Answer:
Step-by-step explanation:
so the g(x) = x-1 gets plugged into every x in the f(x) function
=
- 3(x-1) + 3
=
-2x+1 -3x +3 + 3
= -5x +7
now plug in x = 5
=
-5(5) +7
= 7
Base times height divided by 2
Answer:
1/8
Step-by-step explanation:
Given:
- 2 blue pens
- 2 black pens
- 4 red pens
=> the total pens: 2+2+4 = 8
The probability of taking out a red pen is: 4/8
Because the is replacement when you put the red back in the box and the sum of pen is unchanged.
So the probability of taking out a blue pen is: 2/8
So the probability of taking out a red pen followed by the blue pen is:
4/8 * 2/8 = 1/8
Hope it will find you well.
