Answer:

Step-by-step explanation:
{700 = <em>S</em> + <em>A</em>
{4500 = 5<em>S</em> + 10<em>A</em>
−⅒[4500 = 5<em>S</em> + 10<em>A</em>]
{700 = <em>S</em> + <em>A</em>
{−450 = −½<em>S</em> - <em>A</em> >> New Equation
_____________

[Plug this back into both equations above to get the A-value of 200]; 
Answer: is If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.
Step-by-step explanation: answer is A
Answer:
x > -1
Step-by-step explanation:
-10 < x - 9
Add 9 to each side
-10+9 < x - 9+9
-1 < x
x > -1
Equation in slope-intercept form:
y=mx+b
m=slope
b=y-intercept
Data:
m=-32
b=7
Therefore:
y=-32x+7
Answer: y=-32x+7
