When x = 3 and y = 5, by how much does the value of 3x2 – 2y exceed the value of 2x2 – 3y ?

Plug in the values.

3x^2-2y

3*3^2-2(5)
3*9-10
27-10
17

Next one.

2x^2-3y

2*3^2-3(5)
2*9-15
18-15
3

17-3= 15 

The value of 3x^2-2y exceeds 2x^2-3y by 15. 

I hope this helps!

Use math apps : ) like photo math to you out

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
