Answer:
35
Step-by-step explanation:
96 (for company A)=75+.60x (x is for the number of miles)
96=75+.60 x
I forgot how I got 35, but I plugged it back into the equation and it worked.
Answer: A
Step-by-step explanation: The question states that the change wasn't a positive one, it was a negative one as it states that the temperature changed an average of -2.250 Fahrenheit per hour. So, we multiply that by 3 to get -6.75. This is why A is correct.
The average cost represents the slope of the line of the graph.
Increasing the slope of the graph increases the steepness of the line.
Therefore,
increasing the average cost of gas from $1.50 to $2.20 will increases
the steepness of the line. (i.e. the line becomes closer to the vertical
line).
Answer:
4d (the variable is usually x, though).
Step-by-step explanation:
Because 4 x the amount of fish in each tank = total amount of fish
Answer:
Cos 2x+sin x = cos x cos x - sin x sin x + sin x
Step-by-step explanation:
Cos 2x+sin x
use Trigonometric identities.
cos (2x) = cos (x + x) = cos x cos x - sin x sin x
Cos 2x+sin x = cos x cos x - sin x sin x + sin x
