Answer:
f(x) = 0x + 5
Step-by-step explanation:
Lets use the slope formula to determine the slope of this graph:

SO we know the slope is zero.
If we know the slope is zero, then the y intercept must be at 5.
So the equation would be:
f(x) = 0x + 5
Huh? that is difficult I have no idea
Answer:
its answer will be 9.first by using phythagorus theorem h^2=p^2+b^2'then h=15,p=12and b=x. again by putting the values of h ,p and b we get ,(15)^2=(12)^2+x^2. 225=144+x^2, x^2=225-144, x^2=81,x=√81,x=9 answer
Answer:
25 miles per gallon just look at the graph and simplify the slop of 50/2
for 9 gallons, 225 miles
multiply the rate by the # of gallons:9*25
