Answer:
We know that the value of n will be negative.
Step-by-step explanation:
Since 15 is so much larger than 2, we know that the other value on that side would have to be a negative value. Since the coefficient is not negative, we know the variable must be.
True y=2x+1 and y-3x=4 it would be the same way because you can solve for x and you can solve for y
The linear function that models the total cost for x deliveries is:

-------------------
A linear function has the following format:

In which
- m is the slope, that is, the rate of change.
- b is the y-intercept, that is, the value of y when x = 0.
In this problem:
- Fixed cost of $9 per month,
. - Cost of $2 for each delivery, thus
.
The function for the <u>total cost for x deliveries is:</u>

Answer: 20 feet by 20 feet.
Step-by-step explanation:
1. You know that
is the original measure of one side. Since it is a square, all its sides are equal.
2. Therefore, to solve the problem you only need to solve for
, as you can see below:
- You have that:

- Then, you obtain the following quadratic equation:

- Apply the Quadratic formula to solve it:

- Then, you obtain:

3. The dimensions cannot be negative, therefore, the answer is: 20 feet by 20 feet.
The answer is 224.7 you got to turn 30% into decimal which is 0.30
then multiply 0.30 and 749 which equals 224.7
