Answer:
3/25
f(x) = abx
f(0) = ab0 = a(1) = a = 3 (given)
f(1) = 3b1 = 3b = 15 ⇒ b = 5
f(-1) = 3•5-1 = 3/25
eg. x is the number of milk chocolate candy bars, y is the number of white chocolate of candy bar
x + y = 330
2x + 3y = 900
From first equation
x + y = 330
x = 330 - y
From second equation, subtitute x with 330 - y
2x + 3y = 900
2(330-y) + 3y = 900
660 - 2y + 3y = 900
660 + y = 900
y = 900-660
y = 240
The number of white chocolate candy bars is 240
Answer:
2 m/s
Step-by-step explanation:
Do 16 / 8 = 2
Check by doing 8 * 2 = 16
The answer is -6.57
In order to get this, we just treat it as a subtraction problem. Adding a negative number is the same thing as subtraction.
1.7 - 5 = -3.3
Now do the second part
-3.3 - 3.27 = -6.57
