle between the generator and central axis.
When both angles are the same the parabola is formed by the intersection of the plane.
Thus, a parabola will be formed when a plane intersects the central axis at 50°

Solve for x: 3x + 4 = 9x + 3
Answers
Answer:
x = 1/6
Step-by-step explanation:
Subtract 4 from both sides of the equation.
3x + 4 - 4 = 9x + 3 - 4
Simplify, subtract the numbers.
3x = 9x - 1
Subtract 9x from both sides of the equation.
3x - 9x = 9x - 1 - 9x
Simplify, combine like terms.
-6x = -1
Divide both sides of the equation by the same term.
-6x/-6 = -1/-6
Simplify, cancel terms that are in both the numerator and denominator, and divide the numbers.
x = 1/6
The solution to the given equation 3x + 4 = 9x + 3 is x = 1/6.
The equation is given as follows:
3x + 4 = 9x + 3
To solve the equation 3x + 4 = 9x + 3 for x, we need to isolate the variable x on one side of the equation.
Start by subtracting 3x from both sides of the equation to move all the terms involving x to one side:
3x - 3x + 4 = 9x - 3x + 3
4 = 6x + 3
Next, subtract 3 from both sides to isolate the term with 6x on the right side:
4 - 3 = 6x + 3 - 3
1 = 6x
Divide both sides of the equation by 6 to solve for x:
(1)/6 = (6x)/6
1/6 = x
Thus, the solution to the equation is x = 1/6.

The wording on this is not the best. It sounds like the 1 zero has even multiplicity (that's because of where the modifier is). On top of that it has an odd power. You could try this. y =x*(x^2+1)^2
The problem is not with the power. It gives x^5. The problem is with the multiplicity of the one place where it crosses. (X^2 + 1) does factor, but it gives a complex root. I'm not sure that's allowed. However, it is the best I can do.
A rectangular lot is 120 meters long and 85 meters wide.
Give the length and width of another rectangular lot that has the same perimeter but a smaller area.
Answers
The length and width of another rectangular lot that has the same perimeter but a smaller area will be 140 and 65m
How to illustrate the information?It should be noted that perimeter is calculated as:
Perimeter = 2(Length + Width)
Perimeter = 2(120 + 85)
Perimeter = 410m
Therefore, the length and width of another rectangular lot that has the same perimeter but a smaller area will be 140 and 65.
The area will be:
= 140m × 65m
= 9100m²
This is smaller than (120 × 85) = 10200m².

Answers
Answer:
x = 27/16
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
x + 5/9x = 2(3 - x)
Step 2: Solve for x
Distribute 2: x + 5/9x = 6 - 2xCombine like terms: 14/9x = 6 - 2xAdd 2x on both sides: 32/9x = 6Divide 32/9 on both sides: x = 27/16Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 27/16 + 5/9(27/16) = 2(3 - 27/16)Multiply: 27/16 + 15/16 = 2(3 - 27/16)Subtract: 27/16 + 15/16 = 2(21/16)Multiply: 27/16 + 15/16 = 21/8Add: 21/8 = 21/8Here we see that 21/8 does indeed equal 21/8.
∴ x = 27/16 is a solution to the equation.

The range of the function represented by the graph is 1 < y < 8
What is the domain of a function?The domain of the function is the set of input values of the graph
What is the range of a function?The range of a function is the set of output values of the graph.
How to determine the domain and the range?The graph represents the given parameters
On the graph, we have the following endpoints
Closed circle at (-13, 4)
Open circle at (11, 1)
Maximum = (4, 8)
The definition of the range implies that the range of a function is the set of y values of the graph.
Recall that
Closed circle at (-13, 4)
Open circle at (11, 1)
Maximum = (4, 8)
Remove the larger y value of the endpoints
Open circle at (11, 1)
Maximum = (4, 8)
Remove the x coordinates
So, we have
Open circle at (1)
Maximum = (8)
Combine the y values
1 < y < 8
Hence, the range of the function is 1 < y < 8
