Answer:

\frac{-55}{63}

Step-by-step explanation:

=\frac{2}{21}(\frac{-3}{13})-\frac{7}{9}-\frac{2}{21}(\frac{10}{13})

=\frac{-2}{91}-\frac{7}{9}-\frac{2}{21}(\frac{10}{13})

=\frac{-2}{91} +\frac{7}{9} -\frac{2}{21} (\frac{10}{13})

=\frac{-655}{819}-\frac{2}{21} (\frac{10}{13} )

=\frac{-655}{819}-\frac{20}{273}

=\frac{-55}{63}

Write an exponential function in the form y = ab" that goes through points (0,19)<br> and (6, 1216).
Elanso [62]

The exponential function is y=19*2^x

Step-by-step explanation:

The exponential function in the form of y=ab^{x}

First find the value of a and b if x=0 and y=19

y=ab^x\\\\19=ab^0\\\\\\19=a*1\\\\\\19=a

Find the value of b in y=ab^x

where x=6,y=1216  and a=19

1216=19b^6\\\\\\1216/19=b^6\\\\\\64=b^6\\\\\sqrt[6]{64} =b\\\\2=b

The function is y=19*2^x

How many solutions would there be for the following systems of equations <br>y=3x-5<br>6x-2y=10​
Ann [662]

Answer:

So the solution would be (1,-2). Remember you can always validate that the solution is correct by plugging it into both equations. But this is the same as the first equation, y=3x-5. Since they are the SAME line they will have infinite solutions.
