well from my understanding of the problem and calculations i would say.. (-5.5,0)
Step-by-step explanation:
we see the common difference is
a2-a1 = 11x + 9 - 4x - 5 = 7x + 4
an = an-1 + (7x+4) = a1 + (n-1)×(7x+4)
for a7 we have then
a7 = 4x + 5 + 6×(7x +4) = 4x + 5 + 42x + 24 = 46x + 29
Answer:A
Step-by-step explanation:
To put a fraction into simplest form, you need to divide both the numerator and the denominator by the GCF of both of these numbers.
35 and 42 have a GCF of 7.
So, if we divide
35/7=5
42/7=6
Therefore, 35/42 in simplest form is 5/6
