4y - 7x = 0 is the equation of the line in standard form.
How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
See, that was so simple, using the mentioned methods, every linear equation can be solved easily.
To find standard equation of a line we will use points (0,0) and (80,140)
Lets fine the slope of given data, slope, m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
m = [tex]\frac{140- 0}{80- 0}[/tex]
m = 140/80
m = 7/4
We can now make the slope intercept form that is y = mx
with the given data,
y = 7/4(x)
4y = 7x
subtract 7x both the side and we get
4y - 7x = 0

Find the 32 nd term of each sequence. 23,30,37,44, ...........
The 32nd term of the arithmetic sequence AP is calculated to be 240.
What basically is an AP arithmetic sequence?In mathematics, an arithmetic progression (AP) is a list and possibly sequence of numbers where each term is collected by adding a sequence towards the term before it.
The fixed number, without regard to arithmetic progression, is signified by the letter 'd.'Common difference => d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1.nth term of AP: an = a + (n - 1) dThe sum of n terms of an AP's => Sn = n/2(2a+(n-1)d) = n/2(a + l), where l = last term of the AP.Finally, here is the answer to the question:
The following are the numbers with in displayed sequence:
23,30,37,44, ...........
The 32nd number in the series must be investigated because it contains 32 terms.
The common difference between two consecutive terms of an AP that are equal is denoted by the letter 'd.'
Let's consider the first term is'a₁' = 23.
Let's consider 'a₂' = 30 is the second term.
Let's consider the third term is 'a₃' = 37.
Substitute the values the above obtained equation; the 32nd term is-
d = a₂ - a₁
Estimate the common difference;
d = 30 - 23
d = 7
Substitute the values in the next formula; the 32nd term is
The formula given will estimate the nth term equation;
nth term of an AP: an = a + (n - 1) d
Total number of terms ; n = 32
Initial term is a = 23
Common difference d = 7
Substitute the given values in nth term formula;
a₃₂ = a + (n - 1) d
a₃₂ = 23 + (32 - 1)(7)
a₃₂ = 23 + 217
a₃₂ = 240
Thus, the 32nd term value of the given arithmetic sequence is estimated to be 240.

When the numerator and denominator of a rational number have no common factor other than 1, we consider it to be its simplified version in fractions. The same method may be used to simplify rational expressions; the only difference is that polynomials are included in the fraction.

At Sweet Stuff Fresh Produce the price of a bag of grapes depends on the total number of bags purchased at 1 time, as shown in the table below. In 2 trips to Sweet Stuff this week, Janelle purchased 3 bags of grapes on Monday and 4 bags of grapes on Wednesday. How much money would Janelle have saved if she had instead purchased 7 bags of grapes in 1 trip on Monday?
The amount that would be saved if 7 bags of grapes were bought on Monday is $2 (option J).
How much would be saved?The total cost of items bought on Monday and Wednesday would be added together. This amount would be subtracted from the total cost if the items were all bought on Monday.
The first step is to determine the total cost of the grapes bought on Monday and Wednesday.
Total cost of grapes = cost of grapes bought on Monday + cost of grapes bought on Wednesday
Cost of grapes bought on Monday = number of bags bought x price per bag
3 x $3 = $9
Cost of grapes bought on Wednesday = number of bags bought x price per bag
4 X $2.80 = $11.20
Total cost = $9 + $11.20 = $20.20
Cost or the 7 bags of grapes purchased in 1 trip = number of bags bought x price per bag
7 x $2.60 = 18.20
Amount saved = $20.20 - $18.20 = $2

What do we mean by multivariable calculus?Multivariable calculus (also known as multivariate calculus) is the extension of one-variable calculus to multivariable calculus: the differentiation and integration of functions involving multiple variables rather than just one.Multivariable calculus is a fundamental component of advanced calculus. Calculus on Euclidean space is an advanced calculus topic.So,
To find the curve:
[Vector Field] Set up [curl F]:
[tex]Curl F=\left|\begin{array}{ccc}\hat{1} & \hat{\jmath} & \hat{k} \\\frac{\partial}{\partial x} & \frac{\partial}{\partial y} & \frac{\partial}{\partial z} \\7 x y e^z & 0 & y z e^x\end{array}\right|[/tex]

Simplify [2x2 Matrix Determinant] with [curl F]:
[tex]Curl F=\left[\frac{\partial}{\partial y} y z e^x-\frac{\partial}{\partial z} 0\right] \hat{\mathrm{i}}-\left[\frac{\partial}{\partial x} y z e^x-\frac{\partial}{\partial z} 7 x y e^z\right] \hat{\mathrm{\jmath}}+\left[\frac{\partial}{\partial x} 0-\frac{\partial}{\partial y} 7 x y e^z\right] \hat{\mathrm{k}}[/tex]
The partial derivatives can be differentiated using the basic differentiation techniques listed above under "Calculus":
[tex]\begin{aligned}&\frac{\partial}{\partial y} y z e^x=z e^x \\&\frac{\partial}{\partial z} 0=0 \\&\frac{\partial}{\partial x} y z e^x=y z e^x \\&\frac{\partial}{\partial z} 7 x y e^z=7 x y e^z \\&\frac{\partial}{\partial x} 0=0 \\&\frac{\partial}{\partial y} 7 x y e^z=7 x e^z\end{aligned}[/tex]
When we substitute our partial derivative values, we get:
[tex]\begin{aligned}Curl F&=\left(z e^x-0\right) \hat{1}-\left(y z e^x-7 x y e^z\right) \hat{\jmath}+\left(0-7 x e^z\right) \hat{k} \\&=z e^x \hat{\imath}-\left(y z e^x-7 x y e^z\right) \hat{\jmath}-7 x e^z \hat{k}\end{aligned}[/tex]
So, we've discovered the curl of the given vector field.
Therefore, the curl of the vector field is:

The solution of the given linear equation in one variable 5(s -12) - 24 = 3(s + 2) is at s = 45.
According to the given question.
We have an equation.
5(s -12) - 24 = 3(s + 2)
Since, we have to solve the above linear equation in one variable.
As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
Thereofre, the solution of the linear equation in one variable 5(s -12) - 24 = 3(s + 2) is given by
5(s - 12) -24 = 3(s + 2)
⇒ 5s - 60 - 24 = 3s + 6 ( by distributive rule)
⇒ 5s - 84 = 3s + 6

The medical examiner is called in to determine how long a person has been deceased. The rate of decay is -0.026 and the temperature outside is 55 degrees. When the medical examiner arrives the temperature of the body was 82 degrees. Assuming the person had a normal body temperature of 98.6 degrees when they passed, how long had the person been deceased? Round answer to the nearest hour.
The person had been deceased for 12 hours
According to given data,
Temperature of normal person had 98.6 degrees,
and the temperature of the person was 82 degrees
outside temperature is 55 and
rate of decay is -0.026
The temperature of body drops :
98.6 - 82 = 16.6 degrees
[tex]\frac{16.6}{55}[/tex] ≈ 0.3
[tex]\frac{0.3}{0.026}[/tex] ≈ 12 hours
therefore, 12 hours had the person been deceased
