3 : 4
Answer:
Last graph on the right.
Step-by-step explanation:
Try substituting some values for x and see which graph is valid.
when x = 0, y = f(0) = 3 = 3 (1) = 3
When we compare this to the graphs, we immediately see that the first 2 are not correct because in those cases, when x=0, y = 6 (i.e not 3).
Next we try x = 1
when x = 1, y = f(1) = 3 = 3 () = 2
Comparing the graphs ones again, show that only the last graph has x=1 and y = 2.
Find rate of change=(y2-y1)/(x2-x1)
Rate of change=(70-30)/(2-1)=40
F (x)=40x
F (12)=40 (12)=980
Answer:
7 + 2 + 5 = 143547
Step-by-step explanation:
This question needs to identify the pattern
the pattern
is
5 + 3 + 2 = 151022
First two digits: 5*3 = 15 multiple of first and second term
third and fourth digit: 5*2 = 10 multiple of first and third term
last two digit = First two digits + third and fourth digit - second term
= 15+10 - 3 = 22
similarly
9 + 2 + 4 = 183652
9*2 = 18
9*4 = 36
18+36 - 2 = 52
____________________________________
5 + 4 + 5 = 202541
5*4 = 20
5*5 = 25
20+25-4 = 41
_______________________
7 + 2 + 5 = ??????
7*2 = 14
7*5 = 35
14+35-2 = 49-2 = 47
thus, 7 + 2 + 5 = 143547
