In y = 2x + 3, 3 represents the fixed cost and 2 represents the cost-per-mile.
The per mile charnge, in dollars per mile, is $2/mile (answer)
Answer:
1200 words
Step-by-step explanation:
If he types 40 words a minute, you have to multiply that by thirty because he typed 40 words 30 timers. 40 x 30=1200
The functions are illustrations of composite functions.
<em>The soil temperature at 2:00pm is 67</em>
The given parameters are:
---- the function for sun intensity
-- the function for temperature
At 2:00pm, the value of h (number of hours) is:


Substitute 8 for h in
, to calculate the sun intensity



Substitute 8/9 for I in
, to calculate the temperature of the soil



Approximate

Hence, the soil temperature at 2:00pm is 67

Which polynomial is equal to (-3x^2 + 2x - 3) subtracted from (x^3 - x^2 + 3x)?
<h3><u><em>
Answer:</em></u></h3>
The polynomial equal to (-3x^2 + 2x - 3) subtracted from (x^3 - x^2 + 3x) is 
<h3><u><em>Solution:</em></u></h3>
Given that two polynomials are:
and 
We have to find the result when
is subtracted from 
In basic arithmetic operations,
when "a" is subtracted from "b" , the result is b - a
Similarly,
When
is subtracted from
, the result is:

Let us solve the above expression
<em><u>There are two simple rules to remember: </u></em>
- When you multiply a negative number by a positive number then the product is always negative.
- When you multiply two negative numbers or two positive numbers then the product is always positive.
So the above expression becomes:

Removing the brackets we get,

Combining the like terms,


Thus the resulting polynomial is found
