<em><u>Solution:</u></em>
Given that we have to perform the indicated operation
Given polynomial is:
Polynomial addition\subtraction is similar to arithmetic addition\subtraction
Add\subtract the terms of coefficients with same variable with same exponent
For example: 
To subtract Polynomials, first reverse the sign of each term we are subtracting
Which means, reverse the sign of each term in second bracket
Thus the given operation is performed
Wilson can be correct because the functions x=-1 and x=1 are linear functions with no slope (no rate of change). The average y value of these functions is zero. Another function that has an average y value of 0 and no rate of change would be the function x=0. Since all of the y values of this function are 0, there is no rate of change and the average y value is zero itself is zero. Therefore, Wilson is correct. The function that Alexis described is a sinusoidal function. The equation for the function that Alexis described is f(x)=sin(x). The natural sinusoidal function oscillates around the average y=0 with maximums at y=-1 and y=1. A sinusoidal function goes up through a turning point and comes back down, and given this, Alexis is also correct.
Based on point P(0,16), we substitute in the parabola to find a.
16=a(0-3)^2-2 => a=(16+2)/9=2
so the parabola is
y=2(x-3)^2-2 ..........................(1)
Solve for zeroes of (1);
0=2(x-3)^2-2 => (x-3)^2=1 => x=2 or x=4
Now the line passes through (0,16), (4,0) => y,x intercepts are 16 & 4.
Using the symmetric form
x/4+y/16=1
4x+y=16 => y=16-4x
I hope this helps you
m = 7-3/3-1
m =2
y -3= 2.(x - 2)
y = 2x+1
2x-y+1=0
By applying the property of similar triangles, the distance Amana from point A to B walked is: B. 226 ft.
<h3>How to determine the distance?</h3>
By critically observing the diagram (see attachment), we can deduce that two (2) similar triangles were formed by the First Ave. and Second Ave.
By applying the property of similar triangles, the distance Amana walked is given by:
(AB + 113)/113 = (280 + 140)/140
(AB + 113)/113 = 420/140
(AB + 113)/113 = 3
AB + 113 = 3 × 113
AB + 113 = 339
AB = 339 - 113
AB = 226 ft.
