Answer:
A. (−3,5)
Step-by-step explanation:
The rule for dilation by scale factor k is given by:
The given point is P(-3,5) and the scale factor is k=1
We substitute the point and the scale factor into the rule to get:
This gives us:
The correct answer is A
8) red and 1, red and 2, red and 3, blue and 1, blue and 2, blue and 3

9) 0.5*1/3 = 0.17
10) 0.5*2/3 = 0.33
Answer:
x = ±
Step-by-step explanation:
Given
ln(x² - 16) = 0, then
x² - 16 = = 1 ( add 16 to both sides )
x² = 17 ( take the square root of both sides )
x = ±
Step-by-step explanation:
Factor by grouping.
f(x) = x³ + 3x² − 5x − 4
f(x) = x³ + 3x² − 4x − x − 4
f(x) = x (x² + 3x − 4) − (x + 4)
f(x) = x (x − 1) (x + 4) − (x + 4)
f(x) = (x² − x) (x + 4) − (x + 4)
f(x) = (x² − x − 1) (x + 4)
