Denise proposes the following transformation rule for this rotation:
(x,y) ➝ (y+4, -x-2)
Does this rule work? Justify your answer.
Answers
Answer:
The proposed rule correctly works.
Step-by-step explanation:
As the original triangle has the vertices with the coordinates
A(-6, 6)B(-6, 1)C(-2, 1)From the given diagram, the image of the triangle has the vertices
A'(10, 4)
B'(5, 4)
C'(5, 0)
According to the proposed rule, the image should have the following vertices.
(x,y) ➝ (y+4, -x-2)
A(-6, 6) ➝ (6+4, -(-6)-2) = A'(10, 4)
B(-6, 1) ➝ (1+4, -(-6)-2) = B'(5, 4)
C(-2, 1) ➝ (1+4, -(-2)-2) = C'(5, 0)
So, the coordinates of the image of the triangle are correctly drawn as per the proposed rule.
Therefore, the proposed rule correctly works.

Divide $200 in the ratio 3:2. What is the result?
a. $140 : $60
b. $120 $80
c. $80: $120
d. $300 : $200
Answers
Answer:
b) $120 , $ 80
Step-by-step explanation:
Ratio = 3 :2
Total = 3 + 2 = 5
3/5 of 200 = [tex]\frac{3}{5}*200[/tex]
= 3 * 40
= $ 120
2/5 of 200 = [tex]\frac{2}{5}*200[/tex]
= 2 * 40
= $ 80
You are shopping for a new computer monitor. It is regularly priced at $200 but it is now on sale for 25% off. After the sale discount is applied, you can also use your 20% off coupon. What is the final price?
a. 110
b. 120
c. 130
d. 140
Answers
Answer:
b=120
Step-by-step explanation:
Using proportions, it is found that the final price of the new computer monitor is given by:
b. 120
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
It is regularly priced at $200 but it is now on sale for 25% off, hence 75% of $200 is paid, so:
P1 = 0.75 x 200 = 150.
You can also use your 20% off coupon, hence the final price is of 80% of $150, then:
FP = 0.8 x 150 = $120.
Which means that option B is correct.

Answers
Answer:
2ft
Step-by-step explanation:
Given parameters:
Area of the rectangle = [tex]1\frac{2}{3}[/tex]ft²
Width of the rectangle = [tex]\frac{5}{6}[/tex]ft
Unknown:
Length of the rectangle = ?
Solution:
The area of a rectangle is given as:
Area of rectangle = length x breadth
Now insert the parameters and solve for length
[tex]\frac{5}{3}[/tex] = L x [tex]\frac{5}{6}[/tex]
L = [tex]\frac{5}{3}[/tex] x [tex]\frac{6}{5}[/tex] = 2ft

It’s saying product of a number and 4 so we would multiply 4 and a variable (I chose n) then it says nine more than that so you would add that to 4n then it equals 7.
Answer:
equation is 9+(4x) = 7
x = -0.5
Step-by-step explanation:

to prove:
9+(-0.5*4) = 7
9 + -2 = 7
7 = 7

During a flu epidemic the number of sick people triples every week what is the growth rate as a percent ?
Answers
Answer:
2 or 200%
Step-by-step explanation:If the growth rate doubled every week, it would grow by 100% per week. Since the growth rate triples every week, it grows by 200% per week. This is easy to see..... If 1 person is sick at the start.......by the end of the first week, 2 more would be sick. And 2 is 200% of 1. So, 3 people are sick at the end of the first week- triple that of the start. At the end of the second week, 6 more would be sick , and 6 is 200% of 3. So, 9 people total are sick at the end of the second week - triple that of the beginning of the second week

If the area of a circle is 324 cm, find:

Answer:
20.3π cm
Step-by-step explanation:
Area of a circle = 324 square cm
πr² = 324
[tex]\frac{22}{7}*r^{2}= 324\\\\ r^{2} = \frac{324*7}{22}\\\\ r^{2}= 103.09\\\\ r =\sqrt{103.09}\\\\[/tex]
r = 10.15 cm
Circumference = 2πr
