I believe the answer is B because you multiply 18 and 40 then subtract 320 from that and you will 400.
Answer:
x=-2y-6
Step-by-step explanation:
Subtract 2y from both sides, and now you have x=-2y-6.
Since there is one value of y for every value of x this is both a relation and a function
Z = 114 + 2p
p = 46
Plug in 46 for 'p' in the first equation.
z = 114 + 2p
z = 114 + 2(46)
Multiply:
z = 114 + 92
Add:
z = 206
So the Zigzag river is 206 miles long.
