Which are the solutions of x2 = –5x + 8?
Nostrana [21]

Answer:

As exact answers:

x=\frac{-5-\sqrt{57} }{2}  and  x=\frac{-5+\sqrt{57} }{2}

As decimal answers:

x = -6.2749172 ≈-6.3

x = 1.27491722 ≈  1.3

Step-by-step explanation:

For quadratic equations, you can use the quadratic formula. Rearrange the equation to standard from, which is ax² + bx + c = 0.

x² = –5x + 8

x² + 5x - 8 = 0

State the values for "a", "b" and "c",

a = 1; b = 5; c = -8

x=\frac{-b±\sqrt{b^{2}-4ac} }{2a}            (Ignore the Â, it's a formatting error)

x=\frac{-5±\sqrt{5^{2}-4(1)(-8)} }{2(1)}           Simplify

x=\frac{-5±\sqrt{25-(-32)} }{2}               Two negatives make a positive

x=\frac{-5±\sqrt{57} }{2}  

Split the equation at the ± for plus and minus:

x=\frac{-5+\sqrt{57} }{2}  = 1.27491722 ≈ 1.3

x=\frac{-5-\sqrt{57} }{2}  = -6.2749172 ≈ -6.3

Therefore the solutions are 1.3 and -6.3.

What is the solution to this linear system?
seropon [69]
The answer is (-1,7)

I got this answer because to solve a system, you find the point on the graph where both lines intersect. And that point in this graph is (-1,7). Hope this helps!:)))))

10. MJ and Peter Parker leave school traveling in opposite
Paladinen [302]

Using proportions, it is found that:

  • Peter is walking at a rate of 3 km/h.
  • MJ is biking at a rate of 9 km/h.

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

  • Peter is walking at a rate of x km/h.
  • MJ is biking 6 km/h faster than Peter, thus 6 + x km/h.
  • Opposite directions, thus, their distance increases at a rate of (6 + 2x) km each hour, as 6 + x + x = 6 + 2x.

6 + 2x km each hour, 18 km after 1.5 hours, thus, the rule of three is:

1h - (6 + 2x) km

1.5h - 18 km

Applying cross multiplication:

1.5(6 + 2x) = 18

9 + 3x = 18

3x = 9

x = \frac{9}{3}

x = 3

x + 6 = 3 + 6 = 9

Then:

  • Peter is walking at a rate of 3 km/h.
  • MJ is biking at a rate of 9 km/h.
