Answer:12.8
Step-by-step explanation:
Answer:
12.8
f(x)=3x−2 so when the variable x is replace with an actual value ( − 1 ) we get f(−1)=3(−1)−2
=−3−2
=−5
fg(2) = 9 means that f(g(2)) = 9
We know that g(2) = 6
So f(6) = 9 which means that
6a - b = 9 (note 1)
And we know that g(f(1/2)) = 2
And we know that f(1/2) = 1/2(a) - b
So g(1/2(a) - b) = 2
Meaning that 1/2(a) - b + 4 = 2
So 1/2(a) - b = - 2 (note 2)
Using note 1 and 2 we can solve the equation
11/2(a) = 11 so a = 2 and b = 3
-4
-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10
^ ^
the ^ on the left is -5 and one number over is 4 which is the ^ on the right
15x +10y =400
All divide by 5
3x +2y =80
2y=80 - 3x
y=80-3x/2
Okay, so there's 100 pennies in a dollar and 100 x 200 = 20,000
Then to find our amount of millimeters we need to do 20,000 x 1.55 = 31,000 millimeters = 31 meters
Hope it helps!
