TO write the function into vertex form, we need to add one zero and the solution is shown below:
f(x)= x² -6x +1
Add one zero in the form of -9 and 9, such as:
f(x) = x² -6x +1 -9 +9
f(x) = (x² -6x +9) +(1-9)
f(x) = (x-3)² + (-8)
f(x) = (x-3)² - 8
This is the vertex form of the given function and only one zero is being added.
Answer:
z = -b - 17 / ( a + 4 )
Step-by-step explanation:
az + 17 = -4z – b
collect like terms
az + 4z = -b -17
z( a + 4 ) = - b - 17
Divide both sides by ( a + 4 )
z = -b - 17 / ( a + 4 )
You said it yourself... the phrase "900 miles at 30 miles per hour" means that the fraction 900/30=30 is showing how many hours it takes to do 900 miles at a speed of 30 miles an hour. So, it took 30 hours. As with your question, I am not entirely sure of what you are asking, but from the answer choices, the most logical would be the last one, 900 miles/ ? hours. If you implement the number of hours that it takes to drive 900 miles at 30 miles per hour, the fraction would be 900 miles/ ? hours, which would then show the rate that you are driving at, 30 miles per hour.
Answer: The answer is the first bubble
Step-by-step explanation:
1. When you identify the pairs you get: { ( -5,-4), (-1,5), ( -5,3) , (7,8) }
2. When figuring out whether or not it is a function, you have to see if there are any same y values. If there is no y values that are the same, then the relation is a function.
3. This relation is a function.
* Also, if you have a relation that has the two or more of the same x values, the relation is still a function no matter what.
