Answer:
The most accurate answer is:
*4*
I hope I helped you!
Step-by-step explanation:
Alright, lets examine the problem; *12* slices of pizza are given. We also have *4* guests at the table, and each are given *2* slices. Lets use subtraction to solve: 12 - 2 - 2 - 2 - 2- the *2*'s equal the amount of pizzas given, and the *12* represents our amount of slices of pizza. We also gave 4 people 2 slices, which is why we have *4* *2*'s

A parabola has x-int of (-8,0) and (4,0) and a minimum value of -9 in intercept form
Answer:
The function is 1/4x^2 + x - 8
Step-by-step explanation:
In Factor form the function is
a(x + 8)(x - 4) where a is a constant to be found.
= a( x^2 + 4x - 32) Note the coefficient of x is positive because the function has a minimum value.
The line of symmetry is x = (-8+4)/2 = -2.
So the minimum value will be the value of f(x) when x = -2, so we have the equation
a(-2+8)(-2-4) = -9
-36a = -9
a = 1/4.
PLEASE HELP A store has sales of $500 in their first month. If sales increase at a rate of $10 each month, they can be modeled by this equation:an=500+(k-1)10 Use summation notation to model and evaluate the sales for the first ten years. Explain your steps.
Answer: 131,400$
Step-by-step explanation:
The sale for first month is $500.
The sale increases by $10 each month, as modelled by the equation:
a_k=500+(k-1)10
where, k = 1 (first month)
k = 2 (second month)
.... and so on.
we have to calculate the sale for the first 10 years, that means for 10*12 = 120 months (1 year = 12 months)
Total sales = ∑ a_k
∑ a_k = ∑ (500+(k-1)10)
= 500k + ∑ (10k - 10)
= 500k + 10∑k - 10k
= 490k + 10∑k
= 490k + 10 {k*(k+1)/2}
= 490k + 5{k*(k+1)}
= 490k + 5k^2 + 5k
= 5k^2 + 495k
∴∑ a_k = 5k^2 + 495k
For calculating the total sales of 10 years, we will put the value of k = 120 (120th month after the first month)
= 5*(120*120) + 495*120
= 72,000 + 59, 400
= 131,400$
Answer:
Distribute 10 to (k – 1) and simplify.
Rewrite the summation as the sum of two individual summations.
Evaluate each summation using properties or formulas from the lesson.
The lower index is 1, so any properties can be used. The upper index is 10*12=120.
The values of the summations are 58,800 + 72,600. So, the total sales is $131,400.

Enter the equations of the asymptotes for the function
Answer:
x = 7 and y = 2
Step-by-step explanation:
the denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non-zero for this value then it is a vertical asymptote
solve x - 7 = 0 ⇒ x = 7 is the asymptote
horizontal asymptotes occur as
[tex]lim( x → ± ∞), f(x) → c ( where c is a constant )
divide terms on numerator/ denominator by x
f(x) = (3/x/x/x -7/x ) + 2
as x → ± ∞, f(x) → 0 / 1 - 0 + 2 = 2
y = 2 is the asymptote
Answer: Vertical asymptote is x = 7
Horizontal asymptote is y = 2
Step-by-step explanation:
The vertical asymptote is the restriction on the domain (x-value). Since the denominator cannot be zero ⇒ x - 7 ≠ 0 ⇒ x ≠ 7 so the vertical asymptote is at x = 7.
The horizontal asymptote (H.A.) is the restriction on the range (y-value). There are three rules that determine the horizontal value which compare the degree of the numerator (n) with the degree of the denominator (m):
If n > m , then there is no H.A. (use long division to find the slant asymptote) If n = m , then the H.A. is the coefficient of n ÷ coefficient of mIf n < m, then the H.A. is y = 0In the given problem, n = 0 and m = 1 ⇒ n < m ⇒ H.A. is y = 0
Since there is a vertical shift of +2 units, the H.A. is y = 0 + 2 ⇒ y = 2

