f(x) = x^2 - 13x + 30

Step-by-step explanation:

A quadratic equation may be expressed as a product of the two binomials. The roots of the equations are 3 and 10, so the factors are (x-3) and (x-10).

f(x) = (x-3)(x-10)  

f(x) = x^2 - 13x + 30

Use the elimination method to solve the system of equations.<br> 2x + 3y = 8<br> x - y = 9
krek1111 [17]

Answer:

Okay you have isolate a variable. As long as you perform the some operation on both sides the equations holds true. So I'll multiply the bottom one by three. 3x - 3y = 27. Now if I add the equations together I get 5x is 35 or x is 7. Then plug it back into either equation. 7 minus what is 9? -2. Y is -2

Answer:

The range here is 85

Step-by-step explanation:

Here, we want to calculate the range of the data

Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset

From the given data points, the highest value is 189, while the lowest value is 104

So the range is the difference between the two which is;

189-104 = 85
