PLEASE EXPLAIN HOW TO DO THIS!! I COMPLETELY FORGOT ☠️-

A bag contains 86 marbles, some of which are black and some of which are white. If the probability of selecting a black marble is 33/43 find:

A) The number of black marbles

B) The number of white marbles

true !

step-by-step explanation:

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)

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
