Item 8 Question 1 There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than

eimsori [14]

Given:
64 total students
x = drama club students
y = yearbook club students

x = y + 10
y = 64 - x

y = 64 - x
y = 64 - (y + 10)
y = 64 - y - 10
y + y = 64 - 10
2y = 54
2y/2 = 54/2
y = 27

x = y + 10
x = 27 + 10
x = 37

To check:

x + y = 64
37 + 27 = 64
64 = 64

Write an algebraic rule to describe the translation C(5,-4) — C'(-2, 1).

SpyIntel [72]

Option C. (x,y) → (x-7,y+5) is the correct answer

Further explanation:

Given

C(5,-4) — C'(-2, 1)

We will apply each translation rule one by one to check the correct algebraic rule.

A. (x,y) → (x - 2,y+1)

C(5, -4) → (5-2, -4+1) → C'(3,-3)

B. (x,y) → (x+7,y-5)

C(5, -4) → (5+7, -4-5) → C'(12,-9)

C. (x,y) → (x-7,y+5)

C(5, -4) → (5-7, -4+5) → C'(-2,1)

Hence, option C. (x,y) → (x-7,y+5) is the correct answer
