Answer: (-13xy) + (-5xy) = -18xy
Step-by-step explanation:
well they are both negatives t=so they cant be subtracted from each other instead they are being added
13 + 5= 18
but remeber to add back the negative sign adn the variables
so its -18xy

Answer:
9 cans of soup and the 4 frozen dinners were purchased
Step-by-step explanation:
Let x represent the number of cans of soup purchased.
Let y represent the number of frozen dinners purchased.
Lincoln purchased a total of 13 cans of soup and frozen dinners. This means that
x + y = 13
Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium. The 13 cans of soup and frozen dinners which he purchased collectively contain 4450 mg of sodium. This means that
250x + 550y = 4450 - - - - - - - - -1
Substituting x = 13 - y into equation 1, it becomes
250(13 - y) + 550y = 4450
3250 - 250y + 550y = 4450
- 250y + 550y = 4450 - 3250
300y = 1200
y = 1200/300
y = 4
Substituting y = 4 into x = 13 - y, it becomes
x = 13 - 4 = 9

Answer:
B
Step-by-step explanation:
Refer to the Behavioral Research in Accounting (January 2008) study of Machiavellian traits in accountants, Exercise 1.6 (p. 6). Recall that a questionnaire was administered to a random sample of 700 account- ing alumni of a large southwestern university; how- ever, due to nonresponse and incomplete answers, only 198 questionnaires could be analyzed. Based on this information, the researchers concluded that Machiavellian behavior is not required to achieve success in the accounting profession. (a) What is the population of interest to the researcher? (b) Identify the sample. (c) What inference was made by the researcher? (d) How might the nonresponses impact the inference?
Answer:
Behavioral Research in Accounting (January 2008) study of Machiavellian traits in accountants
a) Population of interest to the researcher: accountants
b) Sample = 700 accounting alumni
c) The inference made by the researcher = Machiavellian behavior is not required to achieve success in the accounting profession.
d) The non-responses reduce the sample size and this might introduce bias to the inference made to the population.
Step-by-step explanation:
a) Data and Calculations:
Research Question = Is Machiavellian behavior is required to achieve success in the accounting profession?
Population of interest = all accountants
Sample size = 700 accounting alumni of a university
No. of analyzed questionnaires = 198
No. of questionnaires not analyzed due to nonresponse and incomplete answers = 502 (700 - 198)
Percentage of analyzed questionnaires to sample size = 28.3% (198/700 *100)
Percentage of questionnaires not analyzed = 71.7% (100% - 28.3%)
Conclusion reached by the researchers = Machiavellian behavior is not required to achieve success in the accounting profession.
20x=-58-2y
17x=-49-2y
Answer:
20x = -58 - 2y( Ans~ x= -29/11)
17x = -49 - 2y (Ans~ x = -49/19)
Step-by-step explanation:
(1) 20x = -58 2x
20x + 2x = -58
22x = -58
x = -29/11
(2) 17x = -49 - 2x
17x + 2x = -49
19x = -49
x = -49/19
U WELCOME!!
Answer:
y=1
x=-3
Step-by-step explanation:
20x=-58-2y
20x/20=(-58-2y)/20
x=(-58-2y)/20
17x=-49-2y
17x/17=(-49-2y)/17
x=(-49-2y)/17
(-58-2y)/20=(-49-2y)/17
17(-58-2y)=20(-49-2y)
-986-34y=-980-40y
add 40y to both sides
6y-986=-980
add 986 to both sides
6y=6
divide both sides by 6
y=1
substitute
20x=-58-2(1)
20x=-60
x=-3
Proof: (substituting x & y values in original equations)
20(-3)=-58-2(1)
-60=-60
17(-3)=-49-2(1)
-51=-51

For every 6 trucks there are 10 cars parked in the commuter lot. If there are 25
cars parked in the lot, how many trucks are there?
Answer:
15
Step-by-step explanation:
The ratio of trucks to cars is 6x/10. And in the problem it says that there are 25 cars. So, 10x = 25, x = 5/2. Then, 6x = 15

Step-by-step explanation:
x must equal 2 and 2 to the power of 2 is 4
Answer:
4
Step-by-step explanation:
Original equation: 3x-1=5
Add 1 on both sides: 3x=6
Divide by 3 on both sides: x=2
If x=2, then x^2 = 4.

If you deposit 4500 in an account paying 3.2% interest continually home much will the account balance be after 1.5 year
Answer:
We conclude that the total amount accrued, principal plus interest, from compound interest on an original principal of $4,500.00 at a rate of 3.2% per year compounded continuously over 1.5 years is $4,721.27.
Step-by-step explanation:
Given
Principle P = 4500 (Let say in $)Interest rate r = 3.2% = 0.032Time period t = 1.5 yearsTo determine
Accrue Amount A = ?
Using the formula
[tex]A\:=\:Pe^{rt}[/tex]
substitute r = 0.032, P = 4500, and t = 1.5
[tex]A\:=\:4,500.00\left(2.71828\right)^{\left(0.032\right)\left(1.5\right)}[/tex]
A = $ 4721.27
Therefore, we conclude that the total amount accrued, principal plus interest, from compound interest on an original principal of $4,500.00 at a rate of 3.2% per year compounded continuously over 1.5 years is $4,721.27.

Write the equation for a vertical line going through the point
(-4,1)
Answer:
x = -4
Step-by-step explanation:
a vertical line means it will cross only the x-axis, not the y-axis
wherever it cross the axis, that will be the point in your equation
example, a vertical line through the point (5, -10) has the equation x = 5
