Answer:
23.333 percent
Step-by-step explanation:
7/30 of the students are undecided.
Answer:
DOMAIN: -5, 2, 3 ,4
RANGE: 1, 3, 3 , 5
FUNCTION: Yes
Step-by-step explanation:
Since there is one value of y for every value of x this is a function.
The domain is just the x value (first number) and the range is just the y value(second number).
We must look at this question in steps
The first half of the journey is travelled at 40 km/h
Half of 100km is 50 km
Using the formula
Distance = Speed x Time
Speed = Distance / Time
Time = Distance / Speed
We can work out the time:
50km / 40km/h = 1.25 hours
Next we look at the second half of the journey
50km at 80km/h
50km / 80km/h = 0.625 hours
Add together both times to work out how long the entire journey took
1.25 + 0.625 = 1.875 hours
Using the Speed formula from before
Speed = 100km / 1.875 =
53 1/3 km/h or 53.3 recurring km/h
Answer:
c = 17
Step-by-step explanation:
Since this is a right angle triangle we can use the Pythagoras theorem that states that 
(where c is the Solve for hypotenuse and "a" and "b" are the legs of the right angle triangle). From here we know that the answer to this question is....
Answer:
Step-by-step explanation:
The slope-intercept form is given by y=mx+c, where m is the slope and c is the y-intercept.
Slope of given line= 
Parallel lines have the same slope. Thus, the slope of the line would also be .
The value of c can be found by substituting a pair of coordinates.
When x= 4, y= -1,
-1= -3 +c
<em>Add 3 to both sides:</em>
c= -1 +3
c= 2
Thus, the equation of the line is 
.
