The graph below shows the lines f(x)=1.1x+2.2 and g(x)=1.9x-0.75
. One combination of input and output values will satisfy both functions. How do you know this? Use the graph to estimate this combination of values. Then create a table of values for each function and use it to justify your answer.

In the figure attached, the lines are shown.

There is a combination of input and output that satisfy both functions  because both lines share a common point, that is, at that point values of f(x) and g(x) are equal. This point is (3.688, 6.256)

Table of values:

x             f(x)                                        g(x)

0             1.1(0)+2.2 = 2.2                    1.9(0)-0.75 = -0.75

1              1.1(1)+2.2 = 3.3                      1.9(1)-0.75 = 1.15

2             1.1(2)+2.2 = 4.4                     1.9(2)-0.75 = 3.05

3             1.1(3)+2.2 = 5.5                     1.9(3)-0.75 = 4.95

3.688     1.1(3.688)+2.2 = 6.256         1.9(3.688)-0.75 = 6.256

4             1.1(4)+2.2 = 6.6                     1.9(4)-0.75 = 6.85

step-by-step explanation:

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
