Hi there!
There is an initial cost of $210,000 (which you're just going to pay once)
Then it costs $500 per day to operate.
The number of days is represented by "x".
Your equation in function notation should look like this :
f(x) = 500x + 210,000
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
90
Step-by-step explanation:
Answer:
(3,4)
Step-by-step explanation:
first you're going to solve the equation -2x
your equation should now be: 
next you're going to substitute the given value of -2x into the equation 
so your equation should now be: 
next you're going to solve the equation for y
equation should now be: y=4
than you're going to substitute the given value of y into the equation 
×
then you're going to solve the equation for x
your equation should now be: x=3
then the possible solution of the system is the order pair: (x,y)=(3,4)
When we add or subtract polynomials, the addition or subtraction is applied to the coefficients of the terms of equal powers.
For the given polynomials, we are required to do subtraction as follows:
(-4.1 x^2 + 0.9 x - 9.8) - (1.7 x^2 - 2.4 x - 1.6)
= -4.1 x^2 + 0.9 x - 9.8 - 1.7 x^2 + 2.4 x + 1.6
= (-4.1-1.7) x^2 + (0.9+2.4) x + (-9.8+1.6)
= -5.8 x^2 + 3.3 x - 8.2
The final expression (solution) is:
-5.8 x^2 + 3.3 x - 8.2
Every step holds except for step 5
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
Here,
Step 1 is the result of the distribution of -5 while opening the parenthesis, So, Step 1 holds the distributive property.
Step 2, states adding like terms across each side, so combining as terms hold,
Step 3, Addition over the equal sign. So it also holds
Step 4, subtraction of 12 over the equal sign. So subtraction of the terms also holds.
Step 5, does not hold because the number 12 gets divided by 8 it is not an associative property.
Thus, Every step holds except for step 5.
