Answer:
[tex]x=-5/7[/tex]
Step-by-step explanation:
we have
[tex]f(x)=7x+5[/tex] ----> The degree of this polynomial is 1 (linear equation)
Remember that
The zero of the polynomial is the value of x when the value of f(x) is zero
so
For f(x)=0
[tex]0=7x+5[/tex]
solve for x
[tex]x=-5/7[/tex] ----> the zero of the polynomial or x-intercept
