Answer:
Step-by-step explanation:
h(x)=44x+8-(30x+15)
=44x+8-30x-15
=44x-30x+8-15
=14x-7
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
The answer should be n= 1500
Answer:
5040
Step-by-step explanation:
every card in a 52 deck, is unique, and there are 7 cards drawn, without replacement, so your answer is 7!, 7! = 7*6*5*4*3*2*1=5040
Eight point six two is the answer
