O det(A) = (-3)(-6) – (1)(6)
O det(A) = (-3)(-6) + (1)(6)
O det(A) = (1)(6)-(-3)(-6)
O det(A) = (-3)(-6) + (-1)(-6)

step-by-step explanation:

x/3-10=8

x/3=18

x=48

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
