What is the linear equation with two variables ?
A linear equation with two variables is any equation that can be expressed in form ax + by + c = 0, where a, b, and c are all real values.
The given equation is a form of linear equation with two variables.
The equation is 16x + 28y = 112.
From graph it is clear that coordinates of Y are Y(1 , -1).
So , let's check for the value of x by putting the values of y in given expression.
i.e.,
The resulted equations will be :
16 x + 28 (1) = 112
or
16x + 28(-1) = 112
So ,
16 x + 28 = 112 --- -- -- ----- ----- ---- ---- ---- ---- ---- ---- ---- Equation 1
16x - 28 = 112 --- -- -- ----- ----- ---- ---- ---- ---- ---- ---- ---- Equation 2
The values of x will be :
x = 84 / 16 = 21 / 4
or
x = 140 / 16 = 35 / 4
The coordinates of X will be X([tex]\frac{21}{4}[/tex] , [tex]\frac{35}{4}[/tex] ).
Therefore , solving for the value of x using the graph we get the coordinates of X as X( [tex]\frac{21}{4}[/tex] , [tex]\frac{35}{4}[/tex] ).

Step-by-step explanation:
A chef had to fill up 4⁄6 of a container with mashed potatoes. He ended up using 3 2⁄4 pounds of mashed potatoes. How many pounds would he use if he had to fill up the entire container?
5.25 pounds of mashed potatoes is required to fill the container.
How Many Pounds to Fill the ContainerIn the question, we were told the container was 4/6 filled and the chef used 3 2/4 pounds which is equal to 14/4 pounds of mashed potatoes.
In doing this, we are calculating the volume of the container.
Let's equate this and find how many pounds will fill the container.
[tex]\frac{4}{6}fill = \frac{14}{4} pounds\\ 1 fill = x pounds[/tex]
Let's cross multiply both sides and solve for x.
[tex]\frac{4}{6}fill = \frac{14}{4} pounds\\1 = x pounds\\x = \frac{1 * \frac{14}{4} }{\frac{4}{6} }\\x = \frac{21}{4} = 5.25 pounds[/tex]

please give me explaination
The range of the exponential function f(x) is 1 / 32 ≤ f(x) ≤ 16.
How to find the range of an exponential function
Exponential functions are monotonous functions, that is, functions that are increasing or increasing but never both. Functions are defined by the following three features:
Domain - Set of input variables.Range - Set of output variables.Relation - Relations between domain and range.In this problem we find a function with an input variable (x) and an output variable (f(x)). Since exponential functions are monotonous functions we can determine the bounds of the range by the function evaluated at x = - 5 and x = 4. Thus:
f(- 5) = 2⁻⁵
f(- 5) = 1 / 2⁵
f(- 5) = 1 / 32
f(4) = 2⁴
f(4) = 16
The range of the function f(x) = 2ˣ for - 5 ≤ x ≤ 4 is 1 / 32 ≤ f(x) ≤ 16.

among all rectangles that have a perimeter of 48, find the dimensions of the one whose area is largest. write your answers as fractions reduced to lowest terms.
among all rectangles that have a perimeter of 48 Then the dimensions of the one whose area is largest is 12 by 12
The formula for calculating the perimeter of a rectangle is expressed as:
P = 2(L + W)
L is the length of the rectangle
W is the width
Given that the perimeter is 156, hence;
2(L + W) = 48
2L + 2W = 48
L + W = 24
W = 24 - L
The area of the rectangle is expressed as:
A = LW
A = L(24-L)
A = 24L - L^2
To get the dimensions of the one whose area is largest, dA/dL = 0
dA/dL = 24 - 2L
0 = 24 - 2L
2L = 24
L = 24/2
L = 12
Recall that 2(L+W) = 48
2(12 + W) = 48
12 + W = 24
W = 24 - 12
W = 12
Hence the dimensions of the one whose area is largest is 12 by 12

wht is the ending balance of R341000 at 4% for 3 years?
The ending balance for a amount of Rs. 341,000 with a interest rate of 4% for the time period of 3 years is Rs. 381920.
What is interest?
In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principal amount (the amount borrowed).
Information given in the question,
Principle amount = 341,000
Time period = 3 years
Interest rate is 4 % which can be written as 0.04 in decimals.
We can calculate the ending balance using this formula formula for simple interest:
[tex]S.I. = Principle \times Interest \times time[/tex]
Putting the values given in the question
S.I. = (341000)(0.04)(3)
S.I. = 40,920
Interest is 40,920.
The ending balance is the sum of Principle amount and Interest. So,
ending balance = 341000+40920
ending balance = 381920

