0.032x+0.041 (1500-x)=54.3
Solve for x
0.032x+61.5-0.041x=54.3
0.032x-0.041x=54.3-61.5
-0.009x=-7.2
X=7.2/0.009
X=800 invested at 3.2%

1500-800=700 invested at 4.1%

When looking at a rational function f of x equals the quantity x plus three times the quantity x minus two times the quantity x
geniusboy [140]
f(x)=\frac{(x+3)(x-2)(x+5)}{(x-3)(x+2)(x-5)}

Bobby is right, because at x = -2, 3, and 5, the denominator of the function equals zero, which is by definition undefined.

Factor: 8ab - 16ac + 12a
aksik [14]
The GCF we factor out is 4a

8ab = 4a*2b
16ac =  4a*4c
12a = 4a*3

Each term has been factored so that 4a is a factor

Using those factorizations, we can use the distributive property in reverse
8ab - 16ac + 12a = 4a*2b - 4a*4c + 4a*3
8ab - 16ac + 12a  = 4a*(2b - 4c + 3)

Answer is choice A<span />

(3,4) and (-5,6) are "coordinate planes".

These appear in algebra and math when you're graphing. These coordinate planes consist of "x" and "y" (x,y). The x's (which are 3 and -5 in your situation) should be graphed accordingly using the x-axis and the y's (which are 4 and 6 in your situation) should be graph accordingly using the y-axis.
