6-2x=y 14+3x=y plzzz helllllllllllllllp
pashok25 [27]

Answer:

(- \frac{8}{5}, \frac{46}{5} )

Step-by-step explanation:

Given the2 equations

6 - 2x = y → (1)

14 + 3x = y → (2)

Substitute y = 14 + 3x into (1)

6 - 2x = 14 + 3x ( subtract 3x from both sides )

6 - 5x = 14 ( subtract 6 from both sides )

- 5x = 8 ( divide both sides by - 5 )

x = - \frac{8}{5}

Substitute x = - \frac{8}{5} into either of the 2 equations for the corresponding value of y

Substituting into (1)

y = 6 - 2(- \frac{8}{5} ) = \frac{30}{5} + \frac{16}{5} = \frac{46}{5}

solution is ( - \frac{8}{5}, \frac{46}{5} )

The time to complete the construction of a soapbox derby car is normally distributed with a mean of three hours and a standard d
TEA [102]

Answer:

The probability that it would take more than four hours to construct a soapbox derby car = 0.1587 or 15.87\%

Step-by-step explanation:

Given -

Mean (\nu )  = 3 hours

Standard deviation (\sigma  ) = 1 hours

Let X be the no of hours to construct a soapbox derby car

the probability that it would take more than four hours to construct a soapbox derby car =

P(X > 4)  = P(\frac{X - \nu }{\sigma}> \frac{4 - 3 }{1})

                = P(Z > 1)                   Put (Z = \frac{X - \nu }{\sigma})

                 =  1 -  P(Z <  1)            

                 =  1 - .8413                    Using z table

                  = 0.1587
