What is the domain of the function y = √2x − 6
step by step pls

Answers

Answer 1
answer: x is greater than or equal to 3. this is because if x is less than 3, for example, -1, the number under the radical would be -2-6, or -8. you cannot have a square root of a negative, hope this helped!

the image below, what is true about angles 1, 2, and 3?

A. 3 = 37
B. 1 = 37
C. 2 = 37

Answers

Answer:

C. 2 = 37

Step-by-step explanation:

<2 and 37 are vertical angles and vertical angles are equal

Angle 1 and 37 form a straight line so they add to 180

<1 + 37 = 180

<1 = 180-37 = 143

Angle 3 and 37 form a straight line so they add to 180

<3 + 37 = 180

<3= 180-37 = 143

answer is C 2= 37 because the angle properties says that if it is an opposite angle it has the same angles..

Crayola Classic markers come in packages of eight. Crayola Tropical markers come in packages of ten. Sheldon wants the same number of Classic and Tropical markers. What is the fewest number of packages he could buy of each type of marker? Show proof of your answer.

Answers

Answer:

Crayola Classic: 5 Packs; Crayola Tropical: 4 Packs

Step-by-step explanation:

Keep multiplying by both until you get a number equal to eachother

1. 8 x 2 = 16,  10 x 2 = 20

2. 8 x 3 = 24, 10 x 3 = 30

You may notice that the numbers are getting farther apart. This is normal because the boxes are not equal and are getting multiplied further. That means that your answer will have different factors in both the equations.

3. 8 x 4 = 32, 10 x 4 = 40

4. 8 x 5 = 40

Both of those equations (in bold) have the same answer and he wanted the same crayons from both. So, the answer is:

10 x 4 = 40

8 x 5 = 40

(how much packs of each you need to get the same amount)

Hope this helps :)

The number without the variable (the letter x) is referred to as the y intercept. Therefore, it refers to the point along the y axis (up and down). For instance, in the first problem, the y intercept is -3. You would then go down 3 spaces and draw in the point.

The slope always has the x variable next to it. For instance, the slope of the first question is (positive) 2. To graph that, you would go up 2, and to the right one. Then you would repeat.

Which equation represents a linear function?
A. y= 1/2 x to the second power - 5
B. y= 1/2 x to the third power - 5
C. y= 1/2 x + 5
D. y=(1/2) to a power - 5

Answers

Answer:

C. y = 1/2x + 5

Step-by-step explanation:

For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.

For D. it doesn't even have x in it, so basically y equals a number.

C. is a linear equation, y = 1/2x + 5

The answer is C: y= 1/2 x +5

This is because any slope to a certain power would make it an exponential function.

C. y= 1/2 x + 5 is not to any power, making it linear

Take whatever you have written on the bottom of the x axis (like feet) and whatever you have on the y axis like (time) and put them together into a sentence. Something like - "after 90 minutes (time) the whatever u r talking about traveled 200 feet (distance.)" <--- THIS IS JUST AN EXAMPLE DO NOT USE THIS.

Answer:

m= [tex]\frac{1}{4} \\[/tex]

Step-by-step explanation:

Use the slope formula to get your answer. (m = y₂ - y₁ / x₂ - x₁ )

x₁ = 0

y₁ = 1

x₂ = 4

y₂ = 2

When you insert them into the formula, you get

m= [tex]\frac{2 - 1}{4 - 0}[/tex]

which equals [tex]\frac{1}{4}[/tex].

Please i need this turned in by 2:00 om so dont answer if you dont know Four fundamental factors affect the cost of money: (1) the return that borrowers expect to earn on their investments, (2) the preference of savers to spend their income in the current period rather than delay their consumption until some future period, (3) the risks associated with the investment, and (4) expected inflation. Consider the following statements that address these factors, and indicate which you think are true.Statement 1: The onset of 5% inflation means that your receipt of a $100 interest payment allows you to purchase only $95 worth of goods and services. Statement 2: For the average rational investor or saver, there is an indirect, or inverse, relationship between the amount of risk exhibited by a security and the risk premium that would be required by the investor or saver. Statement 3: On average and everything else held constant, rational savers and investors prefer to invest $1,500 to acquire an asset that will pay annual cash flows of $300 per year rather than an otherwise identical asset that will pay $500 per year. Statement 4: The actual relationship between the risk-free rate of return (r*) and the expected future inflation rate or inflation premium (IP) is actually multiplicative-that is, [(1 + rRF) x (1 + IP)]-1-but it is often simplified to reflect an additive relationship.The true statements are: a. 2 and 3 b. 2 and 4 c. 1 and 4 d. 1 and 3 True or false?
