Answer = C
because all are not in set pairs only no. C is pair of set
There can only be two definite x-intercepts, so your goal it to find 2 numbers of x that, when plugged into the equation, give you the answer of 0. 1 is the first x-intercept(4-24+20 equals 0). The second one is 5 (100-120+20 equals 0). So the average is 3, so the axis of symmetry is 3 since 5+1=6, and 6/2=3
Honestly, there is an easier way to find the axis of symmetry. the equation would be -b/2a, where as b is the coefficient in the second part of the equation, while a is the first coefficient in the equation. -(-24) is 24, and 4*2=8, so 24/8=3
I hope I actually answered this the way you wanted. You asked for an equation, but I just answered the axis of symmetry with very simple equation initially and another equation
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.

Answer:
x=16
(5x + 27)° =5(16)+27=80+27=107
(5x – 7)º= 5(16)-7=80-7=73
Step-by-step explanation
supplementary angle=180
(5x + 27)° + (5x – 7)º=180
5x+27+5x-7=180
10x+20=180
10x=180-20
10x=160
x=160/10
x=16
(5x + 27)° =5(16)+27=80+27=107
(5x – 7)º= 5(16)-7=80-7=73
107+73=180
