For Marvin used the Quantitative Reasoning Process to build a budget while he is going to college. He worked hard over the summer and saved $2,595.9 to live on during the next two semesters of school. Marvin will receive a scholarship each semester for $958.35 money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items is mathematically given as
$4512.6
How much money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items?Savings with Marvin = $2,595.9
Scholarship amount = $958.35
Total Scholarship amount received in 2 semesters = $958.35 X 2 = $ 1916.7
Now total money that Paolo have = (Savings with Marvin) + (Total Scholarship amount received in both semesters) = $2,595.9 + $1916.7 = $ 4512.6
Tuition & books cost = $2000
Tuition & books cost for 2 semesters = $2000 X 2 = $4000
Housing cost for 2 semester contract =$1,000
Total expenses in books and housing = $4000+ $1000 = $5000
Money left with Marvin after Total expenses in books and housing = $ 4512.6 - $5000 = −487.4
This means he has overspent.
as no. of months in 2 semesters = 8
Amount that Marvin would be in debt each month = −487.4/8 = −$60.925

evaluate the expression when a= -7 and b=4 for 3b-a
Step-by-step explanation:
By putting value of a and b in 3b-a
The value of the expression 3b - a is 19 when a= -7 and b=4 the answer is 19.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an expression:
= 3b - a
Plug a = -7 and b = 4
= 3(4) - (-7)
= 12+7

What is his economic order quantity in units ? A ) 100 B ) 200 C ) 60 D 120
Mark Achin's economic order quantity in units is D. 120 units.
What is economic order quantity?The economic order quantity (EOQ) is the optimal order quantity that minimizes the total costs (ordering, receiving, and holding inventory).
The formula for the economic order quantity is the square root of [2(setup costs)(demand rate)] / holding costs.
Data and Calculations:Annual demand = 3,600
Cost price per unit = $200
Ordering cost = $40
Holding cost per unit = $20
Working days per year = 360
Lead time = 5 days
Economic order quantity (EOQ) = square root of: [2(setup costs)(demand rate)] / holding costs.
= square root of (2 x $40 x 3,600)/$20
= 120
Thus, Mark Achin's economic order quantity in units is D. 120 units.

f(x)=3√x + 7. Find the inverse of f(x).
Answer:
[tex]f^{-1}(x)=\left(\dfrac{x-7}{3}\right)^2[/tex]
Step-by-step explanation:
Given function:
[tex]f(x)=3\sqrt{x}+7[/tex]
To find the inverse of the function
Swap f(x) for y:
[tex]\implies y=3 \sqrt{x}+7[/tex]
Subtract 7 from both sides:
[tex]\implies y-7=3 \sqrt{x}+7-7[/tex]
[tex]\implies y-7=3\sqrt{x}[/tex]
Divide both sides by 3:
[tex]\implies \dfrac{3\sqrt{x}}{3}=\dfrac{y-7}{3}[/tex]
[tex]\implies \sqrt{x}=\dfrac{y-7}{3}[/tex]
Square both sides:
[tex]\implies \left(\sqrt{x}\right)^2=\left(\dfrac{y-7}{3}\right)^2[/tex]
[tex]\implies x=\left(\dfrac{y-7}{3}\right)^2[/tex]
Swap the x for [tex]f^{-1}(x)[/tex] and y for x:
[tex]\implies f^{-1}(x)=\left(\dfrac{x-7}{3}\right)^2[/tex]
Linda needs to buy pencils brands has a pack of 28 pencils for 5.29 brand b has a pack of 48 pencils for 8.47 find the unit price for each brand.
Answer:
Brand A is the best buy.
Step-by-step explanation:
Brand A has a pack of 28 pencils for 5.29 dollars. This means that the unit cost of one pencil in Brand A would be 5.29/28 = 0.2$ per pencil rounded up to the nearest tenth.Brand B has a pack of 48 pencils for 8.47 dollars. This means that the unit cost of one pencil in Brand B would be 8.47/48 = $0.8 per pencil rounded up to the nearest tenth.Since $0.2 is lesser than $0.8, it means that Brand A is the best buy.

Which function is the inverse of if the domain of f(x) is x ≥ 0?
The question was incomplete. Please find full content below.
Which function is the inverse of
[tex]f(x)=x^2-16[/tex]
if the domain of f(x) is x ≥ 0?
The inverse funtion of the given function is given by
[tex]\mathbf{f(x)=\sqrt{x+16}}[/tex]
where the domain is x ≥ -16.
Given the function is,
[tex]f(x) =x^2-16[/tex]
Let, y = f(x)
[tex]y = x^2-16[/tex]
Adding 16 to both sides we get,
[tex]y + 16 = {x}^{2} - 16 + 16[/tex]
[tex] {x}^{2} = y + 16[/tex]
Now, square rooting to both sides we get, since x ≥ 0
[tex]\sqrt{x^2}=\sqrt{y+16}[/tex]
[tex]x=\sqrt{y+16}[/tex]
[tex]f^{-1}(y)=\sqrt{y+16}[/tex]
Hence substituting x in place of y,
[tex]f^{-1}(x)=\sqrt{x+16}[/tex]
Above function is the required inverse function where the domain of that is given by, x ≥ -16.

Answer:
B) y = 4/5x - 2
Answer:
B
Step-by-step explanation:
First, we can find the slope of the graph.
The distance of x between the two points is 5, and the distance of y between the two points is 4.
The slope formula is (Increase in y)/(increase in x)
So the slope will be 4/5.
The y-intercept is (0,-2), so the number at the very end of the equation will be -2.
With all this in mind, we can be sure that our answer is B: y=4/5x-2

Which point corresponds to the real zero of the graph of y = log2 (x + 2) - 1?
Answer:
(0, 0)
Step-by-step explanation:
Ok so you have the equation: [tex]y = log_2{(x+2)}-1[/tex]. To find the zero you simply set the y equal to zero and then solve for x
[tex]0 = log_2{(x+2)}-1[/tex]
Add 1 to both sides
[tex]1 = log_2{x+2}[/tex]
Rewrite the equation in exponential form:

Subtract 2 from both sides
[tex]0 = x[/tex]
So the zero of the function is at the origin (0, 0)

During a week in which the company has budgeted $1,600 for materials and $2,700 for labor, how many mountain bikes does the company plan to manufacture?
An equation is formed when two equal expressions. The company is planning to produce 25 mountain bikes and 15 trail bikes.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of mountain bikes produced by the company be x, while the number of trail bikes produced by the company is y.
The cost of materials for a mountain bike is $40, and the cost of materials for a trail bike is $40. Also, the budget of the company is $1,600. Therefore,
1600 = 40x + 40y
x + y = 40
y = 40-x
The cost of labour to manufacture a mountain bike is $90, and the cost of labour to manufacture a trail bike is $30. Also, the budget for labour is $2,700.
2700 = 90x + 30y
2700 = 90x + 30(40-x)
2700 = 90x + 1200 - 30x
1500 = 60x
x = 25
Substitute the value of x,
y = 40 - x
y = 15
Hence, the company is planning to produce 25 mountain bikes and 15 trail bikes.
