The function w(x) = 0.15x + 500 represents the relationship between Stephanie's wages and her monthly sales.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
Let's suppose the Stephanie's wages is w and weekly sale is x
So we can model a function:
[tex]\rm w(x) = \dfrac{15}{100}x+500[/tex] or
w(x) = 0.15x + 500
Thus, the function w(x) = 0.15x + 500 represents the relationship between Stephanie's wages and her monthly sales.

Which equation is equivalalent to 2x²-24x-14=0
A. (x-6)²=50 B. (x-3)²=13 C. (x-3)²=20 D. (x-6)²=43
Answer:
D
Step-by-step explanation:
2x²-24x-14=0
2(x²-12x-7)=0
x²-12x-7=0
Expand A, B, C, D
A. (x-6)²=50 => x²-12x+36=50 => x²-12x-14=0 [not correct]
actually from here you can see B, C are not correct
D. (x-6)²=43 => x²-12x+36=43 => x²-12x-7=0 [correct)

Students were asked to choose their favorite season and 6/9 chose either spring or summer. If 5/9 chose spring, what fraction chose summer?
The fraction of people who chose summer is 1/9.
What is a Fraction ?Fraction is a number that represents the part of the whole.
It is given that
The fraction of people who chose either spring or summer = 6/9
This can also be represented as P( Spring ∪ Summer) = 6/9
P( Spring ∪ Summer) = P( Spring ) + P( Summer) ---------- (1)
It is also given that
The fraction of people who chose spring = 5/9
The fraction of people who chose summer = ?
From the equation 1
6/9 = 5/9 + P( Summer)
P( Summer) = 1/9

Dalia buys a winter jacket at a used clothing store that costs $30. She lives in Idaho, where the sales tax is 6%. Write an equation that represents the total cost, c, of any item bought in Idaho whose price is p.
Dalia buys a backpack at a different store in Idaho. It is on sale for 30% off. Dalia pays $33.39 total (including sales tax). What was the original price of the backpack?
Answer:
Step-by-step explanation:
Discussion
Question One
The first question is just to derive a formula that represents the cost of anything bought in Idaho.
c = p + 6/100 * p
c = p + 0.6 * p
c = 1.06 p
Question Two
The second question requires an entirely different formula. You don't use the first formula. You just use it's idea. Further, you take the sales tax only when you know how much money has exchanged hands.
c = (p - 30/100 p) + 6/100*(p - 30/100 * p)
c = (p - 0.3p) + 0.06* (p - 0.3p)
c = 0.7 p + 0.06*(0.7p) Combine the right side
c = 0.7p + 0.042p Combine
c = 0.742p
33.39 = 0.742p Divide by 0.742
33.39/0,742 = p
p = 45 dollars
The original cost was 45 dollars

Which equation represents the line that passes through the point (-9, -3) and has a slope of -6?
Answer:
y = -6x - 57
Step-by-step explanation:
We are given that a line passes through the point (-9, -3) and has a slope of -6
We want to write the equation of this line.
There are 3 ways to write the equation of the line, with the most common way being slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y-intercept
As we are already given the slope of the line, we can immediately plug that in the equation for m
Substitute m with -6.
y = -6x + b
Now we need to find b
As the equation passes through the point (-9, -3), we can use its values to help solve for b.
Substitute -9 as x and -3 as y.
-3 = -6(-9) + b
Multiply
-3 = 54 + b
Subtract 54 from both sides
-57 = b
Substitute -57 as b in the equation.
y = -6x - 57

The epicenter of an earthquake is the point on Earth's surface directly above the earthquake's origin. A seismograph can be used to determine
the distance to the epicenter of an earthquake. Seismographs are needed in three different places to locate an earthquake's epicenter. Find the
location of the earthquake's epicenter if it is 4 miles away from A (5,2), 3 miles away from B (-2,2), and 5 miles away from C (1, -3).
Answer:
The coordinates of the epicenter are (1,2) ie x=1, y =2
Step-by-step explanation:
We use the fact that the distance d between 2 points, (C y₁) and (x₂, y₂) is computed by the Pythagorean formula:
(x₁ - x₂)² + (y₁ - y₂) = d²
Let the epicenter be located at (x, y)
Distance dA from point A(5,2) is known to be 4 and is given by the equation:
(x-5)² + (y - 2)² = dA² = 4² = 16 ==>
(x-5)² + (y-2)² = 16 (1)
Similarly, the distance from point B(-2,2) is given as 3. Therefore,
(x - (-2))² + (y-2)² = 3² = 9 or
(x + 2)² + (y-2)² = 9 (2)
Distance from point C(1,-3) ==>
(x-1)² + (y-(-3))² ==> (x-1)² + (y +3)² = 25 ...(3)
(1) - (2) cancels out the y terms and gives us
(x-5)² - (x+2)² = 7 (4)
This simplifies to
x² + -10x + 25 - (x² +4x + 4) = 7
or
x² + -10x + 25 -x² -4x - 4 = 7
-10x -4x = 7 - 21 = -14
Therefore, -14x = -14 giving us x = 1
Substituting for x = 1 in equation (3) gives us
(1-1)² + (y+3)² = 25 or
y + 3 = √25 = 5 giving y = 2
So we get the epicenter coordinates as x=1, y =2
Crosscheck in each of the equations (1), (2) and (3) for consistency
Equation 1 : (1-5)² + (2-2)² = -4² = 16 Check!
Equation 2: (1-(-2))² + (2-2)² = (1+2)² = 3² = 9 Check!
Equation 3: (1-1)² + 2-(-3))² = (2+3)² = 5² Check!

Answer:
151 in
Step-by-step explanation:
circumference = 2πr
where r = radius
given radius appears to be 24 so r = 24
so we have C = 2πr and r = 24 and we use 3.14 for π
So C = 2(3.14)(24)
==> multiply 2 and 3.14
C = 6.28(24)
==> multiply 6.28 and 24
C = 150.72
The closest answer is 151 so that is the answer

Formula for arc length =
arc length = r θ where θ is in radians
So we have
2pi = 5 θ solve for θ and we have that

The equation that shows the miles Andrea drove is $104 = $50 + $3x.
What is the equation that shows the miles Andrea drove?The total cost of renting the moving truck is a function of the cost to rent per day and the total miles driven. The cost to rent the truck per day is the fixed cost while the cost per mile is the variable cost.
