Is it a multiple choice question
F(-1) = 2(-1)^2 + 8(-1)
= 2(1) + (-8)
= -6
10x -15y=45
9x+15y= 12
19x= 57
x= 3
3(3)+5y= 4
9 + 5y = 4
5y = -5
y = -1
(3,-1)
Answer:
there are 12 picks
There is 2 2's
There is one 4 and two 8's
2/12 x 3/12 = 6/144 = 1/24
2 chances of getting wanted number/ 12 amount of outcomes
1/24 is correct
Step-by-step explanation:
To find the inverse function, switch the two terms and solve for y again. x=-4y+1.
x-1= -4y. -(x-1)/4 = y
