20 ! i need an answer now! what is the equation of a line that passes through the the point (4,2) and is perpendicular to the line whose equation is y=x/3 -1? hurry!

perpendicular means the slope is the negative reciprocal

1/3 becomes -3

point slope form

y-y1 = m(x-x1)

y-2 = -3(x-4)

change it to slope intercept form

distribute

y-2 = -3x +12

add 2 to each side

y=-3x+14

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?
