Point p on the number line represents, -7
Should be false because -7 x -7 is not -49 it is 49
With the current 40 miles per hour
Against the current 30 miles per hour
bv means boat velocity with NO current
cv means current velocity
A) bv + cv = 40 mph
B) bv - cv = 30 mph
Adding both equations:
2bv = 70
boat velocity with NO CURRENT = 35 miles per hour
Using equationA
bv + cv = 40
35 + cv = 40
current velocity = 5 miles per hour
8y-3=6y+17 first subtract 6y from both sides to make it
2y-3=17 then add 3 to both sides to get 2y=20 then you will divide each side by 2 and you get y=10
