The elasticity of expenditure is given by;e = δY/δX * X/Ywhere δY/δX is the slope of the demand curve and can be obtained by taking the derivative of the demand curve. X/Y is the expenditure share of X.In the given equation:
Y = 7.6182 + 0.08145X, we can rearrange to give X in terms of Y; X = (Y - 7.6182) / 0.08145Hence, expenditure share of X (X/Y) = (262.5 - 7.6182) / 29 = 8.9743.
Now we need to find δY/δX, by taking the derivative of the demand equation above, we get;δY/δX = 0.08145*Hence, the elasticity of expenditure is;e = δY/δX * X/Y = 0.08145*(262.5/29) = 0.731Conclusion:The value of elasticity of expenditure obtained above is less than one (0.731 < 1). This implies that the demand for X is inelastic. Hence, a 1% increase in the price of X will cause less than 1% decrease in the quantity demanded. Conversely, a 1% decrease in the price of X will cause less than 1% increase in the quantity demanded.
The elasticity of expenditure (E) is a metric used to measure the sensitivity of the quantity demanded of a good or service to a change in the price of that good or service. If E > 1, then the good or service is considered elastic. This means that a small change in price can cause a significant change in the quantity demanded of the good or service.
If E = 1, then the good or service is considered to have unit elasticity. This means that a change in price will cause a proportional change in the quantity demanded. If E < 1, then the good or service is considered inelastic. This means that a change in price will cause a relatively small change in the quantity demanded. In the given model above, the elasticity of expenditure was computed as 0.731. Since this value is less than one, it implies that the demand for the good is inelastic. A 1% increase in the price of the good will cause a less than 1% decrease in the quantity demanded. Conversely, a 1% decrease in the price of the good will cause less than a 1% increase in the quantity demanded.

Distributive Property 1
2(x+3)
What is the answer
Answer:
Step-by-step explanation:2x +6
Answer:
2x+6
Step-by-step explanation:
Definition - To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Other examples-
5(4x+5) -------> You would distribute(Multiply) 5 into 4x+5
5 times 4x is equal to 20
5 times 5 is equal to 25
The sign is addition
Thus, 20x+25

The scale of a map is 1:10,000,000. What is the real distance between two cities if the distance between them on map is 1.7 dm.
Answer:
1700 km
Step-by-step explanation:
Multiply the map scale by 1.7 dm:
1.7 dm : 17,000,000 dm
At this distance, a more useful unit is km, so we have ...
(17×10^6)(10^-1 m) = 1.7×10^6 m = 1700×10^3 m = 1700 km

Leanor pays a total of $16.50 for every 6 shirts she has dry-cleaned. Which graph models a
relationship with the same unit rate?
Answer:
Graph (F)
Step-by-step explanation:
Leanor pays a total of $16.50 for every 6 shirts she has dry cleaned.
Unit rate to dry clean the shirts will show the slope of the line plotted for price Vs number of shirts dry cleaned.
Unit rate = [tex]\frac{16.5}{6}[/tex] = $2.75 per shirt
≈ $2.8 per shirt
From the given graphs attached,
Slope of the line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Graph (F)
Slope = [tex]\frac{25}{9}=2.78[/tex]
≈ 2.8
Graph (G)
Slope = [tex]\frac{50}{3}=26.67[/tex]
Graph (H)
Slope = [tex]\frac{20}{2}=10[/tex]
Graph (J)
Slope = [tex]\frac{45}{2}[/tex] = 22.5
Therefore, graph (F) will be the answer.

Using Slopes of Parallel Lines Quick Check
Item 1
A quadrilateral ABCD has vertices A at (0,2), B at (2,6), C at (9,6), and D at (7,2). Are the opposite sides of this
quadrilateral parallel? (1 point)
Item 2
O Yes. AB is parallel to CD, but AD is not parallel to BC
Item 3
Item 4
O Yes. AB is parallel to CD and AD is parallel to BC
Item 5
O NO AD is parallel to BC but AB is not parallel to CD
O NO AB is parallel to CD, and AD is parallel to BC
Answer:
The answer is (B) ⇒ Yes. AB is parallel to CD and AD is parallel to BC
Step-by-step explanation:
There is an important fact about the parallel lines:
Parallel lines have equal slopesThe rule of the slope of a line is:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex], where [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are two points on the lineLet us use the fact and the rule to solve the question
∵ ABCD is a quadrilateral
∵ A = (0, 2) , B = (2, 6), C = (9, 6), D = (7, 2)
∵ The opposite sides are AB, CD and AD, BC
Find the slopes of the four sides to check the parallel sides
∵ [tex]m_{AB}=\frac{6-2}{2-0}=\frac{4}{2}=2[/tex]
∵ [tex]m_{CD}=\frac{2-6}{7-9}=\frac{-4}{-2}=2[/tex]
∵ The slope of AB = The slope of CD
∴ AB // CD
∵ [tex]m_{AD}=\frac{2-2}{7-0}=\frac{0}{7}=0[/tex]
∵ [tex]m_{BC}=\frac{6-6}{9-2}=\frac{0}{7}=0[/tex]
∵ The slope of AB = The slope of CD
∴ AD // BC
The correct answer is:
Yes. AB is parallel to CD and AD is parallel to BC ⇒ (B)
Graph the line y = kx +1 if it is known that the point M belongs to it: M(1,3)
Answer:
[tex]M(x,y) = (1,3)[/tex] belongs to the line [tex]y = 2\cdot x +1[/tex]. Please see attachment below to know the graph of the line.
Step-by-step explanation:
From Analytical Geometry we know that a line is represented by this formula:
[tex]y=k\cdot x + b[/tex]
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]k[/tex] - Slope, dimensionless.
[tex]b[/tex] - y-Intercept, dimensionless.
If we know that [tex]b = 1[/tex], [tex]x = 1[/tex] and [tex]y = 3[/tex], then we clear slope and solve the resulting expression:
[tex]k = \frac{y-b}{x}[/tex]
[tex]k = \frac{3-1}{1}[/tex]
[tex]k = 2[/tex]
Then, we conclude that point [tex]M(x,y) = (1,3)[/tex] belongs to the line [tex]y = 2\cdot x +1[/tex], whose graph is presented below.

