Answer:C
Step-by-step explanation:
For every function; f(x) = y
Each value of 'x' produces only one output 'y'
A,B and D are not functions because this rule is violated. It is observed that on the graphs of A,B and D, there exists a value of x that produces two outputs(y).
Hence, C is the correct option as it produces only one output 'y' for each value of x.
We are given the ratio of 1/2 inch: 18 miles
Multiply both sides of the ratio by 2. I'm doing this so that the "1/2" turns into "1"
So we go from this ratio
1/2 inch: 18 miles
to this ratio
1 inch: 36 miles
which means that every inch on paper represents 36 miles in real life
----------------------------------------------------------------
The question is now: if two towns are 2.5 inches apart on paper, then how far are they in real life? (note: 2.5 is the decimal form of 2 and a half)
To find out, multiply both sides by 2.5
1 inch: 36 miles
2.5*(1 inch): 2.5*(36 miles)
2.5 inches: 90 miles
--------------------------------------------------------------------------
Answer: The two towns are 90 miles apart in real life
You set t up as 15/20 and you divide the fraction by 20/20, and then you get .75/1 so your answer could either be .75 miles per hour or 3/4 miles per hour
Answer:
Point form = (2,1)
Equation form = x=2 , y=1
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
