Why can't <img src="https://tex.z-dn.net/?f=x%5E2-5x-1" id="TexFormula1" title="x^2-5x-1" alt="x^2-5x-1" align="absmiddle" class
7nadin3 [17]

Answer:

Step-by-step explanation:

Discussion.

Not directly. But the quadratic formula can do it. But that's not your question.

the factors you get must contain the factors for 1 which are 1 and - 1

These factors must add to - 5. There's no way that will happen with 1 and - 1 and you would be creative math if you tried to say that you could make one of the factors (x -1-1-1-1-1-1). That creates a whole new question.

The sales of a certain product after an initial release can be found by the equation s=16√7t+62 where s represents the total num
Aleonysh [2.5K]
You want to replace the s with 150 in the equation and then just solve for t.
150=16√7t +62    subtract 62 from both sides
88=16√7t              divide both sides by 16
5.5=√7t                to get rid of the square root  square both sides. 
30.25=7t              now divide both sides by 7
4.3 = t (approximately) 
so at 4 weeks they will have sold 150 units.

What is the value of c in the equation below?! HELP
prisoha [69]

Note that when dividing, and the base is the same, you can subtract the power signs.

(5^5)/(5^2) = 5^(5 - 2)

5 - 2 = 3

5^3 = a^b

Simplify.

5^3 = 5 x 5 x 5

5 x 5 x 5 = 125

c = 125

----------------------------------------------------------------------------------------------------------------

125 is your answer
