X + y = 32 . . . . . . . . (1)
x - y = 6 . . . . . . . . (2)
(1) + (2): 2x = 38
x = 19
The answer is b because 7 times 7 is 49
Answer:
Yes this is an arithmetic sequence.
Step-by-step explanation:
12 , 6 , 0 , -6, -12
Difference = 2nd term - first term = 6 - 16 = -6
It is an arithmetic sequence and each term is got by adding (-6)
Answer:
65 people.
Step-by-step explanation:
We have to work backwards.
We end with 63 people, and at the stop we lost 19 people and gained 17.
; if x = # people at the beginning
There were 65 people on the train to begin with.

Answer:</h3>
The slope is 4
<h3>
Step-by-step explanation:</h3>
We are given the equation;
y = 4x - 6
We are required to determine the slope of the line.
- We need to know that when an equation of a line is written in the form;
y = mx + c
- Then, m is the slope of the line and c is the y-intercept.
In this case;
The equation, y = 4x - 6 is already in the form of y=mx + c
Therefore;
The slope of the line 4
