You dived 14.28/4.2 by taking the decimal out and when you get the answer put it back
Answer:
f(g(-64)) = -190
Step-by-step explanation:
The functions are not well written.
Let us assume;
f(x) = x+1
g(x) = 3x+1
f(g(x)) = f(3x+1)
Replace x with 3x+1 in f(x)
f(g(x)) = (3x+1) + 1
f(g(x)) = 3x + 2
f(g(-64)) = 3(-64) + 2
f(g(-64)) = -192+2
f(g(-64)) = -190
<em>Note that the functions are assumed but same method can be employed when calculating composite functions</em>
A = -4
If you plug in -4, it becomes -4x - 8y = 12 and if you turn this into slope-intercept form, it is y = -1/2x + 12.
The first equation, -4 = 3x + 6y, put into slope-intercept form is y = -1/2x - 2/3
They have the same slope, making them parallel.
Answer:
Equation: y = 1.5x + 8, where y = total cost and represents the dependent variable and x = the number of miles and represents the independent variable.
Step-by-step explanation:
The relationship between the total cost and the number of miles driven is a linear equation. That means that the rate of change is the same regardless of the number of miles driven. After the initial flat fee of $8, the rate is $1.50 per mile. So, in order to calculate the total cost of the trip, you will need to multiply the rate ($1.50) by the number of miles and then add the initial fee of $8. In this relationship, the total cost ('y') is the dependent variable, because it is dependent on the number of miles driven. The number of miles ('x') is independent because it is the cause of the total.
Answer:
8 hours and 175 minutes.
Step-by-step explanation:
So first add all the hours together: 2 + 2 + 1 + 2 + 1 = 8 Hours.
Then add all the minutes together: 17 + 48 + 53 + 19 + 38 = 175 Minutes.
Therefore, the team's score is 8 hours and 175 minutes.
I hope this helped!
