Standard form is Ax +By =c
y = -4/5 x -7
multiply by 5
5y = -4x -35
add 4x to each side
4x +5y = -35
multiply by -1
-4x -5y = 35
Choice D
The equation (5X-15=-75 is equal to B D and E because they all have -75 at they end of them!
The mean to your question is 62.3
you need to add all of the numbers together and then divide by how many numbers are there to find the answer.
Step-by-step explanation:
I am not sure, if something else is missing.
but given that one chart we can say that Craig had 2 fastest throws.
they were in the category 70-75 mph.
but we cannot say precisely which one was faster, and how fast it went.
it is also not clear what is the categorization of a border element (e.g. with an exact speed of 60 mph - is it in the 55-60 or in the 60-65 category ? or both ?).
I assume the upper limit of each interval is included, and the lower limit is excluded.
under this assumption we can say the fastest pitch was faster than 70 mph but slower than or equal to 75 mph.
