(Please this is URGENT!) On a computer screen, Jennifer just created a triangular design of a banner with vertices at A(-4,3), B(-1,5) and C(-1,2). She can use the computer software to perform transformations on this design.
Which sequence of two transformations could she perform so that the transformed vertices become A'(4,-5), B'(7,-7), and C'(7,-4)?
a. translating 6 units down, followed by translating 8 units to the right
b. reflecting about the line y = -2, followed by translating 8 units to the right
c. reflecting about the line y = -1, followed by reflecting about the y-axis
d. reflecting about the line y = -1, followed by translating 8 units to the right
Answer:
The answer is D
Step-by-step explanation:
Transformation involves changing the position of points in the coordinate plane
The sequence of two transformations is (d) reflecting about the line y = -1, followed by translating 8 units to the right
The vertices of ABC are given as
[tex]A = (-4,3)[/tex]
[tex]B = (-1,5)[/tex]
[tex]C = (-1,2)[/tex]
First the vertices of ABC are reflected across the line y = -1.
The rule of this transformation is:
[tex](x,y) \to (x,-2-y)[/tex]
So, the vertices of ABC after reflection across the line y = -1 are
[tex]A = (-4,-5)[/tex]
[tex]B = (-1,-7)[/tex]
[tex]C = (-1,-4)[/tex]
Next, the vertices are shifted 8 units right.
The rule of this transformation is:
[tex](x,y) \to (x + 8,y)[/tex]
So, the vertices of ABC after this horizontal shift are
[tex]A' = (-4 + 8,-5)[/tex]
[tex]A' = (4,-5)[/tex]
[tex]B' = (-1 + 8,-7)[/tex]
[tex]B' = (7,-7)[/tex]
[tex]C' = (-1 + 8,-4)[/tex]
[tex]C' = (7,-4)[/tex]
Hence, the sequence of transformation is (d)

What is the product of 7.8 and 2 in expanded form?
Answer:
Step-by-step explanation:
So multiply 7.8 and 2 first, then you have the answer, then try to find the expanded form that's it lol
7.8 x 2 = 15.6
that's fifteen and six tenths
that's 15 + 0.6
if you need a better answer i'm sorry i tried TwT
The product of 7.8 and 2 is 10 + 5 + 0.6 which equates to one ten, one five, and six-tenths in expanded form.
How do you write in expanded form?The expanded form divides the number and expresses it in units, tens, hundreds, and thousands of different forms. The expanded form of the number 1632, for example, is 1000+600+30+2. There are 5 hundred, 8 tens, and 2 ones in the number 582.
We have to determine the product of 7.8 and 2 in expanded form
The numbers are given in the question :
7.8 and 2
We have to multiply 7.8 and 2 first, then attempt to get the extended form,
⇒ 7.8 × 2
⇒ 15.6
⇒ 15 + 0.6
⇒ 10 + 5 + 0.6
Here it equates to one ten, one five, and six tenths
Therefore, the product of 7.8 and 2 is 10 + 5 + 0.6 which equates to one ten, one five, and six-tenths in expanded form.

The statements that are true about congruent triangles :
I. Each of the three pairs of corresponding sides are of equal length.
II. Each of the three pairs of corresponding angles are of equal measure.
What are congruent triangles?"Two triangles are congruent if and only if it obeys following two conditions.
- three corresponding sides are equal
- all the three corresponding angles are equal in measure"
For given example,
Consider two triangles ABC and PQR.
If i) ∠A = ∠P, ∠B = ∠Q, ∠C = ∠R
ii) Also, AB = PQ, BC = QR and AC = PR
then ΔABC and ΔPQR are congruent triangles and it is written as ΔABC ≅ ΔPQR
Therefore, the statements that are true about congruent triangles :
I. Each of the three pairs of corresponding sides are of equal length.
II. Each of the three pairs of corresponding angles are of equal measure.

is 9/10 bigger than 30/60
Answer:
Yes
Step-by-step explanation:
First, we need to put them in the same terms.
30/60... 30 is half of 60 so it can be simplified to be written as 1/2, 2/4, 4/8, or 5/10.
5/10 is smaller than 9/10
9/10 is bigger than 5/10
9/10 is bigger than 30/60
The value of y is directly proportional to the value of x. Given y = 12 when x = 36.
What is the value of y when x = 60? Show your work to receive full credit
Answer:
y = 20
Step-by-step explanation:
The problem states that y = 12 when x = 36. 36/12 is 3. This means that y is a third of what x is. This would mean that if x = 60, y would be a third of 60 which is 20 since 60/3 is 20.

The compounded ratio of two ratios [tex]a\div b[/tex] and [tex]c\div d[/tex] is defined as [tex]ac\div bd[/tex].
So, in your case, we have
[tex]\dfrac{7\cdot 8}{5x}=\dfrac{83}{60}[/tex]
Solving for [tex]x[/tex] yields
[tex]x=\dfrac{56\cdot 60}{5\cdot 83}=\dfrac{672}{83}[/tex]
two fifth of the worker in a factory are men. the rest are women .if there are 28 men, how many more women than men are there?
Answer:
42 women
Step-by-step explanation:
if 28 people are men, and 2/5 of the workers are men, then there are 14 men that work there. so 1/5 = 14
x = 14
2/5 = 2x = 28
3/5 = 3x = 42
