Solve 0 = - x^2 + 10x - 8

Mathematics
1 answer:
Bogdan [553]3 years ago
5 0

Answer:

x = 5 +- √17

Step-by-step explanation:

0 = -x^2 + 10x - 8

-(-x^2 + 10x - 8) = 0

Now do the quadratic formula with x^2 - 10x + 8 = 0

a = 1

b = -10

c = 8

x =  \frac{  - ( - 10) +  -  \sqrt{( -  {10)}^{2}  - 4 \times 1 \times 8} }{2 \times 1}

x = \frac{10 +  -  \sqrt{17} }{2}

x = 5 +  \sqrt{17}

x = 5 -  \sqrt{17}

GaryK [48]

Answer:

20% of 50 oz is 10 oz, but 20% of 60 oz is 12 oz.

This is because 60 is a larger number than 50, so percentage changes to it will be larger.

A group of campers is going to occupy 6 campsites at a campground. There are 16 campsites from which to choose. In how many ways
Pachacha [2.7K]

Answer:

The campsites can be chosen in 5,765,760 different ways.

Step-by-step explanation:

Given that a group of campers is going to occupy 6 campsites at a campground, and there are 16 campsites from which to choose, to determine in how many ways the campsites can be chosen, the following calculation must be performed:

16 x 15 x 14 x 13 x 12 x 11 = X

240 x 182 x 132 = X

240 x 24,024 = X

5,765,760 = X

Therefore, the campsites can be chosen in 5,765,760 different ways.

What would be the answer to x + 22 - 13x greater than or equal to 118
Fynjy0 [20]

Answer:.

x greater than or equal to -8

Step-by-step explanation:

x+22-13x≥118

Collect like terms

x-13x≥118-22

-12x≥96

Divide both sides by -12

-12x/12≥96/-12

x≥96/-12

x≥-8

The answer is x greater than or equal to -8
