We want to answer different things regarding linear equations.
The answers are:
1) We want to see which function matches the given graph.
So, we can see that this is a linear function, that passes through the origin, so the y-intercept is y = 0.
We also can see that it passes through the point (2, 1).
Then we have that:
1 = a*2 + 0
1/2 = 0.5 = a
So the linear equation is:
y = 0.5*x
Here the correct option is d.
2) We know the relation:
distance = speed*time
So any permutation of these values can be used to find the time.
Then the option that can not be used to find the travel time is:
b) 70/200 = t
Because in this case, we are taking:
speed/distance = time
And that is incorrect.
3) We have the formula:
500 = 100*x
Again, using:
Distance = speed*time
The options that are correct are the ones where 500 represents a distance and the 100 represents time or speed, then the correct options are:
a and c.

Answer:
true
Step-by-step explanation:
a prime number is an odd number.
If you add 1 to an odd number, it will become an even number, then it is divisible by 2.
Answer:
14 it is not 14
Step-by-step explanation:
114
Just use the Pythagorean theorem and then multiply by 2 to find answer. See picture to see how I did it.
Answer:
Overall, the steps for algebraically finding the range of a function are:
1.Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
2.Find the domain of g(y), and this will be the range of f(x).
3.If you can't seem to solve for x, then try graphing the function to find the range.
