Answer:
0
Step-by-step explanation:
To find the slope, we use the formula
m= (y2-y1)/(x2-x1)
= (6-6)/(-2-4)
= 0/-6
=0
In this question, we have to identify the zeros of the polynomial, along with a point, and then we get that the formula for the polynomial is:

------------------------
Equation of a polynomial, according to it's zeros:
Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.
------------------------
Identifying the zeros:
Given the graph, the zeros are the points where the graph crosses the x-axis. In this question, they are:

Thus





------------------------
Leading coefficient:
Passes through point (2,-8), that is, when
, which is used to find a. So




------------------------
Considering the zeros and the leading coefficient, the formula is:

Answer: 315 miles
Step-by-step explanation:
let onward speed = x mph, then distance = 7x
return speed = (x+18) mph, (same) distance = 5(x+18)
equating the two,
7x = 5(x+18)
2x = 90 ==> x = 45 mph
so distance = 7*45 = 315 miles
Answer:
sqrt(21)
Step-by-step explanation:
x = sqrt(7*3) = sqrt(21)
