Answer:
y = -1/3 x
Step-by-step explanation:
what is the slope intercept form for x+3y=0
Slope intercept form solves for y:
x + 3y = 0
subtract x from both sides:
x + 3y - x = 0 - x
3y = -x
divide both sides by 3:
3y/3 = -x/3
y = -1/3 x

The value of the quotient expression 546 ÷ 13 is 42
How to evaluate the expressions?The expression is given as
546 divided by 13
Rewrite the expression as
546 ÷ 13
By the standard algorithm, we have
The expression can be solved using a calculator and with the use of standard algorithm i.e. partial decomposition
By the rule of partial decomposition, we have
a ÷ b = (c ÷ d) ÷ b
Where
a = c + d
Next, we expand the expression as follows:
546 ÷ 13 = (520 + 26) ÷ 13
Remove the brackets
So, we have
546 ÷ 13 = 520 ÷ 13 + 26 ÷ 13
Evaluate the quotients
So, we have
546 ÷ 13 = 40 + 2
Evaluate the sum
So, we have
546 ÷ 13 = 42
Hence, the solution of 546 ÷ 13 is 42

A farmer has 80 animals on his farm.The animals consist of cows and chickens .Given there are 216 legs altogether among the animals, how many cows are there?
The farmer has 28 cows from a total of 80 animals in the farm.
How many cows and chickens does the farmer have in the farm?
Each chicken has two legs and each cow has four legs. The farmer has a total of 216 legs among all the animals, which are 80. Then, we can represent the situation with the following system of linear equations:
x + y = 80
4 · x + 2 · y = 216
Where:
x - The number of cows.y - The number of chickens.The system can be solved easily by some algebraic handling:
x = 80 - y
4 · (80 - y) + 2 · y = 216
320 - 4 · y + 2 · y = 216
320 - 2 · y = 216
2 · y = 320 - 216
2 · y = 104
y = 52
x = 80 - 52
x = 28
The farmer has 28 cows.

Find the slope of the line that contains the given point
Answer:
(2, 1) and (4, 2): [tex]\frac{1}{2}[/tex]
(-4, 5) and (-3, -7): [tex]-12[/tex]
Step-by-step explanation:
Hello! Let's help you with that problem there!
So we know that in a slope intercept form, it is depicted as [tex]y=mx+b[/tex]. There are two ways to essentially find m, which is slope in this case. The first method is the [tex]\frac{rise}{run}[/tex] method. This is typically used when you have a graph to look off from and it's just a matter of counting the displacement from one point to another.
However, there is another way to find the slope given 2 points and that is what we are going to do here, since we have no graph to reference and have all the relevant information to find the slope using this formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
With this formula, we can plug in the coordinate values and solve for the slope!
(2, 1) and (4, 2):
[tex]m=\frac{2-1}{4-2}[/tex]
[tex]m=\frac{1}{2}[/tex]
Therefore, the slope of these points is [tex]m=\frac{1}{2}[/tex]
(-4, 5) and (-3, -7):
[tex]m=\frac{-7-5}{-3-(-4)}[/tex]
[tex]m=\frac{-12}{1}[/tex]
[tex]m=-12[/tex]
Therefore, the slope of these points is [tex]m=\frac{-12}{1}[/tex] or [tex]m=-12[/tex]

Sam counted 12 liters of hand sanitizer in the storage cabinet . He fills the seven of the examination rooms as follows : 350 mL , 600 mL , 475 mL, 580 720 , and 500 mL .a)How many total milliliters did sam use to fill the dispensers?B) After filling the dispensers, how many liters of sanitizer remain in the storage cabinet?
a) To know the total millilites that sam use to fil the dispenser, we will have to add all the seven amount filled as shown;
Total (in milliliters) = 350 mL + 600 mL + 475 mL + 580mL + 720mL + 500 mL
Total (in milliliters) = 3225mL
Hence the total milliliters that sam use to fill the dispensers is 3225millilitres
b) The amount liters of sanitizer remaining will be 12litres - 3225mL
Convert 3225mL to litres
3225mL = 3225/1000 Litres
3225mL = 3.225litres
The amount liters of sanitizer remaining = 12 - 3.225
The amount liters of sanitizer remaining = 8.775litres

