Answer:
y = -3x + 19
Step-by-step explanation:
Slope , m , = (y1-y2) / (x1-x2) = (1-4)/(6-5) = - 3
y = -3 x + b <======= sub in one of the points to calculate 'b'
4 = -3(5) + b

a shoe store uses a 60% markup for all the shoes it sells what would be the selling price of a pair of shoes as a wholesale cost of $51
Answer:
81.60 is your selling price
Step-by-step explanation:
60% = 0.60
0.60 x 51 = 30.60
51 + 30.60 = 81.60
The selling price of shoes after a markup of 60% of the price will be equal to $81.60.
What is the Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
As per the given information in the question,
The wholesale price of shoes = $51
There is a markup of 60% on every shoe.
Then the price of shoes will be,
$51 + $51 × (60/100)
$51 + 30.6
= $81.60

10. A pipe whose diameter measures 1 1/4 inches should have less threads per inch than a pipe with a diameter of _______ inch.
A. 3
B. 1/2
C. 1
D. 11/2
A pipe whose diameter measures 1 1/4 inches should have less threads per inch than a pipe with a diameter of 11/2 inch. So, the correct answer is (D).
To determine the correct answer, we need to compare the diameters of the two pipes and understand the relationship between pipe diameter and threads per inch.
The number of threads per inch generally decreases as the pipe diameter increases. This means that a larger pipe diameter will have fewer threads per inch compared to a smaller pipe diameter.
Given that the first pipe has a diameter of 1 1/4 inches, we need to find the pipe diameter from the options that is larger than 1 1/4 inches.
The option that meets this requirement is D. 11/2. This represents a pipe diameter of 1 1/2 inches. Therefore, a pipe with a diameter of 1 1/2 inches should have fewer threads per inch than a pipe with a diameter of 1 1/4 inches. Therefore, the correct answer is D. 11/2.

After a 75% reduction, you purchase a new clothes dryer for $200. What was the original price of the clothes dryer?
Answer:
$800
Step-by-step explanation:
Let the original price be $x.
75% reduction ----- 100% -75%= 25%
25%x= 200
\( \frac{25}{100} x = 200 \\ x = 200 \div \frac{25}{100} \\ x = 200 \times \frac{100}{25} \\ x = 800\)
Thus, the original price of the clothes dryer is $800.
Answer:
$800
Step-by-step explanation:
Let the original price be x.
Final price=100%-75%
=25%
x-75%=200
x=200 x 100/75
x=8 x 100
x=800

An office manager needs to cover the front face of a rectangular box with a label for shipping. The vertices of the face are (–5, 8), (3, 8), (–5, –4), and (3, –4). What is the area, in square inches, of the label needed to cover the face of the box?
96 in2
48 in2
40 in2
20 in2
The area of rectangle is 96in2 which is option A.
Area of rectangle calculation.
To find the area of the rectangular face, we need to find the length and width of the rectangle, and then multiply them together.
The length of the rectangle is the distance between the points (-5,8) and (3,8), which is 8 - (-4) = 12 inches.
The width of the rectangle is the distance between the points (-5,8) and (-5,-4), which is 3 - (-5) = 8 inches.
Therefore, the area of the rectangular face is 12 x 8 = 96 square inches.
So the answer is 96 in².

Which of the following is the best first step to convert the following equation to slope
intercept form?
2-4y =-12
Answer: y=7/2 in decimal form 3.500
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2-4*y-(-12)=0
Pull out like factors :
14 - 4y = -2 • (2y - 7)
Solve : 2y-7 = 0
Add 7 to both sides of the equation :
2y = 7
Divide both sides of the equation by 2:
y = 7/2 = 3.500

5. What are the first five terms in the recursive sequence defined by the following?
a1 = 1
a₂ = 1
an = an-2+ An-1
(2, 3, 5, 8, 13)
(1, 1, 0,-1,-1)
(1,-1,2,-3, 5)
(1, 1, 2, 3, 5)
the first five terms of the sequence are (1, 1, 2, 3, 5). Option (d) correctly identifies this as the answer.
The problem provides a recursive sequence defined by the formula an = an-2 + an-1, where a1 = 1 and a2 = 1. We are asked to find the first five terms of this sequence.
To find the second term, we can use the formula and substitute n = 3:
a3 = a1 + a2 = 1 + 1 = 2
To find the third term, we can use the formula and substitute n = 4:
a4 = a2 + a3 = 1 + 2 = 3
To find the fourth term, we can use the formula and substitute n = 5:
a5 = a3 + a4 = 2 + 3 = 5
To find the fifth term, we can use the formula and substitute n = 6:
a6 = a4 + a5 = 3 + 5 = 8
Finally, to find the sixth term, we can use the formula and substitute n = 7:
a7 = a5 + a6 = 5 + 8 = 13
Therefore, the first five terms of the sequence are (1, 1, 2, 3, 5). Option (d) correctly identifies this as the answer.

