larisa [96]

Step-by-step explanation:

<u>A</u><u>.</u><u> </u><u>Line up the decimals, then multiply as you would with whole numbers:</u>

21.33 \\\times 2.04 \\  = 43.5132

<u>B. Line up the decimals, then add as you would with whole numbers:</u>

Note: These decimals aren't lined up exactly.

1.115 \\  + 3.18 \\  = 4.295

22.061 \\  + 4.295 \\  = 26.356

26.356 \\  + 12.2384 \\  = 38.5944

Determine the expression you can substitute for y in to solve the system below.
FromTheMoon [43]

Answer:

Step-by-step explanation:

given are the two following linear equations:

                       f(x)  =  y  = 1 +  .5x

                       f(x)  =  y  = 11 -  2x

Graph the first equation by finding two data points.  By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis.

           If x = 0, then  f(0)  =  1  + .5(0)  =  1

           If y = 0, then  f(x)  =  0  = 1  +  .5x

                                               -.5x  =  1

                                                    x  =  -2

           The resulting data points are  (0,1)  and  (-2,0)

Graph the second  equation by finding two data points.  By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis.

           If x = 0, then  f(0)  =  11  - 2(0)  =  11

           If y = 0, then  f(x)  =  0  = 11  -  2x

                                               2x  =  11

                                                    x  =  5.5

           The resulting data points are  (0,11)  and  (5.5,0)

At the point of intersection of the two equations x and y have the same values.  From the graph these values can be read as x = 4 and y = 3.
