Answer:
B
Step-by-step explanation:
If you look at A and you subtract 3x by 4x you get x and you subtract 3 from -7 and you get -10. But if you look at B you do the stuff in the parentheses first and you get 4x+12x+28=16x+28 and they're the same so it's B.
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x=2/3, 0
The first one all the way to the left is the correct graph of 4x-3y=24.
The equation which relates speed, V and time, t to the total distance traveled is 70 = Vt
- 70 = Vt
- v(5) = 14
- V(7) = 10
- V(3.5) = 20
Since he is traveling at a constant speed, the relationship between, V and t can be written thus :
- Distance = speed × time
- 70 = Vt
<u>At time, t = 5 </u>
<u>At time, t = 7 </u>
<u>At time, t = 3.5</u>
Therefore, the relationship between V and t with distance is 70 = Vt

Answer:
The correct answer is Total Cost Payable = $Exp + $15, where $Exp is the total price of the groceries bought by Barbara
Step-by-step explanation:
Barbara orders her groceries. Let us consider that she orders groceries worth $Exp from a store.
Extra charges levied by the store for delivering the groceries to Barbara's house is $15.
Thus the total payable charge by Barbara for her groceries should include the total price of the groceries and the delivery charges levied by the store.
Thus the Total Cost Payable by Barbara is the sum of the total expenditure by her on the groceries and the delivery charge.
∴ The total cost payable = $Exp + $15.
