Answer:
Yes
3
Step-by-step explanation:
a direct variation is written in the form
y = kx
k is a constant which is usually non zero.
6y = k18x
k = 3
An increase in x would lead to an increase in y

Amelia goes to Macy’s and buys a pair of shoes. The shoes are $115.95 on sale for 30% off. What is the total she will pay with 6% sales tax included?
Answer:
$86.03
Step-by-step explanation:
30% off = 70% of total price. Add .06 to 1 for 6% sales tax.
($115.95*(.70))*1.06
= $86.03

Solve this system of equations.
3x + 4y = 36
y=-2 +8
Answer:
( X, y [tex] = (x.y) ( - \frac{4?}{?3} = 10)[/tex]Standard form [tex]3 \times + 4y = 36 \\ y = 10[/tex]What is the answer ???????????????
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
y = 4x - 9 → (1)
y = x - 3 → (2)
Substitute y = 4x - 9 into (2)
4x - 9 = x - 3 ( subtract x from both sides )
3x - 9 = - 3 ( add 9 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations for y
Substituting into (2)
y = 2 - 3 = - 1
solution is (2, - 1 )

Step-by-step explanation:
Which equations for the measures of the unknown angles x and y are correct? Check all that apply. x = cos–1(StartFraction a Over c EndFraction) x = sin–1(StartFraction c Over b EndFraction) x = tan–1(StartFraction c Over a EndFraction) y = sin–1(StartFraction a Over c EndFraction) y = cos–1(StartFraction c Over b EndFraction)
the answers are:
b. x = sin -1 (c/b)
c. x = tan -1 (c/a)
e. x = cos -1 (c/b)
The population of New York state can be modeled by:
P(t) = 19.71/(1+61.22e^(-0.03513t))
Where P is the population in millions and t is the number of years since 1800. What is New York's maximum sustainable population?
Answer:
The answer is "19.71 million".
Step-by-step explanation:
[tex]\to P(t) = \frac{19.71}{1+61.22 e^{(-0.03513t)}}[/tex]
where
[tex]\to p= \text{population in million} \\\\\to t= \text{time in years}\\[/tex]
when t is increases, then [tex]61.22 \ e^{-0.035 t}=\frac{61.22}{e^{0.035t}}[/tex] when decrease so that p(t) continually grows in size to reach the optimum population which you find if t is quite high [tex]t \to \infty[/tex]
[tex]\to P_{max} = \lim_{ \ t \to \infty} \frac{19.71}{1+61.22 e^{(-0.03513t)}}[/tex]
[tex]when \ t \to \infty \ , 0.035 t \to \infty \ , e^{(0.03513t)} \to e^{\infty} \to \infty\ \ e^{\frac{1}{0.035t} = \ e^{-0.035t}} \to 0[/tex]
[tex]= \frac{19.71}{1+0}\\\\= \frac{19.71}{1}\\\\ = 19.71 \ million[/tex]

The boiling point of water is 100 degrees Celsius. Write an inequality to represent a pot of water that is not boiling.
Answer: x < 100 , where x = the temperature of a pot of water ( in degrees Celsius).
Step-by-step explanation:
The boiling point of water is 100 degrees Celsius.
The temperature of water that is not boiling must be less than 100 degrees Celsius.
Let x be the temperature of a pot of water ( in degrees Celsius).
Then, as per given,
x < 100
hence, the inequality to represent a pot of water that is not boiling.:
x < 100
Find the mean of the data plot below.
=============================================
Explanation:
The dot plot indicates we have this data set: {20, 23, 25, 28}
Add up those values to get 20+23+25+28 = 96
Then divide by 4 since there are 4 values being added up here
96/4 = 24
So the arithmetic mean is 24.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
Is the function representing the weekly paycheck amount of Salesman A a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman B a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman C a proportional relationship? Use complete sentences to explain your reasoning.
Answer:
See below
Step-by-step explanation:
Proportional relationship formula:y = kxAs per given we have:
Salesman A
p(s) = 65s (p = $1300 maximum)This is a proportional relationship, $65 per each sale. But this is restricted to 20 sales.Answer is yes (ignoring the restriction)Salesman B
p(s) = 40s + 300This is a linear but not proportional relationshipAnswer is noSalesman C
p(s) = 900There is no relationship between sales number and weekly earning as it is a fixed salaryAnswer is nosolve log(x-1) + 5x=2

Which line is wrong?
Write an equation in slope intercept form of the line that passes through (-2,10) and (1,1).
Answer:
(-2,10)=x1,y1
(1,1)=x2,y2
we have,
(y-y1)=(y2-y1)/(x2,x1)[(x-x1)]
(y-10)=(1-10)/(1+2)[x+2]
y-10=-9/3(x+2)
y-10=-3(x+2)
y-10=3x+6
y=3x+16
Answer:
y = -3x + 4Step-by-step explanation:
The slope of a line passing through two points: (x₂, y₂) and (x₁, y₁) is:
[tex]\bold{m=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(-2, 10) ⇒ x₁ = -2, y₁ = 10
(1, 1) ⇒ x₂ = 1, y₂ = 1
So:
[tex]\bold{m=\dfrac{1-10}{1+2}=\dfrac{-9}{3}=-3}[/tex]
The point-slope form of equation of line is y - y₀ = m(x - x₀)
We can pick any of given poins, so:
x₀ = 1, y₀ = 1 and m = -3
y - 1 = -3(x - 1)
y = -3x + 3 + 1
y = -3x + 4 ← slope intercept form of the line

A circular field has arey 144001 square feet.
What is the radius of the field?
Answer:
about 214.1
Step-by-step explanation:
Since pi r squared is the formula for a circle's area, you would do the opposite. First, you would divide 144001 by pi which is about 45,836.94. Then, you would find the square root of that which is about 214.1.
Carl is having a party. He has bought 24 brownies and is making 6 more batches of brownies. The inequality below can be used to determine how many brownies, b, must be in each batch so that all 138 guests get at least 1 brownie. Determine which of the given values, if any, make the inequality true: b=10, b=15, b=20 *
Answer:
b = 20
Step-by-step explanation:
The computation is shown below
Given that
24+ 6b > 138
where
b = 10
b = 15
b = 20
So if we take b = 10
= 24 + 6(10)
= 24 + 60
= 84
B = 15
= 24 + 6(15)
= 24 + 90
= 114
B = 20
= 24 + 6 (20)
= 24 + 120
= 144
So if we take b = 20 the inequality would be true
