Evaluate the polynomial 6x - y for x = - 3 and y = 2.

A. 15
B. –20
C. 4
D. –16
I think it is b...am I right?

6x = -18

-y = -2
so -20

Okay, I have another one but it will be a little more difficult...

Graph the Function
y = three minus the absolute value of x+2

Now, I know you can't actually graph it since you don't have the graph in front of you...But, how would I solve the equation?

actually the equation should be y= 3 less then the absolute value of x + 2!!!

y = |x+2| -3

first look at the graph of |x-3|

it is zero at x = 3 and goes up both ways from there with slope = 1 like the letter V
now move that whole graph down 3

solve for a: 2b=3/(a+c)

2 b (a+c) = 3

2 a b + 2 b c = 3

2 a = (3 -2 b c)/b

a = (3 - 2 b c)/ (2 b)

x:5/6a+1/4=3(1/3a+2/3)
