Ayako claims that there are centers of dilations through which a dilation of line n by a factor of 1.5 leaves
Line n unchanged. Determine whether each point below represents a center of dilation that supports
Ayako's claim. Select Yes or No for each point.
Yes No
Point AOC
Point BOO
Point COO
Point DOO
Point EOC
Answers
Answer:
The points that represent a center of dilation that supports Ayako's claim are;
Point A; Yes
Point D; Yes
Step-by-step explanation:
When the figure being dilated has a segment or side that rests on the center of dilation, the corresponding side or segment of the image of the preimage of the figure will both be located on the same line
Therefore, given that the line 'n' is infinite, the centers of dilation through which a dilation of the line 'n' will form an image that will be on the same line as line 'n' are centers of dilation located on line 'n', which are;
Point A and Point D

Determine which of the transformations applied to Circle A could be used to prove Circle A is similar to Circle B. Select Yes or No for each transformations.
THE ANSWER I PUT WAS WRONG!!!
Answers
Answer:
Step-by-step explanation:
Circle A has center (-2, 3)
Circle B has center (2, -2)
Circle A can be mapped to Circle A' by a translation:
Center Rule of translation New center
(x, y) (x+4, y-5)
A(-2, 3) A'(-2+4, 3-5) A'(2, -2)
Circle A with radius r 1=2
Circle B with radius r 2=3
Scale factor= r 2/r 1 = 3/2 = 1.5
Since any two circles can be translated to have the same center, the dilation r2/r1 proves the circles are similar where r1 and r2 are the radii of the circles.
The Circle A' and circle B both have center (2, -2). Then circle A' can be mapped to circle B by a dilation with center (2, -2) and a scale factor 3/2=1.5. So circle A and circle B are similar.
Therefore: Translation right 4, down 5, and then a dilation of 1.5 is true.
Translation down 5, right 4, and then a dilation of 1.5 is true.

Answers
Janet can buy 36 sets of cutlery.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Janet has a 65 dollar budget to buy paper goods and plastic cutlery for an impromptu birthday party
the paper goods will cost 37.50
We need to find the difference of 65 dollars and 37.50 to determine the amount left to purchase cutlery
65-37.5
27.5
As by given, each cutlery set costs 0.75.
We need to divide 27.5 by 0.75 to find number of cutlery sets
27.5/0.75=36.6
Hence, Janet can buy 36 sets of cutlery.

h is the x-coordinate of the center of the circle, and k is the y-coordinate.
x and y are coordinates of a point the circumference touches.

Determine and describe the number and type of roots of the quadratic functions. Show any and all work necessary to determine your answer. Justify your answer with appropriate reasoning. a) y=3x^2+7x+8 b) y=2x^2-7x-2 c) y=9x^2+30+25
Answers
Answer:
See explanations below
Step-by-step explanation:
The root of a quadratic equation is determined by its discriminant
D = b²-4ac
If D > 0, the roots are real and unique
If D < 0, the roots are complex
If D= 0, the roots are real and equal
a) For the quadratic equation
y=3x^2+7x+8
Since the highest degree of the equation is 2, hence the equation will have 2 roots
From the equation, a = 3, b = 7 and c = 8
Get the discriminant
D = 7²-4(3)(8)
D = 49 - 96
D = -47
Since the discriminant value is less than 0, hence the roots are complex roots
b) For the quadratic equation
y=2x^2-7x-2
Since the highest degree of the equation is 2, hence the equation will have 2 roots
From the equation, a = 2, b = -3 and c = -2
Get the discriminant
D = (-3)²-4(2)(-2)
D = 9 + 16
D = 25
Since the discriminant value is greater than 0, hence the roots are real and unique.
c) For the quadratic equation
y=9x^2+30x+25
Since the highest degree of the equation is 2, hence the equation will have 2 roots
From the equation, a = 9, b = 30 and c = 25
Get the discriminant
D = 30²-4(9)(25)
D = 900 - 900
D = 0
Since the discriminant value is equal to 0, hence the roots are complex real and equal
Sylvie needs $110 for a concert ticket. She already has $16 and she can earn the rest by working 10 hours at her job. If h represents her hourly earnings, which of the following equations can be solved to find Sylvie’s hourly earnings? Select all that apply
A 110 - 16 = 10h
B 110 = 16h + 10
C 16 = 110 - h
D 110 = 16 + 10h
E 110 + 16 = 10h
Answers
Answer:
Option A and D
Hope this helps!
Answer:
D
Step-by-step explanation:
16 +10h = 110 is the equation because it uses 10h to represent the hourly wages and you need $110. Therefore, with the starting $16, if you use the hourly $10 rate you can come to your answer using the equation.
