-18 + x = -11
Let's add 18 to both sides
x = 7
Answer:
see explanation
Step-by-step explanation:
Given the translation rule
(x, y ) → (x + 3, y - 2 )
This means add 3 to the original x- coordinate and subtract 2 from the original y- coordinate, thus
A(0, 2 ) → A'(0 + 3, 2 - 2 ) → A'(3, 0 )
B(- 2, - 5 ) → B'(- 2 + 3, - 5 - 2 ) → B'(1, - 7 )
C(0, 5 ) → C'(0 + 3, 5 - 2 ) → C'(3, 3 )
This is true.
Example:
= 8/9 ÷ 7/3
to divide fractions, multiply by the reciprocal/inverse of 7/3
= 8/9 * 3/7
= (8*3)/(9*7)
multiply numerators; multiply denominators
= 24/63
simplify
= 8/21
ANSWER: This is (A) true
