Scrat [10]

Find the exact solution of -x2 +7x + 5 = 0 by using the Quadratic Formula.
jonny [76]

Answer:

The answer to your question is:

x 1 = -0.65

x2 = 7.65

Step-by-step explanation:

Equation              -x² + 7x + 5 = 0

a = -1

b = 7

c = 5

Quadratic formula     x = -b ±√(b² -4ac) / 2a

                                   x = - 7 ± √(7² -4(-1)(5) / 2(-1)

                                   x = -7 ± √(49 + 20) / -2

                                  x = -7 ± √69 / -2

                                   x = - 7 ± 8.3 / -2

               x1 = -7 + 8.3 / -2                         x2 = -7 -8.3 / -2

               x 1 = -0.65                                  x2 = 7.65

Chase collects $27.34 for a fundraiser Sydney collects$9.83 more than Chase ally collects 4times as much as Sydney. how much doe
adelina 88 [10]
So Chase has $27.34.
You add $27.34 to $9.83. (Which is $37.17).
That will give you the amount of how much Sydney has.
To find how much Ally has you times $37.17 by 4.
Basically, you are doing $37.17 + $37.17 + $37.17 + $37.17.
When you have finished adding them you will get the answer.
So the answer is $148.68
