Answer:
x=4
Step-by-step explanation:
The y axis is a line where the value of x does not change ( x=0)
It is a vertical line
The only line where the value of x does not change is x=4
It is a vertical line at x=4
35
2x+1=71
71-1=70
70÷2=35
therefore x must be 35
a₆ = a₇+(6-7)d = -4 -(-5) =1
5 mins difference
1 3/4 hours = 1 hour and 45mins
50-45=5mins
