i cant give you a answer because there is no other problems
You just fill in for x (which is 4), and then you just multiply 6 and 4. Then you take the answer to that plus 9, which will give you y. Which is 33.
So
6(4) + 9
24 + 9
y= 33

Answer:
251.047804213 miles
Step-by-step explanation:
c1 t=3.5+1 speed 40 mph
c2 t=3.5 speed 50 mph
c1 40 *4.5= 180
c2 50 *3.5= 175
a^2+ b^2= c^2
180^2+175^2=c^2
32400+30625=c^2
63025=c^2
251.047804213=c
