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.
<span>Hello,
For this 12x-3x+11>4x-(17-9x)let's rewrite it as:
12x-3x+11>4x-17+9x
Now combine like terms:
9x+11>13x-17
Subtract 9x and add 17 to get:
28>4x
Divide by 4:
7>x or rewritten as:
x<7
Make sense?</span>
Given:
Fixed salary = $1400
Additional salary = $500 each time he sells a car.
To find:
The equation for the situation and how much money he will make if he sells 7 cars.
Solution:
Let y be the total salary of the salesman after selling x cars.
He will earn an extra $500 each time he sells a car. So, extra money earned by him after selling x cars is 500x.
Total salary = Fixed salary + Additional salary
Substituting 
, we get
Therefore, the required equation for the given situation is and the salesman will earn $4900 if he sells 7 cars.

- Solving quadratic equations
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
y = x² + 8x
<u>Step 2: Find Roots</u>
- [Quadratic] Factor: y = x(x + 8)
- [Quadratic] Set up [Solve]: 0 = x(x + 8)
- [Quadratic] Define: x = 0, -8
∴ the roots of the quadratic equation y = x² + 8x is equal to 0 and -8.
