Answer:x - number of minutes;
f ( x ) - the distance from the finish line.
x : 0 2 4 6
f ( x ) : 3 2 1 0
f ( x ) = 3 - x/2
Answer: B ) f ( x ) = -1/2 x + 3
Step-by-step explanation:
Remember that the sum of tow cubes identity is:
So, to create our expression<span>, containing at least two variables, that can be factored using the sum of two cubes, we just need to replace </span>
and
with tow monomials with a different variable:
and
Lets replace those values in our identity:
Now that we have our expression, lets factor it using the sum of two cubes identity:
To verify if the factored form of our expression (right hand side) is equivalent to the original form (left hand side), we are going to expand the right hand side:
Since both sides of the equation are equal, we can conduce that the factored form of our expression is equivalent to the original expression.
The distance is -5 hope this helps
Answer:
31.5%
Step-by-step explanation:
If 70% of customers get an oil change, and 45% of those get their tires rotated, then this is a method I use to find the answers to these types of problems.
70% of customers, 45% of 70
One method that will help you so much is this simple equation: x% of y= y% of x. For example, if you need to find 3% of 50, the same value is given for 50% of 3, which would be 1.5. Using our given digits,45% of 70 is the same as 70% of 45.
A method that can add on to this is one I've come up with myself. If you divide your original number by 100, then multiply it by your given percentage, it will give you your wanted value, so if you plug in your values, 70/100, multiplied by 45, will equal 31.5%.
Use the formula for volume=LWH
