In linear equation, y ≥ x + 12/3 is simple version .
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.y ≥ 1/3 x + 4
y ≥ x/3 + 4
y ≥ x + 12/3

MAPS Leila is walking from the park at point P to a restaurant at point R. She wants to stop for a break when the distance she has traveled and the distance she has left to travel has a ratio of 3:5. At which point should Leila stop for her break?
The point at which Leila should stop to take break is (6.25 , 3.75)
Given P(10 , 3) and R (0 , 4)
The ratio is 3:5
Let the break point be point B.
The formula is : (n(x₁) ₊ m(x₂)/ m₊n , n(y₁) ₊ m(y₂)/ m₊n)
P(10,3) = (x₁ , y₁)
R(0,4) = (x₂ , y₂)
m:n = 3:5
B = (5(10) ₊ 3(0)/3₊5 , 5(3) ₊ 3(4)/3₊5)
B = (50₊0/8 , 15₊12/8)
B = (50/8 , 27/8)
B = (6.25 , 3.75)
Hence Leila should stop at point (6.25 , 3.75) for her break.

Ms. Jordan bought a box of 32 granola bars. Every day each of her three children ate one granola bar for lunch. Now there are only 11 bars left. Which equation can be used to find the number of days, n, that the children ate the bars for lunch? 32 =-11 32 = 3n - 11 ○ 32 = 3 +11 32 = 3n+ 11
The equation that can be used to find the number of days is 32 - 3n = 11
How to determine the equation that can be used to find the number of days?The given parameters are
Initial amount = 32
Rate = 3 i.e. 3 children
Amount left = 11
Let the number of days be n
So, we have:
Initial amount - number of days * rate = amount left
This gives
32 - 3n = 11
Hence, the equation that can be used to find the number of days is 32 - 3n = 11

(-23/20) in a decimal form long division will be equal to (-1.15)
As per the question statement, we are provided with a fraction: (-23/20).
We are required to calculate the simplest form of the fraction in decimals using to the long division method.
The long division method works with 4 component: dividend, divisor, quotient and remainder. And the steps to perform the long division method are as follows:
Step 1: To take the first digit of the dividend from the left and check if this digit is greater than or equal to the divisor.
Step 2: Then, to divide it by the divisor and write the answer on top as the quotient.
Step 3: To subtract the result from the digit and write the difference below.
Step 4: To bring down the next digit of the dividend (if present).
Step 5: To Repeat the same process.
Hence, converting the fraction (-23/20) to decimal values using the process of long division method mentioned above, we get (-1.15).

She invests a portion of the money in a bank certificate of deposit (CD account) which earns 4% and the remainder in a savings bond that earns 7%. If the total interest earned after one year is $900.00, how much money was invested in the CD account?
The total interest earned after one year is $900.00.
How much money was invested in the CD account? $
(Round to the nearest cent, if necessary.)
From the analysis of the above math, the amount she invested in the CD account is 5,000. See the analysis below.
What is the analysis showing the above answer?Let A be the amount invested in the CD.
Let B be the amount invested in the savings bond.
A + B = 15, 000
.04A + .07B = 900
Multiply the first equation by -.04 and add it to the second equation to get rid of the A term.
-.04A-.04B = -600 add this equation to the second equation.
.03B = 300 multiplying by 100. 3B = 30,000
dividing by 3 on both sides: B = 10,000. So A = 5,000

Find constants and in the function ()= such that (12)=1 and the function has a local maximum at =12
When the function changes from increasing to decreasing, a local maximum occurs. The value of a = 5e.
What is meant by local maximum?A local maximum point on a function is a point (x, y) on the function's graph whose y coordinate is greater than all other y coordinates on the graph at "close to" points (x, y).
When the function changes from increasing to decreasing, a local maximum occurs. This means that the function's derivative will shift from positive to negative.
Let the function be [tex]&F(x)=a x e^{b x} \\[/tex]
[tex]&F '(x)=d / d x\left(a x e^{b x} ) \\[/tex]
[tex]&=a(d / d x)\left(x e^{b x}) \\[/tex]
simplifying the above equation, we get
[tex]&=a\left[\left(d / d x* x\right) e^{b x} +\left(x* d / d x* e^{b x} )\right] \\[/tex]
[tex]&=a\left[e^{b x} +b x e^{b x} \right] \\[/tex]
[tex]$&=a[1+b x] e^{b x}[/tex]
For critical points, set [tex]$f^{\prime}(x)=0$[/tex] and solve for x
[tex]&a[1+b x] e^{b x} =0 \\[/tex]
simplifying the above equation, we get
1 + bx = 0
bx = -1
x = -1/b
The value of x = -1/b
Given that f(x) has local max at 1/5, critical point x = 1/5 then
-1/5 = -1/b
Therefore, b = -5
[tex]&F(x)=a x e^{-5x}\\[/tex]
[tex]&F(1 / 5)=a / 5 e^{-1}\\[/tex]
1 = a/5e
Therefore, the value of a = 5e.

3x + 10 + 2x - 5 = 90
Collect the like terms
So, we have
3x + 2x + 10 - 5 = 90
Evaluate the like terms
So, we have

$2
$4
$5
$6
The answer is 6.
6x4=24
and that leaves the water to =2 per bottle.
so, 24+4=28
Answer:
$6.00
Step-by-step explanation:
To solve this problem, we have to construct two separate equations for each family, and then use any of the methods for solving simultaneous equations.
Let's consider h to represent the cost of 1 hot dog, and w to mean the cost of 1 water bottle.
• For the first family:
[tex]2h + 3w = 18[/tex]
We can rearrange the equation to make w the subject:
⇒ [tex]3w = 18 - 2h[/tex]
⇒ [tex]w = \frac{18 - 2h}{3}[/tex]
• For the second family:
[tex]4h + 2w = 28[/tex]
Since we have previously obtained an expression for w in terms of h, we can substitute that expression for w in the above equation, and then solve for h:
⇒ [tex]4h + 2(\frac{18 - 2h}{3}) = 28[/tex]
⇒ [tex]4h + \frac{36 - 4h}{3} = 28[/tex]
⇒ [tex]12h + 36 - 4h = 84[/tex] [Multiplying both sides of the equation by 3]
⇒ [tex]8h + 36 = 84[/tex]
⇒ [tex]8h = 48[/tex]
⇒ [tex]h = \bf 6[/tex]
∴ The price of one hot dog is $6.00.
The cost of one hot dog at an amusement park is $6.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x - 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Let, the cost of hot dogs is 'x' and the cost of bottles of water be 'y'.
From the given information the two linear equations can be formed as,
2x + 3y = 18...(i) and 4x + 2y = 28...(ii)
Multiplying equation (i) by 2 and subtracting form (ii) we have,
4x + 2y = 28.
(-) 4x + 6y = 36
_____________
- 4y = - 8.
y = 2.
And hence x is equal to, 4x + 4 = 28 ⇒ 4x = 24 ⇒ x = 6.
