Answer: X^2-x-1=y
Step-by-step explanation:
Multiply every number inside the parentheses
(X+3)(x-4)
X^2-4x+3x-1
Add all similar numbers and we get
X^2-X-1
one paper sheet = 500 / 305 cents
134 * 13 = 1742
500 / 305 = 1.64 cents
1.64 * 1742 = $28.55
Answer:
f(x) = x³ x>1
Step-by-step explanation:
2 8=2³
3 27=3³
4 64=4³
5 125=5³
f(x) = x³ x>1
Answer:
y = (1/2)x - (15/2)
Step-by-step explanation:
goal: to rearrange the expression such that it is in the form
y = f(x); where f(x) is an expression in terms of x
given:
x - 2y = 15 (subtract x from both sides)
-2y = 15 - x (multiply both sides by -1 to make left side positive)
2y = -15 + x (divide both sides by 2 and rearrange)
y = (1/2)x - (15/2)
A factorial of 7 numbers is just multiplying 7 numbers together like this 1*2*3*4*5*6*7, which equals 5040.
If you wanted to get fancy, you could reword the questions and say, "what is the factorial of 5040?" In that case the answer is 1*2*3*4*5*6*7
