Answer:
Step-by-step explanation:
For a given function f(x), we define the domain as the set of the possible inputs of the function and the range as the set of the outputs of the function.
We will see that both domain and range are the set of all real numbers.
D = (-∞, ∞)
R = (-∞, ∞)
Here we have the function:
The first thing we need to do is find the domain.
We start by assuming that the domain is the set of all real numbers and then we try to find some given values of x that cause some undefined operation, and then we remove these values of x from the domain.
Where this would be something like a zero in the denominator or something like that. We also could have specific restrictions to the domain that are applied in some specific cases (for example if x represents a length we should remove the negative values from the domain).
Here we can see that we do not have any indetermination, thus the domain is the set of all real numbers.
Now to study the range we need to see the general function, we can see that as x tends to negative infinity y will also tend to negative infinity, while when x tends to infinity y will also tend to infinity.
Then the range will also be the set of all real numbers.

To become a member of the book-of-the-month club there is a $40 sign-up fee and a $2 monthly fee. Write an equation in slope-intercept form that models this situation.
Answer:
y = 2x + 40
Step-by-step explanation:
slope-intercept formula: y = mx + b
x = number of months
y = total cost
slope is 2 and y-intercept is 40

Answer:
Step-by-step explanation:
B
Answer:
B
Step-by-step explanation:
128/2=64 mph
(the rate)
2 hr= 120 min
so.. 120-24= 96
and with the wind speed is r-c and without it is r+c because your going against the wind.

A farmer wants to plant peas and carrots on no more than 400 acres of his farm. If x represents the number of acres of peas and y represents the number of acres of carrots for solution (x, y), then which is a viable solution?
Group of answer choices
(−125, 500)
(250, 150)
(400, −10)
(1, 400)
Answer:
(250, 150)
Step-by-step explanation:
The acreage cannot be negative, so choices A and C are eliminated. The sum of acreages cannot exceed 400, so choice D is eliminated.
Choice B has the allotted acreages total exactly 400, which is within the farmer's limit.
(250, 150) is a viable solution

The measure of angle is 4. The measure of its reference angle is
and tan eis
Step-by-step explanation:
the reference angle is the smallest angle difference between the defining terminal arm of the angle and the x-axis. it is always positive.
if an angle is smaller than 90°, then it is is own reference angle.
7pi/4 is 1pi/4 (or simply pi/4) short of a full circle (2pi or 8pi/4).
therefore, if is easy to see that this pi/4 is the reference angle (45°).
tan(7pi/4) = -1, while tan(pi/4) = 1.
for every 45° angel in every quadrant the absolute values of sine and cosine are equal.
but in quadrant 1 both, sine and cosine, are positive, while in quadrant 4 sine is negative and cosine is positive.
and since tan = sine/cosine, this gives us the results above.

WHAT IS 10x+55 = 100
Answer:
[tex]x=\cfrac{9}{2}\: or\: x=4.5[/tex]
Step-by-step explanation:
[tex]10x+55 = 100[/tex]
[tex]10x+55-55=100-55[/tex]
[tex]10x=45[/tex]
[tex]\cfrac{10x}{10}=\cfrac{45}{10}[/tex]
[tex]x=\cfrac{9}{2}[/tex]
HOPE IT HELPS!
Subtract 55 from both sides.
10x=100-55
Simplify 100-55 to 45.10x=45
Divide both sides by 10.
[tex]x = \frac{45}{10} [/tex]
Simplify[tex]x = \frac{9}{2} [/tex]
