Suppose that a good has an income elasticity of demand of -2. 0. This means that the good is
The good has an income elasticity of demand of -2. 0. This means that the good is inferior goods.
What are the characteristics of inferior goods?An inferior good occurs when an increase in income causes a fall in demand.
An inferior good has a negative income elasticity of demand. (YED) Inferior goods are characterized by low quality – and are goods with better alternatives.
Suppose that good has an income elasticity of demand of -2. 0. This means that the good is inferior goods.
An inferior good is one whose demand drops when people's incomes rise. When incomes are low or the economy contracts, inferior goods become a more affordable substitute for more expensive goods.
Inferior goods are the opposite of normal goods, whose demand increases even when incomes increase.
Hence, the good has an income elasticity of demand of -2. 0. This means that the good is inferior goods.

find the value using x
Work Shown:
9/12 = (x+4)/(2x)
9(2x) = 12(x+4)
18x = 12x+48
18x-12x = 48
6x = 48
x = 48/6
x = 8
The diameter of a circle is 26 millimeters. What is the circle's circumference?
Step-by-step explanation: the answer for this question should be 81.64 because to find the circumference you need to know the circumference formulas which is C=TT times d or C= 2 times TT times r.
C= 3.14 times 26 C= 2 times 3.14 times 13
C= 81.64
C= 81.64
so the answer is 81.64 for the circle's circumference so hopefully that is the correct answer and have a great day

direction. The number b varies directly with the number a. For example b = 2 when a = -2
-2. Which equation
=
4
represents this direct variation between a and b?
b = -a
-b = -a
ОООС
b-a= 0
b(-a) = 0
Answer:
b = - a
Step-by-step explanation:
given b varies directly with a then the equation relating them is
b = ka ← k is the constant of variation
to find k use the condition b = 2 when a = - 2 , then
2 = - 2k ( divide both sides by - 2 )
- 1 = k
then
b = - a ← equation of variation

D. Lymphocytes
Answer:
Answer is D.
Lymphocytes.
Explanation.
How Does the Immune System Work? When the body senses foreign substances (called antigens), the immune system works to recognize the antigens and get rid of them. B lymphocytes are triggered to make antibodies (also called immunoglobulins). These proteins lock onto specific antigens.

Answer: 1/32
Step-by-step explanation:
1st step: 1/4 divided by 8, which is 1/4 divided by 8/1
Then for the 2nd step, you have to find the reciprocal of the 2nd fraction, so you just reverse it
2nd step: 1/4 X 1/8
3rd step. 1X1/4X8 = 1/32
You can also think of it like this. He started with 4 pieces. Each piece was then divided into 8 parts. So 8X4=32 is the total number of pieces. He's only eating 1 of those, so he's only eating 1/32.
Answer:
1/32
Step-by-step explanation:
[tex]\displaystyle \frac{\frac{1}{4}}{8}=\frac{1}{4*8}=\frac{1}{32}[/tex]
So, Jordan is thinking about eating 1/32nd of the pancake

Answer:
7.3 cm
Explanation:
Given a right angle triangle, In order to find the third side: Use Pythagoras Theorem: a² + b² = c²
Insert values:
x² + 8.9² = 11.5²
x² + 79.21 = 132.25
x² = 132.25 - 79.21 (subtract)
x² = 53.04
x = √53.04 (square root)
x = 7.28285 ≈ 7.3 (rounded to 1 decimal place)
11.5 cm
8.9 cm
to find:the unknown value "x"
solution:we'll have to use pythagoras theorem.
unknown value is x
[tex] {c}^{2} = {b}^{2} - {a}^{2} [/tex]
[tex] {x}^{2} = {11.5 }^{2} - {8.9}^{2} [/tex]
[tex] {x}^{2} = 53.04[/tex]
[tex]x = \sqrt{53.04} [/tex]

Given the relation: {(1,2),(2,3),(-1,3),(2,5)}
Determine what two points cause the relation to not be a function? Explain why these points cause the relation to not be a function.
Answer: (2,3) and (2,5) cause the relation to not be a function
Explanation:
The input x = 2 leads to y = 3 and y = 5 at the same time for both points. A function is where any input x leads to exactly one y output only. So we'd need to get rid of one of those mentioned points to be able to have a function.
If you graphed the points on the same xy grid, then you'd see (2,3) and (2,5) vertically aligned. These two points cause the vertical line test to fail. This will give a visual indication we do not have a function.
Put another way, if x repeats itself then we don't have a function. The y value is allowed to repeat. So we could have something like (1,2) and (5,2) be part of a function.
