Use elimination method - I am eliminaing the y-variable.
1(5x + 8y = 16) → 5x + 8y = 16
4(6x - 2y = 54) → 24x - 8y = 216
Add equations: 29x = 232
Divide by 29: x = 8
Answer: x = 8
F(x) - g(x) = -2x^3 - 6x^2 + 9x
Answer:
48 questions.
Step-by-step explanation:
x is for the unknown variable, the number you are trying to figure out.
12= 25%x
if you convert to a fraction, 12 is 1/4 of x. if you then multiply your answer by 4, 12 is 25% of 48.
to figure this out you can also ask, 12 is 25% of what number?
The range of the dataset = 47
What is the range of a dataset?
The range of a set of data is the difference between the greatest number and least number
The given data set is:
{14, 25, 61, 18, 30, 32, 28, 45, 21}
The greatest number = 61
The least number = 14
The range of the dataset = Greatest Number - Least Number
The range of the dataset = 61 - 14
The range of the dataset = 47
