Suppose a stage for the Lunar New Year festival has a length of 24 feet and a width of 4x + 4 feet. If the area of the stage is 384 square feet, what is the value of x?
Answers
Answer:
The value of x is 3
Step-by-step explanation:
The stage is rectangular in shape.
The formula for area of a rectangle is:
Length × Width
Length = 24 feet
Width = 4x + 4 feet
Hence:
384 = (4x + 4) × (24)
384 = 96x + 96
Collect like terms
384 - 96 = 96x
288 = 96x
x = 288/96
x = 3
The value of x is 3
Stan evaluated a function with a value and got 3 as the result. He wrote the entire process as a sentence: The function , when evaluated with , gives the value 3.
Answers
The function f(x) = x^2-1 when evaluated with 2, gives the value 3.
What is a function?A function can then be defined as a set of ordered pairs. Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
For the given situation,
Stan evaluated a function with a value and got 3 as the result.
For this statement, we can frame many functions with different inputs.
Let us consider the function,
(1) [tex]f(x)=2x-3[/tex]
Now substitute x = 3,
⇒ [tex]f(3)=2(3)-3[/tex]
⇒ [tex]f(3)=6-3\\[/tex]
⇒ [tex]f(3)=3[/tex]
(2) [tex]f(x)=x^{2} -1\\[/tex]
Now put x = 2,
⇒ [tex]f(2)=2^{2}-1[/tex]
⇒ [tex]f(2)=4-1[/tex]
⇒ [tex]f(2)=3[/tex]
Similarly we can make many functions that has the value 3 as the result.
Hence we can conclude that the function f(x) = x^2-1 when evaluated with 2, gives the value 3.

al made a treehouse last summer. He started by making a model. the model included a window with height 1/3 inch. and width 1/6 inch. the actual tree house window had height of 1/2 yd. and width 1/4 yd. al incorrectly said that the ratio of the height of the window in the model to the height of the window in the tree house was 3/2. what was the correct ratio?
What’s is Al’s likely error?
A- He reversed the order of the terms in the ratio
B-he found the ratio of the height to width for one window instead of the ratio of heights
C- He did not covert one of the units before finding the ratio
D-He found the ratio of the widths instead of the ratio of the heights.

It costs $4.25 per game at the bowling alley.
plus $1.90 to rent shoes. If Wayne has $20.
how many games can he bowl?
Answers
Answer:
Wanye can only bowl 4 times.
Step-by-step explanation:
the expression for this equation is
20 = 4.25x + 1.90
subtract 1.90 from both sides
18.10 = 4.25x
See how many times 4.25 can go into 18.10
1.) 18.10 - 4.25 = 13.85
2.) 13.85 - 4.25 = 9.60
3.) 9.60 - 4.25 = 5.35
4.) 5.35 - 4.25 = 1.1
1.1 < 4.25 so you can't subtract it
the answer is 4 times

Row 1: No, No, No
Row 2: Yes, Yes, Yes
===============================
Explanation:
Use the vertical line test. If it is at all possible to draw a single vertical line through more than one point on the relation curve, then the relation is not a function. This is because a function is only possible when any x input leads to exactly one y output.
So that's why graphs 1,2,3 are not functions, while graphs 4,5,6 are functions.
What is the solution to this system of linear equations?
x + y = 4
x − y = 6
Answers
Answer:
x=5 , y= -1
Step-by-step explanation:
You can see that one of the y's is negative while the other is positive, so you can add them together.
Now, negative 1 + positive 1 = 0, so the y's cancel out leaving only the x's.
Remember you can't add one part without adding the other so x+x = 2x, and 4+6=10. This makes the final equation 2x=10.
You can simplify that into x=5. This gives you the answer for x
Then substitute x=5 into any of the two equations (doesn't matter) I'll use the first one. So if you substitute it you get 5+y=4.
Simplified, y= -1
Therefore, x= 5 and y=-1
