If my function rule is y=x + 3, what is the OUTPUT if the input is 4?
Answer:
7
Step-by-step explanation:
The output is 'y'. The input would be 'x'.
[tex]y=x+3\\\\y=4+3\\\\y=7[/tex]
The output should be 7.
Hope this helps.
The output for the function y=x + 3 at input x = 4 will be y = 7.
What is a function?The expression that established the relationship between the dependent variable and independent variable is referred to as a function. In the function as the value of the independent variable varies the value of the dependent variable also varies.
Given the function is y=x + 3. the value of the output at input x = 4 will be calculated as:-
y = x + 3
Put x = 4 in the function.
y = 4 + 3
y = 7
Therefore, the output for the function y=x + 3 at input x = 4 will be y = 7.

A field in the shape of a square has an area of 8,100 square feet. How can you determine the length of one side of the field?
To determine the length of one side use the formula for the area of square. As a square is equal on all four sides, finding one length results in any of the four. Solve using the formula and you receive your answer of 90.
A = s²
8100 ft² = s² (set up formula)
√8100 ft² = s² ( get s alone by squaring both sides)
90 ft = s (answer)
We can conclude that the side of the given square with an area of 8100ft² is 90ft.
What is a square?A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles. It can alternatively be explained as a rectangle with two neighboring sides that are of equal length. A square is a two-dimensional plane object in geometry that has four equal sides and four equal but 90-degree angles.So, the area of the square is 8100ft².
Formula: s²So, we know that: 8100 = s²Now, calculate for s as follows:
s² = 8100s = √8100s = 90ftTherefore, we can conclude that the side of the given square with an area of 8100ft² is 90ft.

working together Alberto and Amanda can paint a fence in 4.12 hours. had she done it alone it would have taken Amanda 10 hours. find how long it would take Alberto to do it alone. A) 6.75 B) 5.02 c) 7.54 D)7.01
Answer:
D) 7.01
Step-by-step explanation:
The rates of doing work, in terms of jobs per hour, will add when the two painters are working together. If A represents Alberto's time to do the job alone, we have ...
1/4.12 = 1/10 + 1/A
(Jobs per hour is the inverse of hours per job.)
A = 1/(1/4.12 -1/10) ≈ 7.0068 ≈ 7.01
It takes Alberto 7.01 hours to do the job alone.

Complete the table as you answer the questions. Be prepared to explain your reasoning.
segment time distance speed
Pittsburgh to Saint Louis 1 hour 550 miles
Saint Louis to Albuquerque 1 hour 42 minutes
Albuquerque to Phoenix 330 miles
Step-by-step explanation:
We can complete the table as :
segment time distance speed
Pittsburgh to Saint Louis 1 hour 550 miles 550 miles/hour
Saint Louis to Albuquerque 1 hour 42 minutes 93.5 miles 550 miles/hour
Albuquerque to Phoenix 3/5 hour 330 miles 550 miles/hour
Since it is given in the question that the plane is flying in a constant speed from one place top another place.
So, it is maintaining the same speed to cover different distances for different time.
Thus the constant of proportionality is 550.

slope-intercept form: y = mx + b
m = the slope and b = the y-intercept.
We know that the line passes through x-coordinate 1 and y-coordinate 1 and has a slope of 2
Let's plug our numbers into the slope-intercept form
1 = 2(1) + b
Simplify the right side
1 = 2 + b
Subtract 2 from both sides
-1 = b

401 km 101 m – 34 km 153 m
Given :
An expression D = 401 km 101 m – 34 km 153 m.
To Find :
Value of D.
Solution :
We know, 1 km = 1000 m.
So, 401 km 101 m =( 401000 + 101 ) m = 401101 m.
Also, 34 km 153 m = ( 34000 + 153 ) m = 34153 m.
Now, D is given by :
D = 401101 - 34153 m
D = 366948 m
Now, D = 366948 m = 366 km 948 m.
Therefore, the difference is 366 km 948 m.
Hence, this is the required solution.

Joyce’s teacher asks her to write the sequence formed by the number of red squares in each picture for the first five pictures. What sequence should Joyce write?
Answer:
Joyce should write [tex]1,8,64,512,4096[/tex]
Step-by-step explanation:
Let's analyze the procedure of how the pictures are formed.
Her teacher said the images were created by taking a red square, dividing it into 9 smaller squares, and removing the center square.
For the first two images we can see and count that there is 1 red square in the first picture and 8 red squares in the second picture.
For the third image, there are 8 squares formed by 8 red squares each one.
The number of red squares is 8 x 8 = 64
We can write the sequence as
1 , 8 , 64 ⇒ 1 , 8 , [tex]8^{2}[/tex]
For the fourth picture we can do the same reasoning and figure out that there are 8 x 8 x 8 = 512 red squares in the fourth image.
The sequence so far is
1 , 8 , 64 , 512 ⇒ 1 , 8 , [tex]8^{2}[/tex] , [tex]8^{3}[/tex]
We can generalize the sequence and write that the sequence is :
[tex]8^{n}[/tex] with [tex]n[/tex] ∈ IN ⇒ The first five numbers will be
[tex]8^{0},8^{1},8^{2},8^{3},8^{4}[/tex] = [tex]1,8,64,512,4096[/tex]
