Answer: She ordered 4 toppings.
Step-by-step explanation:
Given: Total cost of pizza = $ 12.90
Cost of pizza =$7.50
Price per topping = $1.35
Let x = Number of toppings,
Total cost of pizza = (Cost of pizza) + (price per topping) × (Number of topping)

hence, she ordered 4 toppings.
B) <span>Stocks tend to be better long-term investments than bonds because bonds do not have the same growth potential that stocks do.</span>
The mean GPA is greater than 2.75.
<h3>
What is GPA?</h3>
- A grade point average is a figure that represents the average of the final grades obtained in courses over time.
- A student's grade point average, sometimes known as a GPA, is computed by adding all accumulated final grades and dividing the total by the number of grades granted.
To find the GPA:
- GPA is calculated and could be utilized by the college to tell choices, which include the subsequent educational progression.
- Divide the total range of grade factors earned with the aid of the total number of letter-graded units undertaken.
- Mean GPA = total/50
- = 2.75.
Therefore, the mean GPA is greater than 2.75.

Find rates of change until you find a constant.
dy/dx=1,2,3,4,5,6
d2y/dx2=1,1,1,1,1
So the acceleration, d2y/d2x, is constant. This means that this is a quadratic sequence of the form a(n)=an^2+bn+c. So we can set up a system of equations to solve for the values of a,b, and c. Using the first three points, (1,1), (2,2), and (3,4) we have:
9a+3b+c=4, 4a+2b+c=2, and a+b+c=1 getting the differences...
5a+b=2 and 3a+b=1 and getting this difference...
2a=1, so a=1/2 making 5a+b=2 become:
2.5+b=2, so b=-1/2, making a+b+c=1 become:
1/2-1/2+c=1, so c=1 so the rule is:
a(n)=0.5x^2-0.5x+1 or if you prefer to not have decimals
a(n)=(x^2-x+2)/2
