It would take 11.5 hours. If he drove 460 miles in hours, his speed was about 57.5. Driving 661.5 miles at the same speed is equivalent to 11.5 hours.

Answer:
So lets isolate y
we have
-2x+3y=9
2/3x +2y=0
Im gonna do the first equation
so -2x + 3y = 9
Add 2x on both sides
3y= 9+ 2x
Now divide by 3 to isolate y
y= 3+ 2/3x
Now we can subsitute y into any eqaution (I’m gonna do the second one) to solve.
2/3x+ 2(3+ 2/3x)= 0
Solve:
2/3x+ 6 + 4/3x = 0
6/3x +6= 0
2x+6=0
2x= -4
x= -2
Now we can subsitute this for any equation.
so I’m gonna do the first equation
-2(-2)+3y=9
4+3y=9
3y= 5
y= 5/3
y= 1 2/3
Final answer:
x=-2
y= 1 2/3
Well the answer would be
6x2 ( 2 is an exponent) -7
2f(x) + 4 = 2(3x + 4) +4
Use the property
a(b+c) = ab + ac
2(3x+4) +4 = 2(3x) + 2(4) + 4
= 6x + 8 + 4
= 6x+ 12