A recipe for strawberry punch calls for 3/7 qt of ginger ale and 1/7 qt of strawberry soda. How much liquid is needed?
If the recipe is doubled, how much is needed?
If the recipe is halved, how much is needed?
Answer:4.7 qt of liquid is needed. If doubled, 8/7 qts of liquid is needed. if halved, 2/7 qts of liquid is needed.
Step-by-step explanation:
Add the two amounts of liquid to get the total amount of liquid:
1/7 qt + 3/7 qt = 4/7 qt (cannot be simplified further)
To double the recipe, multiply the total liquid amount by 2.
4/7 * 2/1 = 8/7
To half the recipe, multiply the total liquid amount by 1/2.
4/7 * 1/2 = 4/14 --> 2/7
The radioactive substance cesium-137 has a half-life of 30 years. The amount A (r) (in grams) of a sample of cesium-137 remaining after t years is
given by the following exponential function.
A (t)-266 6 (1) 10
Find the initial amount in the sample and the amount remaining after 50 years.
Round your answers to the nearest gram as necessary.
Initial amount:
Amount after 50 years:
The amount remaining after 50 years is approximately 45.5% of the Initial amount, A₀.
The given exponential function represents the amount A(t) (in grams) of cesium-137 remaining after t years:
A(t) = A₀ * (1/2)^(t/30)
We are asked to find the initial amount A₀ and the amount remaining after 50 years.
1. Initial amount:
The initial amount, A₀, is the amount of cesium-137 present at t = 0 years. To find A₀, we substitute t = 0 into the equation:
A(0) = A₀ * (1/2)^(0/30)
A(0) = A₀ * 1
Since anything raised to the power of zero is 1, we have A(0) = A₀ * 1, which simplifies to A(0) = A₀.
Therefore, the initial amount of the sample is A₀.
2. Amount after 50 years:
To find the amount remaining after 50 years, we substitute t = 50 into the equation:
A(50) = A₀ * (1/2)^(50/30)
Now we can calculate the amount using the given formula:
A(50) = A₀ * (1/2)^(5/3)
To round the answer to the nearest gram, we evaluate the expression and round the result to the nearest gram:
A(50) = A₀ * 0.455
A(50) ≈ A₀ * 0.455
Therefore, the amount remaining after 50 years is approximately 45.5% of the initial amount, A₀.

Solution :
Let X denotes the number of the households tha have a cable TV.
Percentage of household that have a cable TV = 85 %
\($X \sim \text{Binomial}(6, 0.85)$\)
Here, we can see that each of the observations is independent and the number of the observations is fixed, n.
The probability of the success P is the same for each of the outcomes.

thank you:)
Answer:
x + 2
Step-by-step explanation:
Area = x² + 11x + 18
length = x + 9
width = ?
Area = length x width
Factor the polynomial x² + 11x + 18:
length x width = (x + 9)(x + 2) = x² + 11x + 18
The length is x + 9, therefore the width is x + 2

f(x) = x³ + 2x - 1, a = -4
(f⁻¹)′( - 4) = ?
Recall the inverse function theorem. If \(f\) is invertible and differentiable in all the right places, then
\(f^{-1}\bigg(f(x)\bigg) = x \\\\ ~~~~~~~~ \implies \left(f^{-1}\right)'\bigg(f(x)\bigg) f'(x) = 1 \\\\ ~~~~~~~~ \implies \left(f^{-1}\right)'\bigg(f(x)\bigg) = \dfrac1{f'(x)} \\\\ ~~~~~~~~ \implies \left(f^{-1}\right)'(x) = \dfrac1{f'\left(f^{-1}(x)\right)} \\\\ ~~~~~~~~ \implies \left(f^{-1}\right)'(-4) = \dfrac1{f'\left(f^{-1}(-4)\right)}\)
Solve for \(x\) such that \(f(x)=-4\).
\(x^3 + 2x - 1 = -4 \\\\ x^3 + 2x + 3 = 0 \\\\ (x + 1) (x^2 - x + 3) = 0\)
\(x^2-x+3=0\) has non-real solutions, so we're left with
\(x+1 = 0 \implies x = -1\)
Then we have
\(f(-1) = -4 \implies f^{-1}(-4) = -1 \implies \left(f^{-1}\right)' (-4) = \dfrac1{f'(-1)} = \boxed{\dfrac15}\)
since
\(f(x) = x^3 + 2x - 1 \implies f'(x) = 3x^2 + 2 \implies f'(-1)=5\)
