D = rt

D = 50(4)

D = 200 miles

From a coordinate point of view, we have a function D(x) = 50x, where x represents time in hours.

When x = 4, y = 200.

(x, y) = (domain, range).

Our domain is 4 hours and range 200 miles.

Blake and Ned work for home remodeling business they are putting the final touches on a home they renovated. working alone Blake
stiks02 [169]

Answer:

3.6 hours

Step-by-step explanation:

Blake can do work in hours = 9

Blake can do a part of work in 1 hour = \frac{1}{9}

Ned can paint the same room in six hours.

Ned can do a part of work in 1 hour = \frac{1}{6}

They can do a part of work together in 1 hour =  \frac{1}{9}+\frac{1}{6}

                                                                           =  \frac{5}{18}  

Now they can do \frac{5}{18}  part of work in hour = 1

So, they can do whole work in hours =  \frac{1}{\frac{5}{18}}

                                                             =  3.6

Hence it will take 3.6 hours to paint the room if they work together.

Determine the values of the parameter s for which the system has a unique​ solution, and describe the solution. sx 1 minus 2 sx
JulijaS [17]

Note: The equations written in this questions are not appropriately expressed, however, i will work with hypothetical equations that will enable you to solve any problems of this kind.

Answer:

For the system of equations to be unique, s can take all values except 2 and -2

Step-by-step explanation:

2sx_{1} + 4x_{2} = -3\\2x_{1} + sx_{2} = 4

\left[\begin{array}{ccc}2s&4\\2&s\end{array}\right] \left[\begin{array}{ccc}x_{1} \\x_{2} \end{array}\right] = \left[\begin{array}{ccc}-3 \\6 \end{array}\right]

For the system to have a unique solution, \begin{vmatrix} 2s & 4 \\ 2 & s \end{vmatrix} \neq 0

2s^{2} -8 \neq 0\\2s^{2}\neq 8\\s^{2}\neq 4\\s \neq 2 or -2
