Answer:
B) 
Step-by-step explanation:
The range is the lowest point to the highest point on the graph.
Remember this:
1. domain (x-axis) LEFT –> RIGHT
2. range BOTTOM (y-axis) –> TOP
when this equation is graphed over the domain, it limits the range to being (8,–5) and (–8,–1) and since with range you only look at the y-coordinates that means that the range is [–5,–1]
Answer:
x is less than -3
Step-by-step explanation:
3x^2+9x<0
x^2+3x<0
x(x+3)<0
x+3<0
x<-3
Area = (h/2)(a +b)
where h = distance between the 2 parallel line segments and a and b are the lengths of these 2 line segments.
Let <em>x</em> = 8.132132132...
Then 1000<em>x</em> = 8132.132132132...
Subtract <em>x</em> from 1000<em>x</em> to eliminate the fractional part:
1000<em>x</em> - <em>x</em> = 8132.132132132... - 8.132132132...
999<em>x</em> = 8132 - 8 = 8124
<em>x</em> = 8124/999 = 2708/333

Answer:
A. no solution
B. unique solution: (x, y) = (0, 0)
Step-by-step explanation:
For these problems, you can subtract the second equation from the first to get something of the form ...
0 = (expression)
The solution of that will tell you the answer.
__
A. (2x +3y) -(2x +3y) = (4) -(9)
0 = -5 . . . . . . . . no values of x or y will make this true: NO SOLUTION
__
B. (y) -(y) = (6x) -(x)
0 = 5x
0 = x . . . . . . divide by the coefficient of x.
y = x = 0
The unique solution is (x, y) = (0, 0).