30. Write y=-3/4x-6 in standard form using integers. (1 point)
Final answer:
To convert y = -3/4x - 6 to standard form with integers, multiply by 4 to remove the fraction and then arrange the equation as 3x + 4y = -24.
Explanation:
To write the equation y = -3/4x - 6 in standard form using integers, we need to rearrange the terms so that the x and y terms are on the left side of the equation and the constant is on the right side. Moreover, in standard form, the coefficients should be integers. The standard form is typically expressed as Ax + By = C.
Starting with the given equation:
y = -3/4x - 6
Multiply each term by 4 to remove the fraction:
4y = -3x - 24
Now, we need to move the x term to the left side of the equation:
3x + 4y = -24
This is the standard form of the equation, and all the coefficients are integers.
the perimeter of a rectangle of a rectangular field is 76 ft. The length is 12 ft longer than the width. Find the fields dimensions
Answer:
The length is 25 and the width is 13. (25,13)
Step-by-step explanation:
the formula for perimeter is l+l+w+w=76 or 2l+2w=76
and since we know that the length is 12 more than the width, we can create an equation. w+12=l (-l+w=-12)
solve with elimination method:
2l+2w=76
2(-l+w=-12)
2l+2w=76
-2l+2w=-24
4w=52
w=13
Now that we know w=13, add 12 to the width and you get your width (25)
You can check this with the formula 2l+2w=76
2(25)+2(13)=76
50+26=76
and
w+12=l
13+12=25
Hope this helps!
The dimensions of the field will be 13 ft and 25ft.
The perimeter of a rectangle is given as: = 2l + 2w
Length = w + 12Width = wTherefore, the perimeter will be:
2(w + 12) + 2w = 76
2w + 24 + 2w = 76
4w = 76 - 24.
4w = 52
w = 52/4.
w = 13
Width = 13 ft
Length will be: = w + 12 = 13 + 12 = 25
Therefore, the dimensions of the field will be 13 ft and 25ft.

a: y = -5x + 17
b: x = -1/5y - 17/5
c: y = 5x - 17
d: -5x - 17
In order to express the equation 5x - y = -17 in slope-intercept form (y = mx + b), we need to solve for y. After rearranging, it turns out the correct equation in slope-intercept form is y = 5x + 17.

The function h=-16t^2 +1700 gives you the height h, of an object in feet, at t seconds. How long will it take the object to hit the ground ?Round to the nearest hundresth of a second?
Answer:
The object will hit the ground after 10.308 seconds.
Step-by-step explanation:
h(t) = -16t² + 1700
If you graphed this function, the object would be shown hitting the ground when it crosses the x-axis, in other words, when h = 0. So, to find the answer, just set h(t) equal to 0 and solve.
-16t² + 1700 = 0 Plug this into a calculator if you have one.
t = -10.308 and t = 10.308
Since time can't be negative, your answer will be the positive value, 10.308.
The object, described by the equation h(t) = -16t^2 + 1700, will hit the ground after around 10.308 seconds. This is determined by setting h(t) to 0, yielding a valid, positive solution.
The provided equation h(t) = -16t^2 + 1700 describes the height (h) of an object as a function of time (t), taking into account gravitational acceleration. To determine when the object hits the ground, set h(t) to 0 and solve for t:
-16t^2 + 1700 = 0
Solving this equation using the quadratic formula or factoring yields two solutions: t = -10.308 and t = 10.308. However, time cannot be negative in this context, so the only valid solution is t = 10.308.
Consequently, the object will hit the ground after approximately 10.308 seconds. This conclusion is reached by identifying the point where the height function intersects the x-axis, representing ground level. The positive value for t ensures a meaningful interpretation in the temporal context, indicating the time elapsed until the object reaches the ground.

Jayla buys and sells vintage clothing. She bought 2 blouses for $25 each and later sold them for $38 each. She bought 3 skirts for $15 each and later sold them for $26 each. She bought 5 pairs of pants for $30 each and later sold them for $65 each. Jayla's expenses for purchasing each items were: Her revenue: Total profit:
Answer:
Expenses for purchasing is $245 ,Revenue $479 and Total profit $ 234
Step-by-step explanation:
Cost of two blouses = 2× 25 = $50
Revenue from blouses = 2× 38 = $76
Profit of blouses = 76- 50 = $26
Similarly cost of 3 skirts = 3×15 = $45
Revenue from Skirts = 3×26 =$78
Profit from skirts = 78-45 =$33
Now cost price of pants = 5×30 =$150
Revenue from Pants = 5×65 =$325
Profit from pants = 325-150 = $175
So Jayla's expenses for purchasing = 50+45+150
= $245
Revenue = 76+78+325
= $479
Total Profit = 479 -245
= $234
Jayla's total expenses were $245, she made $479 in revenue through sales, making her resultant profit $234. This is calculated by subtracting the total expenses from the total revenue.
Explanation:The subject of this problem deals with the concepts of expenses, revenues, and profit in a small business setting. Jayla spent $50 on the blouses (2 x $25), $45 on the skirts (3 x $15), and $150 on the pants (5 x $30), adding up to a total expense of $245. She sold these items for total revenues of $76 for the blouses (2 x $38), $78 for the skirts (3 x $26), and $325 for the pants (5 x $65), giving her a total revenue of $479. The total profit can be calculated by subtracting the total expenses from the total revenue, and therefore, Jayla made a profit of $234 ($479 - $245).
