The problem gives a distance with a fraction (not a decimal); there is absolutely no reason to convert it to a decimal. In 4 days, Val walks: 4*(2 3/5) miles 4*(13/5) miles [convert to improper fraction] 52/5 miles 10 2/5 miles [convert to mixed number] Compare that to Bill, who runs 10 miles every 4 days. Val runs a greater distance.
Simplified because I don’t know if x^o is the correct notation
(X^2 + 4) - (x^o + 5x - 1)
X^2 + 4 - x^o - 5x + 1
Then combine like terms
Answer:
Step-by-step explanation:
The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
Given the points A(h, k) and B(h,j)
x1 = h, y1 = k, x2 = h, y2 = j
Substitute into the formula;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
M(X,Y) = {(h+h/2, (k+j)/2}
M(X,Y) = {(2h)/2, (k+j)/2}
M(X,Y) = {h, k+j/2}
hence the coordinates of point M is {h, k+j/2}
Standard form is when x and y are on one side of the equations and the constants are on the other side. Moving the variables and constants around we get,

However we have to make sure the x is not negative. Multiplying all by negative one we get x-y=-1
