We can find the domain and range of the function without the help of graphing calculator by the following steps mentioned below.
What are domain and range?The domain of a function is the set of values that we are allowed to enter into our function.
This set consists of the x values for a function like f. (x).
The set of values that a function can accept as input is known as its range.
The function outputs this list of values once we enter an x value.
The domain of a function refers to the set of input values.
These numbers, which stand in for the independent variable, are corresponding to the x-axis value.
The range of a function refers to the set of output values.
These values, which indicate the dependent variable, are corresponding to the y-axis value.
Find a function's domain and range without graphing as follows:
(A) Place y = f(x)
(B) In terms of y, solve the equation y = f(x) for x. Let x = g (y)
(C) Discover the values of y and its domain of f for which the values of x, as determined by x = g(y), are real.
(D) The range of the supplied function is the collection of y values produced in step 3.
Therefore, we can find the domain and range of the function without the help of graphing calculator by the following steps mentioned above.

Use the information below to respond to numbers 5,6,7 and 8.
Celeste was selling meal tickets for the holiday program at her school. The cost of a dinner ticket is
$10. She is also selling dessert tickets for $6. She lost track of how many of each ticket she sold;
however, she remembered that she was given 100 tickets and she collected $900.
The system of equations shown can be used to represent this situation:
S x + y = 100
(10x + 6y=900
5. What does the variable x represent in the system of equations? *
1 point
O A. The number of dinner tickets sold.
O B. The number of dessert tickets sold.
O C. The number of dollars collected for dinner tickets.
D. The number of dollars collected for dessert tickets.
O Other:
X is next to the number 10, so x would be the number of dinner tickets sold.
Rewrite x + y = 100 to x = 100-y
Now replace that in the 2nd equation:
10(100-y) + 6y = 900
Simplify:
1000 -10y + 6y = 900
Combine like terms:
1000 -4y = 900
Subtract 1000 from both sides
-4y = -100
Divide both sides by-4
Y = 25
Replace y in the first equation and solve for x
X + 25 = 100
X = 75
A) 75 dinner tickets were sold
B) 25 dessert tickets were sold
C) 75 x 10 = $750
D) 25 x 6 = $150

Answer: 3x+5, (3x+5)*3 and 5x+4x+15
Step-by-step explanation:
Answer: I think the first one is 3x+5 since it’s a triangle, just divide it by 3 for one side.
5- 3x+5(3) and (6x+10) +(3x+5)
6- they’re equivalent because if you multiply each value for the first equation by 3, you get the original equation, the second is equal at because 6x+10 is equal to 2 sides while 3x+5 is still equal to one, so adding thos together would still give you the original equation, I’m sorry if this is wrong.

If the length of an arc of measure 55 degrees is 3.87 inches find the circumference of the circle
Answer:
25.33 is the circumference of the circle
Step-by-step explanation:
Here, given the measure of the arc, we want to get the circumference of the circle
mathematically, the length of an arc can be calculated using the formula;
theta/360 * 2 * pi* r
where 2 * pi * r = circumference of the circle
theta is the angle subtended at the center which is 55 degrees in this case
Thus, we have ;
55/360 * 2 * pi * r = 3.87
2 * pi * r = (3.87 * 360)/55
2 * pi * r = 25.33 inches

Answer:
113.04 ft³ is correct
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius and h the height )
There are 2 cones to be summed one with h = 7 , the other with h = 5
Thus
V = [tex]\frac{1}{3}[/tex] π × 3² × 7 + [tex]\frac{1}{3}[/tex]π × 3² × 5
= [tex]\frac{1}{3}[/tex] × 3.14 × 9 (7 + 5)
= 3.14 × 3 × 12

Which of the following describes the function of the nervous system?
A. to regulate internal temperature
B. to carry blood through the body
C. to rid the body of cellular waste
D. to respond to external stimuli
The best description of the function of the nervous system among all the options is to respond to external stimuli.
Your nervous system is your body’s command center. Originating from your brain, it controls your motions, studies, and instinctive reactions to the humankind around you. It too controls distinct body systems and processes, similar to digestion, breathing, and sexual growth( puberty). conditions, accidents, poisons, and the natural aging course can compromise your nervous system.
Thus, option D is correct in that the nervous system is responsible to respond to external stimuli.

Ms. Ruiz has a piece of fabric that is 3 3/4 yards long. She waves to cut it into 12 equal pieces. How many yards will each piece of fabric be
Answer:
the number of yards be 0.3125
Step-by-step explanation:
The computation of the number of yards will each piece of fabric be is shown below:
Given that
There is [tex]3 \frac{3}{4}[/tex] yards long i.e. 15 ÷ 4
And, it should be cut into 12 equal pieces
So, the number of yards will each piece of fabric be is
= 15 ÷ 4 ÷ 12 ÷ 1
= 15 ÷ 48
= 0.3125
Hence, the number of yards be 0.3125
Answer:
5/16
Step-by-step explanation:
3 3/4= 13/4
13/4 ÷ 12= 0.3125

A rectangular prism has a base area 56 ft.² and a volume of 840 ft.³ the length of the base is longer than the width if the sum of the length and the width of the base is equal to the height of the pyramid what is the length of the base in feet
Answer:
The length of the base in feet is 8 ft.
Step-by-step explanation:
The volume V of the rectangular prism is given by
V = l × w × h
But Area, A = l × w
∴ V = A × h
Where A is the base area and h is the height
From the question
A = 56 ft.² and V = 840 ft.³
∴ 840 ft.³ = 56 ft.² × h
840 ft.³ / 56 ft.² = h
15 ft. = h
∴ h = 15 ft.
Hence, the height of the rectangular prism is 15 ft.
Also, from the question
the sum of the length and the width of the base is equal to the height
i.e l + w = h
where l is the length of the base and w is the width of the base
Then, l + w = 15 ------ (1)
Also, A = l × w
Then, 56 = l × w ------- (2)
From equation (1)
l + w = 15
Then, w = 15 - l ------- (3)
Substitute this into equation (2)
56 = l × w
56 = l × (15-l)
56 = 15l - l²
Then,
l²- 15l + 56 = 0
l² -8l -7l + 56 = 0
l(l - 8) -7(l - 8) = 0
(l - 7)(l - 8) = 0
l - 7 = 0 OR l - 8 = 0
∴ l = 7 OR l = 8
Substitute the values of l into equation (3)
w = 15 - l
when l = 7
w = 15 - 7
w = 8
and when l = 8
w = 15 - 8
w = 7
From the question, the length of the base is longer than the width
∴ l = 8 and w = 7
Hence, the length of the base in feet is 8 ft.
