Answer:
x=-2
Step-by-step explanation:
The first step is to find the slope
m = (y2-y1)/ (x2-x1)
= (5-0)/(-2--2)
= (5-0) /(-2+2)
= 5/0
The slope is undefined
That means it is a vertical line (up and down) The x value does not change
x=-2
Statement Reason
1. 
Given
2. 
Distributive property of multiplication over addition
Let 'a', 'b' and 'c' be any real numbers. So, Distributive property of multiplication over addition states a(b+c) = ab + ac
3. 
Subtraction property of order
4. 
Addition property of equality
The addition property of equality states that if the same number is added to both sides of an equation, then the equation is still true.
5. x<1 Division property of equality
The Division Property of Equality states that if you divide both sides of an equation by the same nonzero number, the equation remain equal.
Answer:
45 yards and 176 yards
Step-by-step explanation:
Perimeter of a rectangular playing field = 2(Length + width)
P = 2(L+W)..................... Equation 1
From the question,
Let the width of the rectangular playing field = x yards,
The the Length = 4x-4 yards.
Given: P = 442 yards.
Substitute these values into equation 1
442 = 2(4x-4+x)
442/2 = 5x-4
221 = 5x-4
5x = 221+4
5x = 225
x = 225/5
x = 45 yards.
Width = 45 yards.
Length = (45×4)-4 yards = 176 yards
Hence the dimensions of the playing field are, 45 yards and 176 yards