Directions: Write the slope form of the equation with the given information.
13) through (3,4) and (5,-2)
Answer:
y=-3x+13
Step-by-step explanation:
step one you will need to find the slope by the Y2 minus y1 all over x2 minus X1 formula. so you would have -2 - 4 all over 5 - 3 . you will get -6 over 2 which is equal to -3 . that means that -3 is the slope .
Step 2 you can find the equation with the point slope form formula . the point slope form formula is y-y1=m(x-x1). by substituting your values into these equation you can find the equation of this line . you can substitute any point into it as long as it is on the line . let's use (3,4) where 3=x1 and 4=y1.
step 3. simplify. you will get y-4=-3(x-3). keep in mind I substituted -3 into the equation because -3 is the slope.
you can simplify this if you want to . you will get y=-3(x-3)+4. it becomes through foiling, y=-3x+9+4. it simplifies to y=-3x+13.

Answer:
∠ 2 = 140°
Step-by-step explanation:
the left base angle in the triangle and 110° are a linear pair and sum to 180°
base angle + 110° = 180° ( subtract 110° from both sides )
base angle = 70°
the 2 sides of the triangle are congruent so Δ is isosceles with base angles congruent.
the vertex of the Δ is then
(180 - 70 - 70)° = 180° - 140° = 40°
the vertex and ∠ 2 are a linear pair and sum to 180° , that is
∠ 2 + 40° = 180° ( subtract 40° from both sides )
∠ 2 = 140°
for a population with a standard deviation of σ = 6, what is the z-score corresponding to a score that is 12 points above the mean?
The z-score corresponding to a score that is 12 points above the mean is 2.
The z-score is a numerical measurement used in statistics to determine the sample data value's relationship to the mean of a group of values, measured in terms of standard deviation from the mean. It is measured as the difference of the sample data value and the sample mean over the standard deviation, such that
z-score = (x – μ) / σ
where x = sample data value
μ = mean
σ = standard deviation
If the sample score is 12 points above the mean, then (x – μ) = 12.
(x – μ) = 12
σ = 6
Substitute the values to the z-score formula.
z-score = (x – μ) / σ
z-score = 12/6

Write the equation of the linear function:

Required Lagrange multipliers are 14,14.
What are Lagrange multipliers?
In multivariable calculus, Lagrange multipliers are used to locate the maximum and minimum of a function that is subject to restrictions.An approach for locating a function's maximum or minimum is the Lagrange multiplier method.The growth in the optimization problem (f(x, y)) that results from a marginal relaxation of the constraint is quantified by the Lagrange multiplier.We have to minimize f(x,y)=x+y'
subject to xy=196 ............(1)
x>0,y>0
Let L(x,y,d)= f(x,y)+d(XY-196)
∀L= [tex](\frac{Lx}{Ly} )=(\frac{1+dy}{1+dx} )[/tex]
For critical points,
∀L=0
⇒[tex](\frac{1+dy}{1+dx} )=\frac{0}{0}[/tex]
⇒ x,y= -1/d
Substituting in equation 1, we get,
d=±1/14
d=+1/14 ⇒ x=y=-14 (neglect)
d=-1/14 ⇒ x=y=+14
∵ x>0, y>0.
Hence, x=y=14

24 students in a class took an algebra test
If 18 students passed the test, what percent passed
Answer:
only 75% of the class or students passed the algebra test
Answer: 75%
Step-by-step explanation: The equation for percentages is: part = percent • whole.
We can use our given values and plug them into the equation to solve for our percent.
In this problem, the “part” is 18, and our “whole” is 24, since the whole class has 24 people, and part of the class (18) passed.
P = % • W
18 = % • 24
(to solve for %, we have to get isolate it, or get rid of the • 24. We use division, the opposite operation, to cancel our • 24.)
18 = % • 24
÷24 ÷24
0.75 = %
Since percents are out of 100, we have to multiply 0.75 by 100.
0.75 • 100 = 75%
