Ms.Clark goes to the store and purchased a 26 lb turkey for $38.74 and two bags of potatoes. Her bill was $50.24. How much was each bag of potatoes? Write and solves the equations.
Answer:
$5.75
Step-by-step explanation:
50.24 - 38.74 is 11.5
Then, to find how much each potato bag is you need to divide by 2.
11.5 divided by 2 is 5.75.
Each bag of potatoes was 5.75$

8x + 4y = 12
y = -2x + 3
Please help me!
Answer:
(x,y) =(3/14,3/14)
Step-by-step explanation:
8x+ 4y=-2x+3 WRITE AS SYSTEM OFEQUATIONS
12y=-2x=3 simplify expressions
10x +4y =3
2x+12y=3 .......multiply both sides of the equation by -5
10x +4y=3
-10x -60= -15 sum both equations to eliminate a variable (10x cancels
and 3+-5 +-12
-56y= -12 divide both side by -56
y=3/14
2x+12x3/14=3 substitute the given value of y into the equation
x=3/14

Evaluate D57C-76CA in base 16
c₁₆ - a₁₆ = 12 - 10 = 2₁₆
7 < c = 12 in base 16, so borrow 1 from the next place value:
17₁₆ - c₁₆ = 23 - 12 = 11 = b₁₆
In the next place, we replace 5 with 4, but 4 < 6, so borrow 1 from the next place value again:
14₁₆ - 6₁₆ = 20 - 6 = 14 = e₁₆
Replace d with c, so that
c₁₆ - 7₁₆ = 12 - 7 = 5₁₆
and this gives
d57c₁₆ - 76ca₁₆ = 5eb2₁₆
What is the slope of the line that goes through the points (-1,4) and (14,-2)?
Answer:
hi! so we have 2 points right? you will need to use something called the slope formula y2-y1/x2-x1 we're subtracting our y values of both points and x values of both points while dividing them this gives us a slope of a line
now I want you to label before you do this in your head! it can get confusing to think about it so label label (x1-1,y1 4) (x2 14,y2 -2) now you have them labeled this parts easy! use the formula -2-4/14--1 okay now use your calculator you get -2/5 and now you have your m or slope!

6. Given the implicit curve x^2-ln(x/y)=1 , Write the linear approximation () of the tangent line at (1,1) A) L(x)=-x-2 B) L(x)= -x+2 C) L(x)= -x-1 D) L(x)= -x+1
Answer:
B) L(x) = -x + 2
Step-by-step explanation:
To find the tangent at (1,1), we differentiate x² - ln(x/y) = 1 with resect to x.
So, x² - ln(x/y) = 1
x² - (lnx - lny) = 1
x² - lnx + lny = 1
differentiating both sides with respect to x, we have
d{x² - lnx + lny]/dx = d1/dx
dx²/dx - dlnx/dx + dlny]/dx = d1/dx
2x - 1/x + 1/y(dy/dx) = 0
1/y(dy/dx) = 1/x - 2x
dy/dx = y(1/x - 2x)
dy/dx evaluated at (1,1) is
dy/dx = y(1/x - 2x)
= (1)(1/1 - 2(1))
= 1 - 2
= -1
This is the gradient of the tangent line.
To find the equation of the tangent line, we use (y - y')/(x - x') = m where y' = 1, x' = 1 and m = gradient of line = dy/dx = - 1
(y - y')/(x - x') = m
(y - y')/(x - x') = dy/dx
(y - 1)/(x - 1) = -1
cross-multiplying,
y - 1 = -1(x - 1)
expanding the bracket, we have
y - 1 = -x + 1
adding + 1 to both sides, we have
y -1 + 1 = -x + 1 + 1
y = -x + 2
So, L(x) = -x + 2
Your firm is contemplating the purchase of a new $570,000 computer-based order entry system. The system will be depreciated straight-line to zero over its five-year life. It will be worth $58,000 at the end of that time. You will save $270,000 before taxes per year in order processing costs, and you will be able to reduce working capital by $73,000 (this is a one-time reduction). If the tax rate is 35 percent, what is the IRR for this project? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.G., 32.16.)
Answer:
IRR = 31.93%
Step-by-step explanation:
Depreciation = 570,000/5 = 114,000
Calculation of Operating cash flow
Operating income = 270000 - 114000 = 156,000
Tax = 156,000 * 35% = 54,600
Operating cash flow = Operating income + Depreciation - Tax = 156,000 + 114,000 - 54,600 = 215,400
Calculation of initial investment
CF0 = Initial investment - Working capital = 570,000 - 73,000 = 497,000
Calculation of the last year cash flow
CF5 = OCF + After tax salvage - Net working capital = 215,400 + 37,000 - 73,000 = 180,100
Calculation of IRR
IRR for the project = IRR(Cashflow from year0, 1, 2,3,4,5) "as attached below picture below"
IRR for the project = 31.93%

She buys packages of 12 trading cards to add to her collection. After she adds 16 packages to her existing collection, she has a total of 274 cards.
Write a function to model the size of Sabrina’s collection.
Enter the correct equation in the box.
Answer:
x + (12x16) = 274
Step-by-step explanation:
each package = 12
16 packages
16x12= 192
x + 192 = 274
274-192=82
x = 82
The function to model the size of Sabrina’s collection is x + (12× 16) = 274.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Total cards = cards
Each package = 12
let the size of Sabrina collection be x
Then, x + (12× 16) = 274
x + 192 = 274
x = 274- 192
x= 82
Hence, the function to model the size of Sabrina’s collection is x + (12× 16) = 274.

help me factor x^2 + 9
x 2 + 9 has no (Real) factors (Unlike x 2 − 9 )
Explanation:
The most you could do with this is use the quadratic formula on
XXXX x 2 + 0 ⋅ x + 9
to get
XXXX ± 3 i
So you could factor using Complex values:
