Answer:
180
Step-by-step explanation:
According to the table, the relationship between the x and the y value is 20, (4*20 = 80) (5*20 = 100) etc.
The graph with the points has a relationship of 35 (2*35 = 70) (4*35 = 140) etc. Therefore, you can figure out what y-value 12 would have for the table and the graph by multiplying 12 by 20 or 35 respectively.
12*20 = 240
12*35 = 420
420-240 = 180
Answer:
an= 12 + (-6)(n-1)
Step-by-step explanation:
you should find two values: a1 and d
a1= first number =12
d= a number of the sequence mines the number of the sequence before the one you chose = 0-6 = -6
a1+(n-1)d= 12-6(n-1)
Answer:
7x^2+21x+14
Step-by-step explanation:
With this all we have to do is foil:
first outside inside last
first: 7x^2
outside: 14x
inside: 7x
last: 14
we now combine them to
7x^2+14x+7x+14
we add like terms
7x^2+21x+14
