y = - 3(x + 1 )² + 2
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here vertex = (- 1, 2), hence
y = a(x + 1)² + 2
to find a substitute (1, - 10) into the equation
- 10 = 4a + 2 ⇒ 4a = - 12 ⇒ a = - 3
y = - 3(x + 1)² + 2 ← in vertex form
Let x = number of lines
x/3 = r2 2,5,8,11,14,17,20,23,26,29,32,35,38,41,44,47
x/5 = r2 2,7,12,17,22,27,32,37,42,47
x/7 = r5 5,12,19,26,33,40,47
47 is the smallest number that fits all 3 requirements.

Step-by-step explanation:
The scale factor is the ratio of corresponding sides, image to original, that is
= =
Answer:
%
Step-by-step explanation:
you multiply 2 because you want to get from 50 to 100 and you need to multiply 2 to do that
