Step-by-step explanation:
Answer:
Option A) y = -2x + 15
Step-by-step explanation:
step 1
Find the slope of the line perpendicular to the given line
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
The equation of the given line is

so
The slope of the given line is 
therefore
The slope of the line perpendicular to the given line is

step 2
Find the equation of the perpendicular line in point slope form

we have


substitute
---> equation in point slope form
Convert to slope intercept form




Answer:
32
Step-by-step explanation:
I mutiplied 2 to the 5th power and it equals 32
GCF(9; 15) = 3
9 = 3 · 3
15 = 3 · 5
9 + 15 = 3 · 3 + 3 · 5 = 3·(3 + 5)
Used distributive property: a(b + c) = ab + ac
