Is PQRST a scaled copy of ABCDE? Explain your reasoning. HELP PLEASE
Answers
Answer:
No.
Step-by-step explanation:
For polygon PQRST to be considered a scaled copy of polygon ABCDE, it means every segments of polygon ABCDE were increased proportionally by a scale factor.
The segments in polygon PQRST were not gotten using the same scale factor, hence, it is not a scaled copy of the original polygon, ABCDE.
Segment CD = 2 units, it corresponds to segment RS = 4 units. Scale factor = RS/CD = 4/2 = 2
Segment BC = 1 unit, it corresponds to segment QR = 1 unit. Scale factor = QR/BC = 1/1 = 1 units.
Varying scale factor shows polygon PQRST is not a scaled copy of polygon ABCDE.

When you calculate your net worth and file your taxes, good _______ is particularly important.
A. insurance
B. credit management
C. record keeping
D. communication
Answers
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.

step two: since they are all adding the constants to the variable. add the constants together.
step three: set up your equation.
your equation should be: 9x+22=180
step four: get rid of the constant (22) by doing the opposite of operation (subtraction or addition) that is being used. once you do that do the operation you choose to get rid of the 22 with do it to the total.
it should look like the picture.
step five: to get rid of the coefficient do the opposite of the operation which in this case are multiplying. so by dividing by 9 you get rid of the 9 next to the x and once you divide the 158 by 9 the quotient is the valve of the x.
step six: now multiply the valve of x by 9 and add the 22. then subtract what you get with 180.
now you have your answer

If PR=40, what are PQ and RQ
Answers
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

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]7x-20=6x-10[/tex]
Add 20 to both sides:

solve for x: x-17 =-29
Answers
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.
X+ 3y = 9
2x+ y = -2
Solve for x and y
Answers
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 >

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).
