Answer:
(x, y) = (5, 4)
Step-by-step explanation:
Subtracting the second equation from the first eliminates the x term.
(4x +6y) -(4x +2y) = (44) -(28)
4y = 16 . . . . simplify
y = 4
Using the second equation to find x, we have ...
4x +2(4) = 28
x + 2 = 7 . . . . . . divide by 4
x = 5 . . . . . . . . . subtract 2
The solution is (x, y) = (5, 4).

The solution for b could really be any answers as long as when that number is divided by 4.3 it is less than 11.3
1 possible answer though could be 11.3
Because when 11.3 is divided by 4.3 it is less then 11.3

i just did 4 times 4 and add it to 8 times 2
Answer:
The area of the figure is 28.
Step-by-step explanation:
First, split it into a square and a trapezoid.
Then calculate the area of each of them.
Square = 4 times 4 = 16
Trapezoid = ((4 + 2)/ 2)*4 = 12
12 + 16 = 28

If a single person earns 33,200 what would his taxes be to the nearest dollar
Answer: The answer is,
$5,110
Option (B)
The tax of a single person that earns $33,200 is $5110
The earnings (E) is given as:
[tex]E = \$33,200[/tex]
From the tax table, the equation to calculate the tax of a single person within the income range $28400 to $68,799.99 is:
[tex]Tax =0.25E - 3190[/tex]
So, we have:
[tex]Tax =0.25 \times 33200 - 3190[/tex]
[tex]Tax =8300 - 3190[/tex]
Evaluate the like terms
[tex]Tax =5110[/tex]
Hence, the tax of a single person that earns $33,200 is $5110

This cylinder is 7 inches tall and has a volume of 63pi in3. what is the area of the cross section
Answer:
area of cross section of cylinder is inch²
Step-by-step explanation:
Given : Cylinder is 7 inch tall and has a volume of inches³.
We have to find the area of cross section of cylinder.
Area of cross section of cylinder =
To find the cross section first find radius.
Given Volume of cylinder = inches³
Also , Volume of cylinder =
Thus,
Divide both side by 7, we get,
On simplifying , we get,
Since, radius has to be positive, thus neglecting negative term.
Thus, radius of cylinder = 3 inch
Thus, area of cross section of cylinder =
area of cross section of cylinder =
Thus, area of cross section of cylinder is inch²

a cube has a lateral surface area of 64sq m find the total surface area of the cube
Answer:
384 square meters.
Step-by-step explanation:
Given that a cube has a lateral surface area of 64 square meters, to find the total surface area of the cube, the following calculation must be performed, knowing that the formula to calculate the area of a cube is to multiply by 6 (the number of sides of the cube) the area of one of its sides:
A x 6 = X
64 x 6 = X
384 = X
Thus, the area of the cube is 384 square meters.
two actions that are inverses of each other and explain how one action "undoes" the other.
Answer:
jayfeather friend me
Step-by-step explanation:
The inverse functions “undo” each other, You can use composition of functions to verify that 2 functions are inverses. When you compose two inverses… the result is the input value of x. 3 3 g x x = Because f(g(x)) = g(f(x)) = x, they are inverses.

What is the equation?
Answer:
y=-2+4
Step-by-step explanation:
we know the y intercept is four, so we can plug that into y=mx+b
so far we know y=mx+4
and the equation for finding slope is [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
so let's find two points on the graph
let's make it easy on ourselves and use the points laid out for us
(0,4) and (2,0)
[tex]\frac{0-4}{2-0}[/tex]
solving that would come out to be [tex]\frac{-4}{2}[/tex]
simplified, that would be -2
now that we know the slope, we can put them into slope-intercept form
y=-2+4

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.

The circumference of a circle is 7xm.
What is the area of the circle?
A. 3.57x m²
B. 12.257x m2
C. 147xm2
D. 497xm2
Answer:
A = 3.57 m²
Step-by-step explanation:
Given that,
The circumference of a circle is 7xm.
The expression for the circumference of a circle is given by :
[tex]C=2\pi r[/tex]
r is the radius of the circle
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{7}{2\times \dfrac{22}{7}}\\\\r=1.11\ m[/tex]
The area of a circle is given by :
[tex]A=\pi r^2\\\\A=3.14\times (1.11)^2\\\\A=3.89\ m^2[/tex]
Out of given option,
A = 3.57 m²
So, the area of the circle is 3.57 m².
