$132(total) * 0.42(percent of gas) = $55.44 spent on gas
$132(total) - $55.44(gas) = $76.56 spent on electricity
Answer:
y= 7/5x or f(x)= 7/5x
Step-by-step explanation:
The x intercept is -5 which as a point is (-5,0)
The y intercept is 7 which as a point is (0,7)
- find slope
m=7/5
2. write equation
- (The equation can be written as either y equals or the function of x equals)
- y=7/5x
- f(x)=7/5x
The average number of failures can be found by multiplying .41 (equivalent to 41%) by 375. When you do this, you get 153.75 failures. Rounded to the nearest 10th is 153.8 failures; the nearest whole number, 154 failures.
Answer:
12
Step-by-step explanation:
h(x) = f(g(x))
Using chain rule:
h'(x) = f'(g(x)) g'(x)
h'(1) = f'(g(1)) g'(1)
h'(1) = f'(2) g'(1)
h'(1) = -4 × -3
h'(1) = 12
