Hi there!
Work out the parenthesis.
Combine like terms.
Subtract 9 from both sides.
Subtract 4x from both sides
Divide both sides by -9
<h3>Answer: D) center E, scale factor 1/4</h3>
======================================
Explanation:
Point E is the center of the dilation (we can think of this as the origin point). This is because point E is in the same exact location as point E'. This is a fixed point. The other points move.
To find the scale factor, divide E'F' over EF
scale factor = (E'F')/(EF)
scale factor = 2/8
scale factor = 1/4
Keep in mind that EF = EF'+F'F = 2+6 = 8.
Answer:
D
Step-by-step explanation:
Note there is a common difference d between consecutive terms in the sequence, that is
d = 2 - 5 = - 1 - 2 = - 4 - (- 1) = - 3
This indicates that the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = - 3, thus
= 5 - 3(39) = 5 - 117 = - 112 → D
