Answer:
x=2
Step-by-step explanation:
The axis of symmetry can be calculated using the following formula:

In order to use this formula, we need to have the function written in it's polynomial formula:

In order to do so, we have to isolate Y from the excercise's formula.

Then we resolve the square of the binomial knowing that (a+b)^2=a^2+2.a.b+b^2


Now we have that:



As we have now the polynomyal formula, we know that a=-2, b=8 and c=-13. We supplant on the formula and get:




The relation below is a function I don’t now of this right I’m in a rush
Answer:
The number of blocks in one hour is the same that the unit rate, so 16 blocks per hour
Step-by-step explanation:
we know that
To find out the unit rate, divide the total blocks by the total time
so

9514 1404 393
Answer:
90
Step-by-step explanation:
10! = 10 × 9 × 8!
so 10!/8! = 10×9 = 90

The factorial of an integer is the product of that integer and all the positive integers less than it. So, 3! = 3×2×1, for example. 0! is defined as 1.
The answer is in the enclosed diagram
