the domain is:
the range is:
Answers
Domain = {-3, -2, 0, 2, 4}
Range = {-4, 0, 2, 3, 5}
The domain is the set of all possible x values, so we just list all the unique x coordinates of each point. The y coordinates of each point is listed to form the range. Ignore any duplicates.

Write a linear function f with f(-4) = 2 and f(6) =-3
Answers
Answer:
f(x) = - [tex]\frac{1}{2}[/tex] x
Step-by-step explanation:
The standard form for a linear function is
f(x) = ax + b
Using the given values f(- 4) = 2 and f(6) = 3 , then
- 4a + b = 2 → (1)
6a + b = - 3 → (2)
Subtract (2) from (1) term by term to eliminate b
- 10a = 5 ( divide both sides by - 10 )
a = - [tex]\frac{1}{2}[/tex]
Substitute a = - [tex]\frac{1}{2}[/tex] into either of the 2 equations and solve for b
Substituting into (1)
2 + b = 2 ( subtract 2 from both sides )
b = 0
Thus the linear function is
f(x) = - [tex]\frac{1}{2}[/tex] x
The linear function is f(x) = -0.5x
For f(-4) = 2
x₁ = -4, y₁ = 2
For f(6) = -3
x₂ = 6, y₂ = -3
The slope(m) is found using the formula
m = (y₂ - y₁)/(x₂ - x₁)
m = (-3-2)/(6-(-4))
m = -5/10
m = -0.5
Substitute m = -0.5, x₁= -4, and y₁ = 2 into the equation below:
y - y₁ = m(x - x₁)
y - 2 = -0.5(x - (-4))
y - 2 = -0.5(x + 4)
y - 2 = -0.5x - 2
y = -0.5x - 2 + 2
y = -0.5x
Therefore, the linear function is f(x) = -0.5x

Answer:
k=45
Step-by-step explanation:
Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that [tex]45+2k+k=180[/tex]. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have [tex]45+3k=180[/tex]. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides [tex]45-45+3k=180 -45 \\3k=135[/tex] as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.

Kailey is correct: 89.12 times 10 Superscript 5 equals 8,912,000.
Kailey is not correct: the exponent of ten should be negative.
Kailey is correct: it is written as a decimal number multiplied by a power of ten.
Kailey is not correct: 89.12 times 10 Superscript 5 is not written in scientific notation.
Answers
Answer:
kailey is not correct 89.12 times 10 superscript 5 is not written in scientific notation
Step-by-step explanation:
8.912 times 10 superscript 5 is written is scientific notation
The true statement about Kailey's expression is (a) Kailey is not correct: 89.12 * 10 ^5 is not written in scientific notation.
How to determine the true statement?From the question, Kailey's expression can be represented as:
8,912,000 = 89.12 * 10^5 in scientific notation
To check if Kailey's expression is correct, we count the number of zeros in the number up to 8.9
The number of zero is 6.
So, the scientific notation of the number is
8,912,000 = 8.912 * 10^6
This means that Kailey's expression is not correct
Hence, the true statement is (d)

6.4 x 103 km
6.4 x 105 km
Answers
Answer:
[tex] 6.4 * 10^{3} km[/tex]
Step-by-step explanation:
Scientific notation can be defined as a way of expressing and writing a very small or large real number in decimal form. Generally, to use the scientific notation, we will multiply the real number by a power of 10.
Given that the length of Amazon River is 6,400 kilometers.
[tex] \frac{6400}{1000} = 6.4[/tex]
[tex] 1000 = 10^{3}[/tex]
Therefore,
6, 400 kilometers = 6.4 × 10³ kilometers.
help please i really need it

Problem 1
Answer: x = 9
----------
Explanation:
For now focus on triangle DEF. We need to find the missing angle D.
D+E+F = 180
D+71+42 = 180
D+113 = 180
D = 180-113
D = 67
In order for DE to be parallel to GH, the alternate interior angles EDF and GHF must be congruent
Let's see what happens when we force them to be equal
angle EDF = angle GHF
67 = 5x+22
67-22 = 5x
45 = 5x
5x = 45
x = 45/5
x = 9

Size of television is a continuous variable as the inches of televisions aren't finite and may not necessarily be whole numbers.
Screen type is a Qualitative variable also called categorical as it places different Television sets into distinct category based on the nature of the screen material.
Number of channela is discrete as it defines a finite number stations available. Available stations will always be whole numbers without decimals.
