Answer:
Step-by-step explanation:
Given sequence is: 4, 28, 196, 1372
28/4 = 7
196/28 = 7
1372/196 = 7
Since, the ratio of any two consecutive terms is same, so it is a geometric sequence.
Therefore,
Common ratio r = 7
First term a = 4
nth term of a geometric sequence is given as:
Answer:

6,02 %?= 67,5
602.?= 67,5
?= 67,5÷602
?=0,112
Answer:
slope is 7
Step-by-step explanation:
the rate of change is the slope
in the general equation y = mx + b
x and y are point coordinates (x,y)
b is the y intercept
m is the slope
this is the rate at which the points are changing essentially
a larger slope will produce a steeper line
a negative slope will produce a line pointed downward
a smaller slope will produce a flatter line
Answer:
Large books = 11
Small books = 6
Step-by-step explanation:
7x + 5y = 107
7x = 107 - 5y
x = 107/7 - 5y/7
5x + 7y = 97
5 (107/7 - 5y/7) + 7y = 97
535/7 - 25y/7 + 7y = 97
535/7 + 24y/7 = 97
535 + 24y = 679
24y = 679 - 535
y = 144/24 = 6: So x =
7x + 5(6) = 107
7x = 107-30
x = 77-7 = 11
