Percent of change will always be positive because the change is an absolute value. As we know, absolute value is always a positive value because you don't pay attention to the direction, only the distance is important.
ANSWER
x+y=1
EXPLANATION
We want to find the equation of line CD which passes through (0, 1) and is parallel to x + y = 3.
In slope intercept form, the given line is
y=-x+3
The slope of this line is m=-1
Line CD also has the same slope
The equation is given by:
y=mx+b
The given point (0,1) means the y-intercept;is b=1
Hence the equation is
y=-x+1
In standard form the equation is:
x+y=1
<span>The solution for a system of equations is the value or values that are true for all equations in the system. The graphs of equations within a system can tell you how many solutions exist for that system. Look at the images below. Each shows two lines that make up a system of equations.</span>

When the lines intersect, the point of intersection is the only point that the two graphs have in common. So the coordinates of that point are the solution for the two variables used in the equations. When the lines are parallel, there are no solutions, and sometimes the two equations will graph as the same line, in which case we have an infinite number of solutions.
Some special terms are sometimes used to describe these kinds of systems.

Answer:
A: 33.5
B: 24.5
Step-by-step explanation:
The formula for the law of cosines is:
a^2 = b^2 + c^2 - 2*b*c*cos(angle)
In this triangle b = 7, c = 8 and angle = 32.
a^2 = 7^2 + 8^2 - 2*7*8*cos(32)
a^2 = 18.018
a = SQRT(18.018)
a = 4.24
C = 4.2 feet.
