Answer:
C) 20 hours
Step-by-step explanation:
x = number of hours
A yard cleanup service charges a $380 fee plus $14 per hour.
380 + 14x
Another cleanup service charges a $260 fee plus $20 per hour.
260 + 20x
How long is a job for which the two companies' costs are the same?
380 + 14x = 260 + 20x
380 - 260 = 20x - 14x
120 = 6x
20 = x
Answer:
The system that models the situation is:

The solution is:
(9, 6)
Step-by-step explanation:
We must write the equations as indicated in the problem.
The sum of twice a number and another number is 24
<em>a number:</em> x
<em>other number:</em> y
Then

The difference of twice the first number and the other number is 12
<em>first number: </em> x
<em>other number:</em> y
Then:

The system that models the situation is:

To solve the system we add both equations to find the value of x

Answer:
True
Step-by-step explanation:
Hello!
This question is about which values you are changing when you are transforming an equation.
Let's go through the parent function for an absolute value equation and its various transformations.

Since we are only looking at horizontal and vertical transformations, we only need to worry about the c and d values.
The c value of a function determines a function's horizontal position, and the d value of a function determines a function's vertical position.
One thing to note here is that the c value is being subtracted from the x value, meaning that if the function is being transformed to the right, you would actually be subtracting that value, while the d value behaves like a normal value, if it is being added, the function is transformed up, and vice versa.
Now that we know this, let's write each expression.
a) 
b) 
c) 
d) 
Hope this helps!
