Answer:
Step-by-step explanation:
y-value is 0 and the x value is 5
h = 2
k = -1
Solve for (the coefficient of the squared term).
The coefficient of the squared term in the parabola equation is 1/9.
The problem statement gives you the relationship between their speeds, and it gives you information you can use to find their total speed. You solve this by finding the total speed, then the proportion of that belonging to Bill.
The total speed is (120 mi)/(3 h) = 40 mi/h.
The speed ratio is ...
... Bill : Joe = 3 : 1
so the speed ratio Bill : Total is ...
... 3 : (3+1) = 3:4.
Bill's speed is (3/4)×(40 mi/h) = 30 mi/h.
Answer:
the 3 represent a one thousand
so that means 4.oo9* 1000 = =49
Answer: her increase is 1.245 dollars an hour
Step-by-step explanation:
Minus 9x from both sides
-3y=-9x+12
divide both sides by -3
y=3x-4
