Well $25 is the standard price initially.
$10 is added every hour as a constant rate.
Therefore a. 25 + 10h is the right expression
Answer:
23
Step-by-step explanation:
The absolute value of any number is just the positive version of that number. For example the absolute value of -12 is 12.
Hope this helps! :)
Answer:
Step-by-step explanation:
We are given an expression to solve for the displacement (x), so in order to find velocity (v), we need to differentiate the function.

Using this equation, we can find the velocity if a value of t is given.
The solution to the system of equations is x = -1 and y = -1
<h3>How to solve the following
system of equations?</h3>
The system of equations is given as:
2x + 3y = 1
5x - 4y = 14
Multiply 2x + 3y = 1 by 2.5
So, we have:
5x + 7.5y = 2.5
Subtract 5x + 7.5y = 2.5 from 5x - 4y = 14
So, we have
7.5y + 4y = 2.5 - 14
Evaluate the difference and the sum
11.5y = -11.5
Divide by 11.5
y = -1
Substitute y = -1 in 2x + 3y = 1
2x + 3(1) = 1
This gives
2x + 3 = 1
Subtract 3
2x = -2
Divide by 2
x = -1
Hence, the solution to the system of equations is x = -1 and y = -1
