2 answers:
Answer:
A. dilation by a scale factor of 1/3
B. translation to the left 4 units
C. translation down 3 units
Step-by-step explanation:
On a coordinate plane,
triangle A has points (3, 3), (6, 3), (6, 9).
Triangle A prime has points (negative 2, negative 1), (negative 2, negative 2), (negative 3, negative 2).
Determine all the transformations needed to transform the pre-image, A, to the image, A'.
Select all that apply, given
A=(3,3),(6,3),(6,9)
A'=(-2,-1),(-2,-2),(-3,-2) possible typo, should read
A'=(-2,0),(-2,-2),(-3,-2)
dilation by a scale factor of 1/2
dilation by a scale factor of 1/3
reflection over the x-axis
translation to the left 4 units
translation down 3 units
If the typo correction is valid, then the transformatitons are:
A. dilation by a scale factor of 1/3
B. translation to the left 4 units
C. translation down 3 units

Answer:
The number of original students desks were there in school before purchase was made is 980 .
Step-by-step explanation:
Given as :
The total number of new desks purchased including teacher and students = 295
The number of new desks purchased for students = of original students desks available
The number of new desks purchased for teachers = 50
Let The number of original students desks available before purchase = S
Now, According to question
∵ The total number of new desks purchased including teacher and students = 295
I.e The number of new desks purchased for students + The number of new desks purchased for teachers = 295
Or, of S + 50 = 295
Or, × S = 295 - 50
Or , × S = 245
∴ S = 245 × 4 = 980
So, original desks available for students = S = 980
Hence The number of original students desks were there in school before purchase was made is 980 . Answer
