The nonlinear- function which represents b(9)=4 is given by b(x)=72/x - 4 .
In mathematics and physics, a nonlinear system is one in which the change in the output is not proportional to the change in the input. Engineers, biologists, physicists, mathematicians, and many other scientists are interested in nonlinear problems since the majority of systems are inherently nonlinear.
Nonlinear function graphs don't resemble lines at all. It contains the formula f(x) = ax + b. Its equation can take any form, with the exception of f(x) = ax + b. The slope of the curve is the same between any two points. The point pairs on the graph do not all have equal slopes.
Of all the given options: the only equations which imply that b(9)=4 are :
i) b(x)=72/x - 4 and (iv) b(x)=4
Of this two options only the first option is non-linear.

Describe the transformation from the graph off to the graph of g. PLEASE HELP!
Answer:

Step-by-step explanation:
You are given graphs of f(x) and g(x) and want to know the transformation that gives g(x) from f(x).
Transformations of graphsThe sorts of transformations of graphs that we study are translation, scaling (horizontally or vertically), and reflection about an axis.
Here, both graphs have the same shape, but one is in a different place than the other. The applicable transformation is one of translation.
TranslationThe vertex of f(x) is at (0, -1). The vertex of g(x) is at (0, 2). We note the x-value has not changed, but the y-value has had 3 added to it. (-1 +3 = 2)

Julian saved between $30 and $52
over the summer. His friend Daniela
saved twice as much. Let n represent
the amount of money Daniela saved.
What is the compound inequality?
The compound inequality is 60 < n < 104.
Let 'x' denote the amount of money saved by Julian.
Then x is between $30 and $52.
I.e., x>30 and x<52.
This can be written as a single inequality by combining the both.
i.e., 30 < x < 52
His friend Daniela saved twice as much as Julian.
Let 'n' denotes the amount of money Daniela saved.
Then n = 2x
We need to write the compound inequality for the money saved by Daniela.
As Daniela saved twice as much as Julian, it will be between 2 x 30 = $60 and 2 x 52 = $104
So the compound inequality is 60 < n < 104.

What is 48 = 3x - 15
Answer: x=21
Step-by-step explanation:
Two factory plants are making TV panels. Yesterday, Plant A produced 10,000 panels. Three percent of the panels from Plant A and 10% of the panels from Plant B were defective. How many panels did Plant B produce, if the overall percentage of defective panels from the two plants was 5%
If the overall percentage of the defective panels from the two plants is 5% then plant B produced 4000 panels in total.
This question can be solved by formulating the problem into the form of a linear equation having two variables. Linear equation in two variables can be represented in the form of ax+by+c=0 where a, b and c are real numbers and x, y are variables or the coefficients, and a, b ≠ 0.
Let the production from plant A be x, and according to the question x=10000.
Also, let the production from plant B be y.
Now, as 3% of products are found defective from plant A and 10% of products are found defective from plant B and overall defective products is 5%.
Thus, 0.03x+0.1y=0.05(x+y)
As x=10000 then
0.03×10000+0.1y=0.05(10000+y)
300+0.1y=500+0.05y
0.05y=200
=>y=4000
Thus, the total number of panels produced by plant B is equal to 4000.

4. A rocking horse has a weight limit of 60 pounds.
a. What percentage of the weight limit is 33 pounds?
b. What percentage of the weight limit is 114 pounds?
c. What weight is 95% of the limit?
Show your work
a. 55% of the maximum weight is 33 pounds.
b. 114 pounds is 190% of the weight limit.
c. 57 pounds is 95% of the maximum.
Answer to Part a:
Let c be the weight limit percentage for 33 pounds.
Then we have (60 x c)/100 = 33 pounds
This implies 3c/5 = 33
This means that 3c = 33 x 5 = 165.
This means that c = 165 / 3 = 55.
Therefore 55% of the weight limit is 33 pounds.
Answer to Part b:
Let d be the weight limit percentage for 114 pounds.
Then we have (60 x d)/100 = 114 pounds
This implies 3d/5 = 114
This means that 3d = 114 x 5 = 570.
This means that d = 570 / 3 = 190.
Therefore 190% of the weight limit is 114 pounds.
Answer to Part c:
95% of the weight limit is
= 95 x 60 /100
= 95 x 3/5
= 19 x 3
= 57
Therefore, 95% of the weight limit is 57 pounds.

Keilantra has $660 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $488.20.
She buys 2 bicycle reflectors for $11.17 each and a pair of bike gloves for $19.05.
She plans to spend some or all of the money she has left to buy new biking outfits for $37.26 each.
Write and solve an inequality which can be used to determine xx, the number of outfits Keilantra can purchase while staying within her budget.
The number of outfits she can buy is 3.
How many outfits can she buy?The The first step is to determine the total cost of all the items already bought.
Total cost = cost of new bicycle + (cost of one reflector x number of reflectors) + cost of the gloves
$488.20 + (2 x $11.17) + 19.05
$488.20 + 19.05 + $22.34 = $529.59
Now, determine the amount that is left to buy the outfits :
$660 - $529.59 = $130.41
Here are inequality signs and what they mean:

The area of the walkway and garden is represented by the expression
2x2 + 12x + 16. Write an expression in factored form that represents
the area of the walkway. Then find the area of the walkway if x is
3 meters. (Hint: Subtract the expression that represents the area of the
garden from the expression that represents the area of both before
factoring.)
The factorized form of the quadratic is 2*(x + 2)*(x + 4), and when x = 3m, the walkway area is 52 square meters.
How to factorize the area equation?
Here we know that the area is given by the expression:
2x^2 + 12x + 16
To factorize this, we need to find the roots of the quadratic equation, these are the solutions of:
2*x^2 + 12x + 16 = 0
The solutions are given by:
x = (-12 ± √(12^2 - 4*2*16))/(2*2)
x = (-12 ± 4)/4
The two solutions are:
x = (-12 + 4)/4 = -2
x = (-12 - 4)/4 = -4
Then the factored form is:
y = 2x^2 + 12x + 16 = 2*(x^2 + 6x + 8) = 2*(x + 2)*(x + 4)
Now we want to get the area if the walkway if x = 3, the total area of the walkway and the garden will be:
y = 2*(3 + 2)*(3 + 4) = 70
And the garden measures x by 2x, then if x = 3, the area of the garden is:
a = x*2x = 3*(2*3) = 18
Then the area of the walkway alone is:
70 - 18 = 52
The area of the walkway is 52 square meters.
