Answer:
3) y = 3x
Step-by-step explanation:
a line equation is typically written as
y = ax + b
a is the slope, the inclination of the line. it is defined as ratio of "y coordinate change / x coordinate change" when going from one point to another on the line.
so, e.g. going from (0,0) to (4,12) means
x changes by +4 (from 0 to 4)
y changes by +12 (from 0 to 12)
so, the slope is +12/+4 = 3
and the line equation starts like this
y = 3x + b
now, b is the y-intercept : the y value, where the line intercepts (crosses) the y-axis. in other words, the y value where x = 0.
and we have that right away, as the line goes through (0,0). that IS the y-intercept point. the y value there is 0.
therefore, b=0.
and so the full line equation is
y = 3x
This question can be interpreter as: If an integer is divided by 100, how many digits will be there after the decimal point?
The answer is that there will be 2 digits.
E.g. In a single digit number 6, 6 ÷ 100 = 0.06
In a double digit number 23, 23 ÷ 100 = 0.23
In a triple digit number 186, 186 ÷ 100 = 1.86
And so on...
Assuming that you are trying to find the values of a and s;
(2a+5s=41)3 -----> 6a+15s=123
-(3a+6s=54)2 -----> 6a+12s=108
6a+15s=123
-6a+12s=108
___________
0 + 3s=15
s=15/3
s=5
2a+5(5)=41
2a=41-25
2a=16
a=16/2
a=8

Answer:
I think that the answer is C
well, the movie lasted 1:38 so.... and she finished it at 1:10pm.
1:10pm minus 1 hour? 12:10pm.
12:10 pm minus 10 and minus 28 minutes? 12:10 - 00:10 = 12:00pm, 12:00 - 00:28 minutes = 11:32am.
