4.Given w(x) =3×-2, v(x) =2×+7 and k(x)= -6x-7, find (w-v-k) (2)?​
Ivan

Answer:

12

Step-by-step explanation:

We input 2 into each function:

w(2) = 3(2) - 2 = 4

v(2) = 2(2) + 7 = 11

k(2) = -6(2) - 7 = -19

Then we place our answers in w - v - k

(4) - (11) - (-19)

= 4 - 11 + 19

= 12

Solve x2−5x=8 by completing the square. Round your answers to the nearest hundredth.
Bogdan [553]

Answer:

x = \dfrac{5}{2} \pm {\dfrac{\sqrt{57}}{2}

Step-by-step explanation:

x^2 - 5x = 8

x^2 - 5x + \dfrac{25}{4} = 8 + \dfrac{25}{4}

(x - \dfrac{5}{2})^2 = \dfrac{57}{4}

x - \dfrac{5}{2} = \pm \sqrt{\frac{57}{4}}

x = \dfrac{5}{2} \pm {\dfrac{\sqrt{57}}{2}
