What is the solution to 4x squared minus x minus 5 equals 0?
4x2 - x - 5 = 0 4x2 + 4x - 5x - 5 = 0 4x(x + 1) - 5(x + 1) = 0 (4x - 5)(x + 1) = 0 4x - 5 = 0 or x + 1 = 0 4x = 5 or x = -1 x = 5/4 o x = -1
What are the solutions to the inequality (x-3)(x plus 5)o?
If you mean (x-3)(x+5) = 0 then x = 3 or x = -5
Assume f of x equals 4x plus 8 and g of x equals 5 What is the value of g o f-1?
g(x) = 5. So whatever f(x) or f(-1) is, g of that is going to be 5.
5 x 5 x 5 x 5 x 5 x 5 x 5?
5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 = 78,125
How many possible outcomes would there be if three coins were tossed once?
Given that x is cross and o is head the possible outcomes would be: x-x-x o-x-x x-o-x x-x-o o-o-x o-x-o x-o-o o-o-o Thence there are 8 possible outcomes. Assumptions: 1) Each coin ends up head or tail (never on its side) 2) The coins are distinctinguishable (maybe a penny dime and quarter). If three identical perfectly balanced pennies are tossed at the same time there are 4 outcomes (all heads or all tails 1/8 of the time each and just one or just 2 heads 3/8 of the time each)
