By definition of the binomial coefficient,
so we have
as required.
Answer:
{x,y} = {-2,-3}
Step-by-step explanation:
System of Linear Equations entered :
[1] -9x + 4y = 6
[2] 9x + 5y = -33
Graphic Representation of the Equations :
4y - 9x = 6 5y + 9x = -33
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 5y = -9x - 33
[2] y = -9x/5 - 33/5
// Plug this in for variable y in equation [1]
[1] -9x + 4•(-9x/5-33/5) = 6
[1] -81x/5 = 162/5
[1] -81x = 162
// Solve equation [1] for the variable x
[1] 81x = - 162
[1] x = - 2
// By now we know this much :
x = -2
y = -9x/5-33/5
// Use the x value to solve for y
y = -(9/5)(-2)-33/5 = -3
Answer:
75 cheeseburgers and 86 french fries
Step-by-step explanation:
This is a guessing math problem so do a random amount and change amount of items to get closer to the answer
81 x 3 = $243
80 x 1.50 = $120
243 + 120 = 363 -354 = 9 dollars
we need nine less dollars so 9/1.5 = 6 so six more fries
86 x 1.5 = 129
75 x 3 = 225
129 + 225 = $354