If the area of the rectangular billboard covered by the ribbon was approximately 3360 square feet, and the width of the billboard was approximately 56 feet, the height of the billboard would be 71.25 feet.
What is area?The exact measurement that helps to express the size of a region on a plane or curved surface is thus called as area.
Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
In mathematical terminology, area can be defined as the total space that is taken up by a flat (2-D) surface or shape of a present object.
Here the area of the billboard = 3360 sq feet
Width of the billboard = 56 feet
We know that
area of the billboard = Height of the billboard x Width of the billboard
⇒ Height of the billboard = [Area of the billboard] / [Width of the billboard]
⇒ Height of the billboard= 3360/56

How long will it take for a $4000 investment to grow to $5780 at an annual rate of 4%, compounded quarterly? Assume that no withdrawals are made. Do not round any intermediate computations, and round your answer to the nearest hundredths.
The working equation when dealing with problems regarding compounded interest is
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]where A is the future value, P is the principal value, r is the annual rate, and n is the number of compounding periods.
The problem compounds quarterly, hence, we have n = 4.
We derive the working equation to solve for t, as follows:
[tex]\begin{gathered} \frac{A}{P}=(1+\frac{r}{n})^{nt} \\ \ln (\frac{A}{P})=\ln ((1+\frac{r}{n})^{nt}) \\ nt\ln ((1+\frac{r}{n}))=\ln (\frac{A}{P}) \\ t=\frac{\ln (\frac{A}{P})}{n\ln ((1+\frac{r}{n}))} \end{gathered}[/tex]Substitute the values of A, P, n, and r on the derived equation above and solve for t, we get

What is the End behavior of the graph?The end behavior of the graph of a polynomial function is the behavior of the graph of as approaches positive infinity or negative infinity.
Now, we see from the graph that as x approaches a larger value, y values are getting increasingly negative. This means that as x approaches negative infinity, the values of y approach negative infinity.
In a similar approach, we can see that as the values of x approach positive infinity, the values of y also approach positive infinity.
Thus, we can say that option D is correct.

assume 11% of the population is left-handed. assume this percentage is also true for all college students. a random sample of 209 college students from a campus with 5225 students is taken and whether or not they are left-handed is recorded.
After finding the probability we find that 0.04 students are left-handed from the 209 students randomly selected from the campus.
11 % of the population is left-handed so here we have to find the probability of left-handed students if 209 random students are selected from 5225 students on campus here Favorable outcome is 209 and the total outcome is 5225, so the favorable outcome upon the total number of the outcome.
According to the probability formula :

The population of rabbits by the year 2023 is 13985.
What will the population be?We have to use the following exponential function. This will be:
y = a b^t
In 2008 means, t=0
So we have 7100 = a b^0
a = 7100
y = 7100b^t

From the scatter plot of sales of Ceiling Fan in relation to Temperature.
(a) We are asked to characterized the money spent on Ceiling Fan to Temperature.
The relationship between the money spent on Ceiling Fan and Temperature is positive correlation.
When the y variable tends to increase as the x variable increases, we say there is a positive correlation. Which we can see in the scatter plot in the question.
(b) using the function y = 20x + 0, we are to find the predicted amount of sales if temperature is 21 degrees Celsius.
With the function:
y = 20x + 0
When Temperature is 21 degrees that means x = 21
So let's input x = 21 into the given function.
y = 20(21) + 0
y = 420 + 0
y = 420
Therefore, the predicted amount of sales when Temperature is 21 degrees Celsius is $420.
(c) What does the number 0 in the function mean in the contest of this situation?
In a linear interpretation which the function represents, the number 0 can be seen as the y intercepts of the function.
