remember that local minimuns are points in which the function was decreasing and starts increasing.
you can try two ways of doing it, graphing the functions or using derivatives.
since this are twelve functios the easier way is to graph them.
start by function y=x
in this case this function is continously increasing as x increases, which means that it does not have any local maxima or minima.
now do the same for
this graph has a local minima on th
Answer:
1. x=−2/3 y+2
2. x=−y+4
Step-by-step explanation:
1. 9x+6y=18
Step 1: Add -6y to both sides.
9x+6y+−6y=18+−6y
9x=−6y+18
Step 2: Divide both sides by 9.
9x/9=−6y+18/9
2. −6x−6y=−24
Step 1: Add 6y to both sides.
−6x−6y+6y=−24+6y
−6x=6y−24
Step 2: Divide both sides by -6.
−6x/−6 =6y−24/−6
Step-by-step explanation:
No of blue marbles = 7
No of green marbles = 4
No of red marbles = 6
No of yellow marbles = 8
Total marbles = 25
Probability of green marble = 4/ 25