A company's gross profit rate measures how well the company maximizes its profits in terms of cost and sales.
The gross profit rate,P , is calculated using the formula P= s-c/s, where s is the net sales and c is the cost of goods sold.
Which of the following equations correctly rearranges the formula to SOLVE FOR C, the cost of goods sold?
A)c=P
B)c=-P
C)c=Ps-s
D)c=-Ps+s
Answer:
D
Step-by-step explanation:
P = s-c/s
~Multiply s to both sides
Ps = -c + s
~Subtract s to both sides
Ps - s = -c
~Divide -1 to both sides
-ps + s = c

Find the measures of two supplementary angles if their measures are in the given ratio.
2:3
Answer:
The measures of the two angles are 72° and 108°
Step-by-step explanation:
Let us revise the meaning of supplementary angles.
The supplementary angles are the angles whose sum of measures
equal to 180°
∵ The ratio between the two supplementary angles is 2 : 3
∵ The sum of the supplementary angles is 180°
→ Let us use the ratio method to solve the question
⇒ ∠1 : ∠2 : ∠1 + ∠2
⇒ 2 : 3 : 5 (2 + 3)
⇒ ? : ? : 180
By using cross multiplication
∵ ∠1 = (2 × 180) ÷ 5
∴ ∠1 = 360 ÷ 5
∴ ∠1 = 72°
∵ ∠2 = (3 × 180) ÷ 5
∴ ∠2 = 540 ÷ 5
∴ ∠2 = 108°
∴ The measures of the two angles are 72° and 108°

Answer:
9) 25 is the hypotenuse so it should be replaced with c, not a or b.
10) 6.5 feet
Step-by-step explanation:
9) The pythagorean theorem is [tex]a^2+b^2=c^2[/tex].
The pythagorean theorem says that c MUST always be the hypotenuse length. The hypotenuse side can be identified because it is always on the opposite side of the right angle and the diagonal one (and of course the longest side).
a and b can be any other side except for c. What they did wrong was that they put the hypotenuse side as b.
Now to correct the error
[tex]a^2+b^2=c^2\\7^2+b^2=25^2\\49+b^2=625\\49+b^2-49=625-49\\b^2=576\\[/tex]
[tex]\sqrt{b^2}=\sqrt{576} \\b=24[/tex]
The missing side length is 24.
10) The question is asking for the c length (which is the hypotenuse). Use pythagorean theorem to solve for c.
[tex]a^2+b^2=c^2\\5.6^2+3.3^2=c^2\\42.25=c^2\\\sqrt{42.25}=\sqrt{c^2}\\6.5=c[/tex]

Find three consecutive even integers such that the sum of the smallest number and twice the middle number is 20 more than the largest number.
Answer:
10, 12, 14Step-by-step explanation:
Consecutive even integers increase by 2.
x ← an integer
2x ← an even integer (the smallest)
2x+2 ← next even integer consecutive to 2x (the middle one)
2x+2+2=2x+4 ← the last even integer consecutive to 2x+2 (the largest)
2(2x+2) ← twice the middle number
2x+2(2x+2) ← the sum of the smallest number and twice the middle
2x+4+20 ← 20 more than the largest number
2x + 2(2x + 2) = 2x + 4 + 20
2x + 4x + 4 = 2x + 24
-4 -4
6x = 2x + 20
-2x -2x
4x = 20
÷2 ÷2
2x = 10
2x+2 = 10+2 = 12
2x+4 = 10+4 = 14

Answer:
f(x) = x³ + x² - 22x - 40
Step-by-step explanation:
Given that x = a is a zero of f(x) then (x - a) is a factor
Here the zeros are x = - 4, x = - 2, x = 5 , then the factors are
(x + 4), (x + 2) and (x - 5)
The function is then the product of the factors, that is
f(x) = (x + 4)(x + 2)(x - 5) ← expand the first pair using FOIL
= (x² + 6x + 8)(x - 5) ← distribute
= x³ + 6x² + 8x - 5x² - 30x - 40 ← collect like terms
= x³ + x² - 22x - 40
