When you calculate your net worth and file your taxes, good _______ is particularly important.
A. insurance
B. credit management
C. record keeping
D. communication
Answer: Record keeping
Step-by-step explanation:
A person's net worth is calculated as the total assets they own minus the total liabilities they owe. As such it will be very important to keep records so that you know what you own as well its value as well as what you owe as well.
Taxes are no different. The better the records you keep are, the more accurate your tax payments will be. Without proper records you could overpay taxes which would mean you lose money or you could underpay taxes which is a crime.
50 POINTS PLEASE HELP Segment JK has endpoint J(2,4) and K(6,2). You dilate the segment using a dilation centered at the origin with a scale factor of 1/2 and then reflect the image in the x-axis. What is the midpoint of the final image?
A (2, -1.5)
B (-2, 1.5)
C (2, 1.5)
D (1.5, 2)
Answer:
C.
Step-by-step explanation:
The midpoint of the final image is (2, 1.5).
What is the scale factor?Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes both two-dimension and three-dimension.
Segment JK has endpoints J(2,4) and K(6,2).
You dilate the segment using a dilation centered at the origin with a scale factor of 1/2 and then reflect the image on the x-axis.
The co-ordinate of the final image is;
[tex]\rm J' = Scale \ factor (J) = \dfrac{1}{2} (2, \ 4) = (1, \ 2)\\\\K' = Scale \ factor (K) = \dfrac{1}{2} (6, \ 2) = (3, \ 1)\\[/tex]
The midpoint of the final image is;
[tex]\rm Midpoint \ of \ J'= \left (\dfrac{1+3}{2} \right )= \left (\dfrac{4}{2} \right )=2\\\\ Midpoint \ of \ K'= \left (\dfrac{2+1}{2} \right )= \left (\dfrac{3}{2} \right )=1.5[/tex]
Hence, the midpoint of the final image is (2, 1.5).

X+ 3y = 9
2x+ y = -2
Solve for x and y
Answer:
(-3, 4)
Step-by-step explanation:
hey there,
< From the first equation, let's find x.
x + 3y = 9
x = 9-3y (I hope you understand how that works )
Next, we can substitute our equation that equals to x into the second equation.
2x + y = -2
2(9-3y) + y = -2 (I substituted "x" in "2x" with (9-3y))
Now, let's solve.
2(9-3y) + y = -2
18 - 6y + y = -2
-5y = -20
y = 4
Now that we have found what y is equal to, we can find x too. In the beginning we found that x = 9-3y so x = 9-3(4) = -3 >
Hope this helped! Feel free to ask anything else.
Rearrange 2y = 3(2+x) make x the subject
Answer:
[tex]x =\frac{(2y-6)}{3}[/tex]
Step-by-step explanation:
2y = 3(2+x) {Use distributive rule}
2y = 3*2 + 3*x
2y = 6 + 3x {Subtract 3 form both sides}
2y - 6 = 3x {Divide both sides by 3}

solve for x: x-17 =-29
Answer:
x = - 12
Step-by-step explanation:
Given
x - 17 = - 29 ( add 17 to both sides )
x = - 12
Answer:
x=12
Step-by-step explanation:
when performing x-17=-29, you first have to do the inverse of -17 in order to isolate x. Therefore, your would +17 to the left side of the equation (x-17) resulting in only the letter x being left on that side. Then you would have to add the 17 to the other side of the equation resulting in x=-29+17 which will then result in x=12.

Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m?
-7m - 8 = m - 4
-15m = -4m
-8 - 3m = 4 - m
-8 - 7m = -4 + m
m - 4 = -7m - 8
-3m - 8 = 4 - m
Answer: answers are (-7m - 8 = m -4) and m - 4 = -7m -8. Hope this helps :)
Step-by-step explanation:
The expressions equivalent to the given expressions -2m - 5m - 8 = 3 + (-7) + m are (-7m - 8 = m - 4), (-8 - 7m = -4 + m), and (m - 4 = -7m - 8).
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given expression is -2m - 5m - 8 = 3 + (-7) + m. The given expression will be solved as:-
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = -4 + m
We can also write the same equation in different ways:-
(-8 - 7m = -4 + m)
(m - 4 = -7m - 8)
Therefore, the expressions equivalent to the given expressions -2m - 5m - 8 = 3 + (-7) + m are (-7m - 8 = m - 4), (-8 - 7m = -4 + m), and (m - 4 = -7m - 8).

Find the equation of a line in standard form that passes through the point (6, -2) and is perpendicular to 3x - 5y = 10.
please answer
6n(n+4)=-18
Answer:
n = -7
Step-by-step explanation:
Add '-24' to each side of the equation.
24 + -24 + 6n = -18 + -24
Combine like terms: 24 + -24 = 0
0 + 6n = -18 + -24
6n = -18 + -24
Combine like terms: -18 + -24 = -42
6n = -42
Divide each side by '6'.
n = -7
Simplifying
n = -7

find angles EFG pleaseee
Answer:
50 degrees.
Step-by-step explanation:
Angle FGE = [tex]180-(7x+18)[/tex] because angles on a straight line add up to 180 degrees.
Angle EFG = [tex]180-38-(180-(7x+18))=6x-10[/tex] (Angles in a triangle add up to 180)
[tex]180-38-\left(-7x+162\right)=6x-10[/tex]
[tex]180-38+7x-162=6x-10[/tex]
[tex]7x-20=6x-10[/tex]
Add 20 to both sides:
[tex]7x-20+20=6x-10+20[/tex]
[tex]7x=6x+10[/tex]
Subtract 6x from both sides:
[tex]7x-6x=6x+10-6x[/tex]
[tex]x=10[/tex]
Angle [tex]EFG=6x-10=6(10)-10=60-10=50[/tex]

If PR=40, what are PQ and RQ
Answer:
PQ = 23, QR = 17
Step-by-step explanation:
PR = PQ + QR = 40
Substitute PR and QR into the equation above
40 = 5x - 2 + x + 12
Combine like terms
40 = 6x + 10
Subtract 10 from both sides
30 = 6x
Divide both sides by 6
5 = x
PQ = 5x - 2= 5(5) - 2 = 23
Remember, PR = PQ + QR
40 = 23 + QR
Subtract 23 from both sides.
17 = QR
PQ = 23
