Answer:
y =1/2x+6
y = -2x+2
Step-by-step explanation:
Perpendicular line have slopes that multiply to -1
The slopes are negative reciprocals
-4*4 = 16 not perpendicular
1/2 * -2 = -1 perpendicular
1/5 *5 = 1 not perpendicular
2/3 * 2/3 = 4/9 not perpendicular
(f · g)(x) = f(x) · g(x)
f(x) = 3x + 2; g(x) = x^2 + 1
(f · g)(x) = (3x + 2)(x^2 + 1) = 3x^3 + 3x + 2x^2 + 2 = 3x^3 + 2x^2 + 3x + 2
Bruce should be glad he has parents to buy him stickers. Unless his last name is Wayne, then maybe Alfred is buying them for him... But what does stickers have to do with pencils? By the way, Alex has 45 pencils.
