For two functions, [tex]m(x)[/tex] and [tex]p(x)[/tex], a statement is made that [tex]m(x)=p(x)[/tex] at [tex]x=7[/tex]. What is definitely true about [tex]x=7[/tex]?
A. Both [tex]m(x)[/tex] and [tex]p(x)[/tex] cross the x-axis at 7.
B. Both [tex]m(x)[/tex] and [tex]p(x)[/tex] cross the [tex]y[/tex]-axis at 7.
C. Both [tex]m(x)[/tex] and [tex]p(x)[/tex] have the same output value at [tex]x =7[/tex].
D. Both [tex]m(x)[/tex] and [tex]p(x)[/tex] have a maximum or minimum value at [tex]x =7[/tex].
Answer (3)
3 x − 7 y = 19 3 x − 19 = 7 y y = 7 3 x − 19
See below. ;
To solve the equation 3 x − 7 y = 19 for y , we rearranged it to get y = − 7 3 x + 7 19 . This expresses y in terms of x as a linear equation with a slope and y-intercept. The final solution is y = − 7 19 − 3 x .
