k = -3

Step-by-step explanation:

Let's rewrite the equations in their slope-intercept forms:

y = \frac{1}{3}x + 2\:\:\:\:\:\:\:(1)

y = kx + 12\:\:\:\:\:(2)

In order for Eqn(2) to be perpendicular to Eqn(1), the slope of Eqn(2) must be the negative reciprocal of that of Eqn(1). Therefore, k = -3.

bezimeni [28]
Area= legnth times width
or sometimes
area=legnth times height
area=measure1 times measure 2 on a flat plane
dependson the names

area=27
height=6
area=legnth times height
subsitute
27=legnth times 6
divide both sides by 6
27/6= legnth
simplified to 4 and 3/4
