Answer:

3

Step-by-step explanation:

First, we need to understand what the problem is asking for.

The range of a function is the set of the y-coordinates of all the points of the function.

The domain of a function is the set of the x-coordinates of all the points of the function.

"A range value" means the same as "the y-coordinate of one point."

This problem is telling you that the y-coordinate of a point of function f(x) =  -2x + 6 is 0. Then it asks what its domain value is. It is asking you what is the x-coordinate of the point that has 0 as its y-coordinate.

Simply put, for function f(x) = -2x + 6, when y = 0, what is x?

f(x) = −2x + 6

-2x + 6 = -

-2x = -6

x = 3

Answer: 3

The points (6, -3) and (7, -10) fall on a particular line. What is its equation in point-slope form? Use one of the specified po
kumpel [21]

Answer:

Step-by-step explanation:

Given the coordinate points (6, -3) and (7, -10), we are to find the equation of a line passing through this two points;

The standard equation of a line is y = mx+c

m is the slope

c is the intercept

Get the slope;

m = Δy/Δx = y2-y1/x2-x1

m = -10-(-3)/7-6

m = -10+3/1

m = -7

Get the intercept;

Substitute the point (6, -3) and m = -7 into the expression y = mx+c

-3 = -7(6)+c

-3 = -42 + c

c = -3 + 42

c = 39

Get the required equation by substituting m = -7 and c= 39 into the equation y = mx+c

y = -7x + 39

Hence the required equation is y = -7x + 39

This is urgent I need help!

Answer:

Step-by-step explanation:

1. Write an expression to show how to calculate the number of buses needed. Make sure to include parenthesis to show what should be done first since order of operations is important.

(9*25)+4+(2*4)=237 (total number of people going to the museum

Each bus,excluding the driver,holds 44 people

237/44 = 5.3863636363.......

2. How many buses will be needed?

 6 buses are needed

3. Why must the answer to the problem be a whole number?

Buses cannot be divided in fractions It should be or 5 buse or 6

But 5 buses are not enough

4. Why shouldn't you round the answer the usual way?

Even when rounded it is still a decimal and buses need to be counted by whole number

5. Can your answer be classified as a rational number? Explain why or why not.

6 is a rational number (whole number)

5.38636363.......is rational ( repeating decimal

I also got this one wrong as well can someone tell me what I'm doing wrong so I can change it
Angelina_Jolie [31]
The answer is:  [D]:  "Subtract 5 from 10" .
____________________________________
Explanation:
____________________________________
Use the correct order of operations, according to the mnemonic: 
         "PE MD AS".

The "P" stands for "parentheses", which takes top (first priority); and there are values in parentheses in this expression—specifically, the "(10 - 5)" .  So the first step is to "subtract 5 from 10" —which is:  "Answer choice: [D]".
    Your error was starting at the beginning of the problem; and not using the "order of operations".
