The graph is uploaded in the attachment.
The value of x is 2.625.
Step-by-step explanation:
let us plot f(x), g(x) on y-axisso, f(x)=y and g(x)=y.
the first equation can be written as y=5-2xthe general equation of a straight is y=mx+c( where m is the slope and c is the y-intercept )
now comparing given equation with the general equation mentioned above, the slope of first line is -2 and its y-intercept is 5the slope of second equation i.e, y=(2/3)x-2 is 2/3 and its y-intercept is -2.now plot the graph using above information.(y-intercept is the the coordinate of a point where the line intersects y-axis)
(slope is the angle made by the line with the x-axis)
by seeing the graph, the value of x is 2.625.Ответ:
