Two companies have sent representatives to an industry conference. Only 18 will be given the chance to make presentations. The first company sent 13 representatives, and will get to have exactly 10 presenters;
The second company sent 12 representatives, and will get to have exactly 8 presenters.
Use the template below to show the notation for calculating the number of possible combinations without repetition for 18 presenters.

5.25 ounces

step-by-step explanation:

divided 3/4 and 6

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)

answer: x=3 and y=4

step-by-step explanation:

d. you cannot tell because there are no values shown.
