10⁻⁵ is the same number as 1 / 10⁵ .
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7

Answer:
y = 
x - 5
Step-by-step explanation:
Given f(0) = - 5 and f(4) = - 3 , then we have the coordinate points
(0, - 5) and (4, - 3)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 5) and (x₂, y₂ ) = (4, - 3)
m = 
= 
=
The line crosses the y- axis at (0, - 5) ⇒ c = - 5
y = f(x) = x - 5 ← equation of line
